Significant fluctuations in water levels along the Juba River have been observed. The Juba River surpassed the high-risk thresholds by 10 cm at Luuq on 21st October before decreasing below moderate risk level as of today. Downstream at Bardheere Station, the water level rose from 8.00 m on 21st October to 9.00 m and crossing high-risk threshold (8.20 m) on 22nd October before receding back to 8.00 m today. The downstream flow of the flood wave has led to a 1.1 m rise in the water level at Bualle which currently poses no immediate threat of riverine flooding. Moderate to heavy rains (50 – 100 mm) are expected over the catchment of Juba River within Gedo region and near-border areas with Ethiopia between 23rd and 29th October. The rains over the upper catchment in Ethiopian Highlands may exceed 200 mm posing high risk of riverine flooding towards the end of the forecast period. There is a high risk of flash flooding due to potential localized heavy rains over western parts of Bakool, central parts of Gedo, and Saakow district in Middle Juba region. The water levels along the upper part of Shabelle River are on downward trend. On 21st October, the water level at Beletweyne (6.44 m) was only 6 cm below the moderate flood risk threshold. The levels have since dropped to 6.10 m today. The downstream flow of the flood wave has led to an increase in the water level at Bulo Burte from 4.95 m on 21st October to 5.28 m today. The water level at Jowhar station has also risen during the same time from 3.95 m to 4.28 m. These levels, at both stations, are still below riverine flood risk thresholds. Moderate rainfall (31.5 mm) led to flash floods that affected Badda Cas IDP camp interrupting livelihood activities. Moderate rainfall of about 50 mm is expected over Shabelle River catchment within Hiraan region and near-border areas with Ethiopia. Coupled with the heavy rains recorded one week ago, the heavy rains (more than 150 mm) forecast over the Shabelle River upper catchment in Ethiopian Highlands, are likely to pose high risk of riverine flooding at Beletweyne towards the end of October and beginning of November 2023.

Somalia grapples with the looming impacts of an impending El Niño, exacerbating the ongoing climate change challenges. Recurrent riverine and flash floods, particularly in urban centers are of significant concern. Urgent action is needed to prepare for and mitigate the forthcoming El Niño floods, aiming to safeguard lives and mitigate economic losses. Key to this strategy is proactive flood management, involving timely evacuations to higher ground. Identifying suitable elevated areas serves a dual purpose, ensuring safety and facilitating aid delivery. In this regard a rigorous GIS & RS methodology by SWALIM considered nine crucial factors, such as historical flood extent, elevation, slope, topographic wetness index, drainage density, strategic boreholes, settlements, land cover, and roads, to isolate higher grounds suitable for evacuation. The resulting maps show safe areas for evacuation in case of flooding, while exercising discretion considering factors like proximity to schools, healthcare facilities, pest prevalence and any other unforeseen factors

Moderate to heavy rains are expected over Woqooyi Galbeed, Togdheer, Gedo, Bakool and Hiraan regions. Given the general light rainfall activity in the next 7-days, much of the rains are likely to be observed between 28th and 31st October 2023. The spatio-temperal variation of the forecast rainfall is described below: Heavy rainfall of between 100 mm and 150 mm is forecast over several areas in the central parts of Woqooyi Galbeed region and the northern parts of Owdweyne district in Togdheer region, central parts of Gedo region, Bulo Burte district in Hiraan region, and Saakow district in Middle Juba region. Heavy localized rains over these areas are likely to exceed 150 mm with possible cumulative amounts of about 200 mm in Wogooyi Galbeed, northern parts of Owdweyne district in Togdheer region and Bulo Burte in Hiraan region. Very heavy rainfall of above 200 mm is likely over the upper catchments of both Juba and Shabelle Rivers in Ethiopian Highlands. Moderate rainfall of between 50 mm and 100 mm is expected over Baki district in Awdal region, southern parts, Sheikh and Berbera districts in Woqooyi Galbeed region, northern parts of Burco district in Togdheer region, Ceel Afwyene and Ceerigaabo districts in Sanaag region, and Bosasso district in Bari region. Moderate rains are also anticipated over several areas in both Gedo and Bakool regions, Saakow district in Middle Juba region, and Bur Hakaba district in Bay region. In the central parts of the country, rainfall of similar amounts is likely over Gaalkacyo in Mudug region, Cabuudwaaq in Galgaduud region, Bulo Burte district in Hiraan region, and Cadale and Balcad districts in middle Shabelle region. Light rainfall of below 50 mm is likely over the rest of the country except for the following areas where dry conditions are expected to prevail: several areas in Bari, Lower Juba and Middle Shabelle regions, southern parts of Bay region, non-coastal parts of Ceel Dheer district in Galgaduud region, non-coastal parts of Xarardheere district in Mudug region, Garowe district and coastal parts of Eyl district in Nugaal region, and Las Anod district. Temperature Forecast: Elevated temperatures between 35°C and 45°C are likely over Lower Juba, Middle Juba, Lower Shabelle, southern parts of Dinsor and Bur Hakaba districts in Bay region, Jowhar district in Middle Shabelle region, and Sheikh district in Woqooyi Galbeed region. Milder temperatures of between 20°C and 25°C are likely over the highlands in central parts of Sanaag region and northern parts of Bari regions. The rest of the country is expected to observe moderate temperatures between 25°C and 35°C.

Moderate to heavy rainfall of between 50 and 100 mm is anticipated in the northern regions of the country, especially in proximity to Gebiley, Hargeisa, and areas adjacent to the Ethiopian border in Woqooyi Galbeed. Part of Togheer region is expected to experience similar high amount of rainfall especially Sheikh, Odweyn and Buuhoodle districts. In Sanaag region the highest amount of rainfall within the forecast period is expected in Ceel Afweyn and Erigavo districts. Areas around Qardho and Qandala in Bari, as well as Garowe and Burtinle in Nugaal, should anticipate a comparable pattern. Rainfall of comparable amounts is also likely to be observed in many parts of Sool region with chances of heavier storms localized over Xudun, Taleex, and Buuhodle districts. Other parts of the country expected to receive moderate to heavy rainfall include Galkayo and Hobyo in Mudug, Waajid in Bakool, Diinsor in Bay, and Bualle in Middle Juba Region. It is important to point out that rainfall of similarly moderate to heavy amounts is forecast over the Ethiopian highlands. Within Somalia, the heaviest precipitation is projected to occur during the initial three days of the forecast period especially in the northern parts of the country. Light to moderate rainfall is anticipated in Ceel Waaq and Luuq districts in Gedo, Baydhaba in Bay, extensive areas of Bakool, parts of Hiraan particularly Jalalaqsi and Bulo Burti districts, Ceel Buur and Cabudwaaq in Galgaduud, and most parts of western Muduug. The rest of the country is likely to experience scattered light showers throughout the week as per the forecast.

The Food and Agriculture Organization’s Somalia Water and Land Information Management (FAO SWALIM) Project, has finalized the analysis and mapping of the river breakages along the Juba and Shabelle rivers using very high resolution satellite imagery. Breakages identified in the map have been classified into four different categories; Open, Overflow, Canal Flooding Point and Closed with sandbags. A legend/Key for further explanation of the different types of breakages is provided. A total of 170 Open points, 46 Canal flooding points, 152 Overflow points and 29 points closed with sandbags have been identified along the Shabelle River while 26 Open points, 10 Canal flooding points, 16 Overflow points and 14 points closed with sandbags have been identified along the Juba River which require immediate attention. Several other points, which are either potential or temporarily closed with sandbags, have also been identified. The forecast ElNino season is likely to result to enhanced rainfall in Somalia and Ethiopian Highlands with high potential of flooding over the Juba and Shabelle rivers especially where open and potential points have been identified. There is therefore an immediate need to close the open points and reinforce areas where there are weak river embankments. Intervening agencies are advised to take advantage of the current dry period until the rains start and carry out temporary or long term measures to close the river breakages. This will see a reduction of riverine flooding in case of heavy rains and consequently a massive reduction in economic losses to the country.

Juba River: High Risk of Riverine Flooding at Dollow, Luuq, and Bardheere and High Risk of Flash Flooding in Gedo region Shabelle River: High Risk of Flash Flooding in Hiraan, Bay and Bakool Regions and Moderate Risk of Riverine Flooding at Belet Weyne, Bulo Burti and Jowhar Juba River Catchment: Following the moderate to heavy rains, significant fluctuations in water levels have been observed along the Juba River since Wednesday 25th November 2023 when SWALIM issued its weekly bulletin. Today’s (29th October 2023) water levels represent an increase from 3.78 m to 5.46 m at Dollow, an increase from 4.58 m to 6.20 m at Luuq, an increase from 7.10 m to 9.00 m at Bardheere, and a slight decrease 7.40 m to 7.00 m at Bualle. The rains over Bardheere have particularly been heavy with 110.0 mm received on 28th and 86.0 mm received today (29th November 2023) with flash flooding incidences reported. The high flood risk levels have subsequently been surpassed by 46 cm, 20 cm and 80 cm at Dollow, Luuq and Bardheere, respectively. The implication is that the water levels are now just 54 cm, 80 cm and 140 cm below the bankful levels at Dollow, Luuq and Bardheere, respectively. The runoff from the forecast moderate rains over its catchment in the next 24 hours accumulating to about 100 mm in the next three days around the central parts of Gedo region, are likely to sustain the river level rise. The large volume of water upstream is likely to also lead to a rise in the water levels at Bualle to high risk level. There is therefore a high risk of riverine flooding along the entire stretch of Juba River particularly at Dollow, Luuq and Bardheere. There is also a high risk of flash flooding in Gedo region particularly areas bordering Kenya. Shabelle River Catchment:Fluctuations in water levels have also been observed along the Shabelle River. Today’s (29th October 2023) water levels represent an increase from 6.22 m to 6.40 m at Beletweyne, an increase from 5.48 m to 5.76 m at Bulo Burte, and a slight decrease from 4.28 m to 4.20 m at Jowhar. These fluctuations mean that water levels are now just 10 cm, 74 cm and 80 cm below moderate flood risk levels at Beletweyne, Bulo Burte and Jowhar, respectively. Although moderate rains received in Hirshabelle have not been at stations near the main river channel, the runoff from the forecast heavy rains over its catchment in the 24 hours accumulating to over 10 mm in the next three days in some areas in Hiraan, are likely to lead to a sharp rise in the river levels. Similarly heavy rains are likely in some areas in Bakool and Bay region. There is therefore a high risk of flash flooding in low lying and other vulnerable areas in densely populated areas in Hiraan, Bakool and Bay region. There is moderate risk of riverine flooding along the entire stretch of Shabelle River worsening to high risk after three days.

Moderate to heavy rains expected over central and southwestern areas of the country during the coming week. The rains over Gedo and Bakool are likely to be observed in the first part of the forecasting period. The spatiotemporal distribution of the forecast rains is as below. Heavy rainfall of above 100 mm is expected over Bakool, central parts of Gedo, southern parts of Hiraan and isolated areas in northern Galgaduud, localized areas in Galkayo in Mudug and southern parts of Sool. The rainfall over Ceel waaq in Gedo, Tayeeglow in Bakool, western parts of Bulo Burti in Hiraan and western parts of Ceel dheer in Galgaduud is likely to exceed 150 mm. Moderate rainfall of between 50 and 100 mm is expected in Ceel Waaq and Garbahaarey districts in Gedo region, Baydhaba ditricts in Bay, Xudun, Ceel Barde, Tayeeglow districts in Bakool region, western parts of Bulo Burti district, northern parts of BeletWeyne district and western parts Jalalaqsi district in Hiraan. In the central parts of the country, rains of similar amounts are expected over Dhuusamareeb district and southern parts of Cadaado districts in Galgaduud region, Galkayo district, western part of Jariiban district and several isolated areas in Mudug region. Towards the north, comparatively moderate rainfall is also expected over Burtinle district in Nuugal region, southern parts of Qardho district in Bari region, central parts of Taleex districts in Sool region, southern parts of Las Anod, Buuhoodle district in Togheer, Ceel Afweyn town and it’s border areas with Erigavo in Sanaag region. Light rainfall of below 50 mm is anticipated over the rest of the country with the exception of noncoastal areas of Awdal region, Hargeisa and Gebiley districts in Woqooyi Galbeed region, western parts of Bari region particularly over Bosasso district.

Given the recent evolution of warmer than average Sea- Surface Temperatures (SSTs) over the central and eastern equatorial Pacific Ocean, most global climate models have confirmed the presence and persistence of El Niño conditions throughout the October - December 2023 season. Moreover, similar warming of ocean waters near the East African coastline, together with cooling down of the waters near the western Australian coastline, which technically defines a positive Indian Ocean Dipole (IOD), is expected to lead to above normal rains over most parts of East Africa. Somalia’s Deyr (October - December) “short rains” season is associated with the somewhat-faster southward movement of the Inter-Tropical Convergence Zone (ITCZ) which dictates much of the country’s climate. According to ICPAC, the climate outlook for the “Deyr Short Rains’’ season indicates an exceptionally high likelihood (85 %) of enhanced rainfall over southern parts of the country encompassing the catchments of both Juba and Shabelle Rivers where up to 10 consecutive rainy days are probable. Upstream of the river catchments across the Ethiopian border, 4 - 6 consecutive rainy days are expected with higher likelihood of cumulative amounts exceeding 150 mm. In terms of associated risks, the enhanced amounts, more so consecutive rainy days, over Juba and Shabelle River catchments within the country and across the Ethiopian border will likely lead to flooding as from the third week of October. However, the forecast dry conditions over the southern parts of Somalia where the two river catchments lie in the month of September offer some lead time for intervention measures to be put in place to mitigate the potential flood risks. The forecast dry conditions over the agricultural zones in the southern parts of the country in the month of September are also opportune for land preparation. The subsequent rains will likely lead to substantial recharge of water sources, replenished water catchment levels, and improved soil moisture conditions. These will create favorable conditions for grass regeneration, offering fodder for the livestock, and timely crop planting across the agro-pastoral livelihoods.

Rainfall Forecast: There is agreement among several forecast products that light to moderate rains of up to 100 mm is expected over the southwest state and central parts of the country, with some forecasting products anticipating more intense rains. The spatial variation of the consensus-based rainfall forecast is follows: Moderate rainfall of between 50 and 100 mm is expected over isolated areas in Galgaduud, Mudug and Hiraan regions. Specifically, such rains are likely over Ceel Buur district and southern parts of Cabudwaaq district in Galgaduud region, northern parts of Belet Weyne district in Hiran region, and northern parts of Jariiban district in Mudug region. Light rainfall of less than 50 mm is anticipated over Bakool, Hiraan, Galgaduud, Mudug, and Nugal regions. Rains of such intensity are also possible over northern parts of Bay region, southern parts of Bari region, and isolated areas in Sool, Togdheer and Woqqoyi Galbeed regions. Dry conditions are likely in extensive areas in the southern and northern parts of the country. In the north such dry conditions are expected over Awdal region, northeastern parts of Woqooyi Galbeed region, Sanaag and Bari regions. In the south, such dry conditions are likely over Gedo region, coastal parts of Middle Shabelle, Lower Shabelle, Middle Juba, and Lower Juba regions. However, there are chances of cloudiness leading up to light rains over some of these areas.

Review of the 2023 March-April-May (MAM) seasonal rainfall has demonstrated three key points: First, there was an early transition into the Gu (April-May-June) long rains season in Somalia this year. Secondly, above Long Term Mean (LTM) rainfall was received over Puntland and Somaliland and below LTM over South and Central Somalia. Thirdly, the observed rainfall was more in agreement with the forecast over South and Central Somalia and less over Somaliland. The early onset of the generally above-LTAM MAM rainfall led to substantial recharge of water sources, replenished water catchment levels, improved soil moisture conditions, creating favorable conditions for pasture regeneration, offering first line fodder for the livestock. It also favored land preparation and timely crop and fodder planting across the agro-pastoral livelihoods. However, the exceptionally heavy rains over both Shabelle and Juba River catchments in Ethiopian Highlands and the already-soaked soil conditions over the catchments within Somalia led to excessive overbank spillage resulting to devastating floods at Belet Weyne from 9th May, at Bulo Burti from 25th May and at Jalalaqsi from 26th May 2023. Flash floods occassioned by localised rains also occured in several places within Somalia like Bardheere from 23rd March 2023. The floods led to extensive damage to farmlands with earlier-grown crop and fodder and the grassland plains with devastating implications. Nonetheless, the MAM rains generally led to improved food security situation across the country particularly in the case of Somaliland where the observed rains were above LTM. The wetter than average projected rainfall conditions are likely to at least slow the loss of soil moisture and support agricultural and livestock productivity over South and Central Somalia over which below LTM Gu rains were observed. This bulletin presents both qualitative and quantitative review of the temporal and spatial variation of observed-, and verification of the forecast Gu rainfall season.

Moderate rainfall expected over southern coastal regions with light rains predicted over most other parts of Somalia during the forecast period (Map 1). The spatial distribution of the cumulative rainfall amounts is as follows: Moderate rainfall of between 50 and 100 mm is expected over the areas next to the coastline in the southern part of the country. These areas include the eastern and coastal parts of both Badhaadhe and Kismaayo districts, eastern and southern parts of Afmadow district, and the entire Jamaame district in Lower Juba region. Similarly, moderate rains are also likely over Jilib district and the isolated areas in the southern part of Buále district in the Middle Juba region and over several areas in southern and western parts of both Sablaale and Baraawe districts in Lower Shabelle region. Some isolated areas in the north particularly over Eerigavo in Sanaag region are also likely to receive moderate rains. Light rainfall of less than 50 mm is expected over several areas in Afmadow district and the western parts of Badhaadhe and Kismaayo districts in Lower Juba region; Saakow district and northern parts of Buáale district in Middle Juba region; and southern and eastern parts of Baardheere district in Gedo region. Similar rains are likely over Qoryoley, Kurtunwaarey, Marka, Afgooye and Wanla Weyne districts in Lower Shabelle region; several areas in Middle Shabelle and Bay regions; non-coastal areas of Ceel Dheer district in Galgaduud region; and non-coastal areas of both Xaradheere district and southern Hobyo district in Mudug region. In the northern parts of the country, such light rains are likely over southern and central parts of Hargeisa district in Woqooyi Galbeed; several isolated areas in Togdheer region; Xudun and Caynabo districts in Sool region; central border areas of Ceel Afweyne and Ceerigaabo districts, northern parts of both Ceerigaabo and Laasqoray districts in Sanaag region, areas in southern Bossaso district and northeastern parts of Iskushuban district in Bari region. Similarly lighter rains are also likely over the border areas between Garowe and Eyl districts in Nugaal region. Light rains of less than 50 mm are expected over several areas in Afmadow district and the western parts of Badhaadhe and Kismaayo districts in Lower Juba region; Saakow district and northern parts of Buáale district in Middle Juba region; and southern and eastern parts of Baardheere district in Gedo region. Similar rains are likely over Qoryoley, Kurtunwaarey, Marka, Afgooye and Wanla Weyne districts in Lower Shabelle region; several areas in Middle Shabelle and Bay regions; non-coastal areas of Ceel Dheer district in Galgaduud region; and non-coastal areas of both Xaradheere district and southern Hobyo district in Mudug region. In the northern parts of the country, such light rains are likely over southern and central parts of Hargeisa district in Woqooyi Galbeed; several isolated areas in Togdheer region; Xudun and Caynabo districts in Sool region; central border areas of Ceel Afweyne and Ceerigaabo districts, northern parts of both Ceerigaabo and Laasqoray districts in Sanaag region, areas in southern Bossaso district and northeastern parts of Iskushuban district in Bari region. Similarly lighter rains are also likely over the border areas between Garowe and Eyl districts in Nugaal region. Dry conditions are expected over the entire Awdal region and several areas in Gedo, Bakool, Hiraan, Galgaduud, Mudug, Nugaal and Bari regions. In the northern parts of the country, such dry conditions are likely over Berbera district and the northern parts of both Gebiley and Hargeisa districts in Woqooyi Galbeed; northern parts of Ceel Afweyne district, northwestern, southern and eastern parts of Ceerigaabo district and central and southern parts of Laasqoray district in Sanaag region; Caluula, Qandala, Qardho, and Bandarbeyla districts and southern parts of Iskushuban district and northern parts of Bossaso district in Bari region.

Light rainfall is predicted over the southern regions and some isolated areas in the north with dry conditions expected over most parts of Somalia during the forecast period. The spatial patterns of the cumulative rainfall amounts is as follows: Light rainfall of less than 50 mm is expected in the southern regions including: the eastern and coastal parts of both Badhaadhe and Kismaayo districts, eastern and southern parts of Afmadow district, and the entire Jamaame district in Lower Juba region; Jilib district and Buáale district in the Middle Juba region; Diinsoor district and northern border areas of Buur Hakaba and Baydhaba districts in Bay region; Sablaale district and the entire coastal parts of Lower Shabelle region, and areas around Mogadishu in Banadir region. In the northern part of the country, similarly light rains are likely over southern parts of both Gebiley and Hargeisa districts in Woqooyi Galbeed, the northern parts of both Ceerigaabo and Laasqoray districts over Sanaag region and areas bordering the three districts of Qandala, Iskushuban and Caluula in Bari region. Localized light rains in other parts of the country are as shown in the map. Dry conditions are expected over the rest of the country especially the entire Awdal region, many parts of Gedo, Bakool, Hiraan, Galgaduud, Mudug, Nugaal, Sool and Bari regions, northern Woqooyi Galbeed region and southern parts of Sanaag region.

Light rainfall of less than 50 mm is expected the southern regions including: Middle Juba region, the eastern and coastal parts of Lower Juba region, coastal parts of Lower Shabelle and Middle Shabelle regions, south and central parts of Bay region, some areas in eastern parts of Gedo region, and coastal parts of Galgaduud region and Ceel Dheer district in Mudug region. In the northern part of the country, similarly light rains are likely over southern parts of both Gebiley and Hargeisa districts in Woqooyi Galbeed, the northern parts of both Ceerigaabo and Laasqoray districts over Sanaag region and areas bordering Iskushuban and Caluula distrcits in Bari region. Dry conditions are expected over the rest of the country..

Moderate to heavy rainfall expected over isolated parts of northern Somalia with light rains over central and dry conditions over southwestern parts of the country during the forecast period (Map 1). The spatial variation of the cumulative rainfall amounts is as follows: Very heavy rainfall of between 150 m and 200 mm is likely over central and northern parts of Awdal region, southern parts of Ceerigaabo district and western parts of Laasqoray district in Sanaag region, northern parts of Caynabo district in Sool region, Buuhoodle district in Togdheer region, and central parts of Bari region. Heavy rainfall of between 100 mm and 150 mm is anticipated over several areas in Awdal region; northern parts of both Gebiley and Hargeiya districts in Woqooyi Galbeed; northern and southern parts of Togdheer region; several areas in Sool region; several areas in Ceerigaabo district in Sanaag region; northern parts of Qardho district, western parts of Iskushuban district, southern parts of Qandala district and southwestern parts of Caluula district in Bari region; central Garowe district, southern Eyl district and southern parts of Burtinle district in Nugaal region; and Galdogob district in Mudug region.

Similar moderate rainfall is likely over several areas in Middle Shabelle and Lower Shabelle regions. SOMALIA WEEKLY WEATHER FORECAST Valid From 24th to 30th May 2023 Moderate to heavy rainfall expected over isolated parts of northern Somalia with light rains over central and dry conditions over southwestern parts of the country. Light rainfall of less than 50 mm is expected over several areas in Lower Juba region, Middel Juba region, Bay region, eastern parts of Bakool region, Hiraan region, Galgaduud region, Hobyo district in Mudug region, and the coastal areas of Bari region and Berbera district in Woqooyi Galbeed region. Dry conditions are expected in the southwestern parts of the country particularly over Gedo region, Ran Dhuure and Waajid districts and southern parts of Tayeeglow district in Bakool region, and western parts of Saakow district in Middel Juba region. Moderate temperatures of between 24°C and 28°C are expected over several areas in the southern and northern parts of the country. Temperatures as low as 20°C are likely over some areas in the southern parts of Awdal region, southern parts of Woqooyi Galbeed region, Sheikh district in northern Togdheer region, several areas in central Sanaag region (Ceerigaabo) and northern parts of Qandala district in Bari region. The coldest conditions (16°C to 20°C) are forecast over Erigavo in Sanaag region. High temperatures of between 28°C and 32°C are expected in in Hiraan, Galgaduud, mudug, and the coastal areas in the northern part of the country. Similar hot conditions are also likely over Dollow and Luuq districts in Gedo region.

There is a High Risk of Flooding along the Shabelle River at Belet Weyne Moderate rains received in Shabelle River catchment in the Ethiopian highlands and light rains observed in the areas around the Ethiopian borderhave sustained a steady rise in levels along Shabelle River. In the last four days, 40.5 mm of cumulative rainfall has been received at Belet Weyne; 22 mm on 5th, 8.5 mm on 6th and 10 mm on 8th May 2023. The river levels at Belet Weyne steadily increased from 6.38m on 26th April to 7.90m as reported today (8th May 2023). Today’s level is 60 cm above the high flood risk level (7.30 m) and just 40 cm below the bank full (8.30m) threshold. However, at 6.12 m and 3.75 m, the levels at Bulo Burti and Jowhar are 38 cm and 1.25 m below their moderate flood risk thresholds. Since 2nd May 2023 when the high flood risk level was reached at Belet Weyne, any increment in run off occasioned by the moderate rains across the Ethiopian border can potentially lead to river flooding. The information coming from the field indicates that the river flow is hitting the deck of two bridges in Belet Weyne with very high likelihood of river overflowing the banks and causing flooding that might affect Belet Weyne town and its surrounding areas. The Hirshabelle State, Ministry of Agriculture and Irrigation is reported to be distributing pre-positioned sandbags to the vulnerable sites which have begun seeping the water into the town. Although these efforts may mitigate the effects of the flooding, population living in Belet Weyne town and its surrounding areas must still take precautionary measures. The rainfall forecast for the next three days (8th – 10th May) indicates light cumulative rain of about 10 mm over Belet Weyne and of about 20 mm over its catchment in the Ethiopian Highlands. Although there is high risk of flooding along Shabelle River at Belet Weyne currently, river levels are expected to stabilize to below moderate flood risk levels in the coming days given the above light to moderate forecast rainfall conditions.

After the continuous steady rise in its levels at Bulo Burte, the Shabelle River reached its bankful height on Thursday 26th May 2023. On the same day, 58.0 mm of rainfall was received at Bulo Burte station. Subsequent flooding was reported in four villages: Indha Ceel, Bagabeeso, Wadajir and Hagi Buube. The overbank flood water also hindered access in and out of Bulo Burte via the bridge. Downstream in Jalalaqsi, flooding was also reported in Wadajir Horseed, Howl Wadaq and Gumarey on the 27th May 2023). Access through the bridge at Jalalaqsi was also hindered by the flood water. The river levels at both Bulo Burte (Figure 1) and Jalalaqsi have remained at bankful height to date (29th May) with more flood impacts reported. For these four continuous days, the residents have been forced to use boats to gain access to and from both towns. The impacts of the floods (Map 1) that began with Shabelle River bursting its banks on the 9th May 2023 at Belet Weyne have been widespread and devastating. Valuable properties have been lost including farmlands and house destructions. The ensuing population displacement have triggered other social challenges including, unavailability of shelter, food, and clean water for use, increase in water borne diseases, and family disconnection for example. This comes even before the residents of Belet Weyne upstream of Bulo Burte have had a complete return to their normal lives. Having lasted for 15 days in Belet Weyne (9th till 24th May), it is expected that the bankful river levels at Bulo Burte and Jalalaqsi will be sustained for the same period, even though some of the flood water may have been lost through river breakages and overbank spillage in between. Flooding is expected to continue over the next one week with a HIGH RISK OF FLOODS extending to other flood prone areas in Bulo Burte, Jalalaqsi and the adjacent areas. The river level at Jowhar has stagnated below moderate flood risk level (5.0 m) since the beginning of the Gu rains, with today’s level (3.70 m) being far much below its normal mark in this season (4.2 m), but higher than last year level at this time of the year. It is however expected that the high river levels at Bulo Burte will be transmitted to Jowhar within three to five days and eventually to Balcad within the coming week. A HIGH-RISK FLOOD WARNING is therefore foreseen over the next one week for Jowhar and the adjacent areas Since the 58.0 mm rains observed at Bulo Burte on Thursday 26th May, dry conditions have prevailed in the last week over South Central Somalia including the entire stretch of Shabelle River from Belet Weyne to Balcad. Consequently, not much run off will sustain the river levels as the flood wave flows downstream to Balcad. A MODERATE-RISK FLOOD WARNING is therefore foreseen over the next one week for Balcad and the adjacent areas. Therefore, residents of the flooded areas in Bulo Burte and Jalalaqsi are urged to beware of crocodiles that could have escaped the river on to the floodplains. They should also beware of the risks of drowning. In order to prevent water borne diseases, proper hygiene including disinfection measures should be adopted e.g., chlorination of water sources. The residents of areas prone to, but not yet flooded, should move to higher grounds. Residents in these areas who receive this flood warning information should pass it on to family, friends, and neighbors, securing property, and considering assembling an emergency kit with necessary supplies. The residents and authorities should close any open breakages and reinforce the weak river embankments using sandbags provided by the Food and Agriculture Organization (FAO) in partnership with the Hirshabelle Ministry of Humanitarian Affairs and other partners upstream and downstream of Jowhar and Balcad. The residents should also prepare for potential evacuation by identifying safe routes to high grounds and gathering essential items, inform family, friends, and neighbors about the flood warning, secure property and consider assembling an emergency kit with necessary supplies. Residents are also strongly recommended to stay informed through regular bulletin updates at specified times, monitor thorough radio, television and internet for flood warnings.

According to the weekly forecast, moderate to heavy rainfall is expected over several areas in northeastern parts of the country, with light rains over central and southern parts during the forecast period (Map 1). The spatial variation of the cumulative rainfall amounts is as follows: Very heavy rainfall of more than 150 mm is likely to be observed over some areas in Nugal and Bari regions in the northeastern parts of the country. In Bari region, these very heavy rains are likely over the border areas of eastern Qandala and Iskushuban districts and over Bandarbeyla district. In Nugaal region, such very heavy rains are expected over Eyl district and southeastern parts of Garowe district. Over Eyl district, the rains could actually exceed 200mm in areas like Dihlil and Bacad Weyne. Heavy rainfall of between 100 mm and 150 mm is expected over some areas in Nugal and Bari regions in the northeastern parts of the country. Several areas in Bandarbeyla and some areas in eastern parts of Qandala district and northern and eastern parts of Iskushuban, and southern parts of Caluula district in Bari region will observe such heavy rainfall. Similarly heavy rainfall is likely over several areas in Eyl district and eastern parts of Garowe district in Nugaal region. Moderate rainfall of between 50 mm and 100 mm is likely over all other areas in Bari region except Bossaso district and over all areas in Nugaal region except Burtinle district. Moderate rainfall is also expected over Buhoodle district and southern parts of Burco district in Togdheer region, south most parts of Laasqoray district in Sanaag region, eastern parts of Laas Canood and Taleex districts in Sool region, Galdogob district and western parts of Garowe district, and northern parts of Jariiban district in Mudug region. In the central parts of the country, moderate rains are expected in the southern parts of Ceel Dheer district in Galgaduud region and Cadale district in Middle Shabelle region. Rainfall of similar amount is expected over isolated areas in Qoryooley district, Kurtunwaarey district, and southwestern parts of Sablaale district in Lower Sheballe. Similarly moderate rains are likely over northern parts of Jilib district and southern parts of Buáale district, northeastern parts of Kismaayo district and southern parts of Badhaadhe district in Lower Juba region. Light rains of less than 50 mm is expected over several areas in the following regions: Lower Juba, Lower Shabelle, Middle Shabelle, Galgaduud, Mudug, Sool and Togdheer. Light rainfall is also anticipated over Saakow district and northern parts of Buáale district in Middle Juba region, northeastern parts of Baardheere district in Gedo region, south, central and eastern parts of Bay region, and Belet Weyne and Jalalaqsi districts in Hiraan region. In the northern parts of the country, similarly light rainfall is expected over southern and southeastern parts of Sanaag region, northern parts of Bossaso, Qandala and Caluula districts in Bari region, southern parts of Hargeisa and Gebiley districts in Woqooyi Galbeed region, and southern parts of Baki and Borama districts in Awdal region. Dry conditions are expected in the southwestern parts of the country including Bakool region and several areas in Gedo and Hiraan regions, and Ceel Buur district in Galgaduud region. Dry conditions are also likely in the north most parts of the country particularly over Zeylac and Lughaye districts and northern parts of Baki district in Awdal region, Berbera district in Woqooyi Galbeed region, and Sheikh district in Togdheer region. Several areas in the western and northern parts of Sanaag region, as well as the northern coastal strip in Bari region, are also likely to remain dry. Moderate temperatures of between 24°C and 28°C are expected over several areas in the southern and northeastern parts of the country. Temperatures as low as 20°C are likely over some areas in the southern parts of Awdal and Woqooyi Galbeed regions, Sheikh district in northern Togdheer region and Ceerigaabo in Sanaag region and northern parts of Qandala. High temperatures of between 28°C and 32°C are expected in the central regions and northwestern parts of the country.

Since bursting its banks on May 9th, 2023, the Shabelle River’s water level at Belet Weyne (figure 1) has remained at a bankful height of 8.30 meters up to the current date of May 15th. Over the past week Belet Weyne town and its surrounding regions, has witnessed widespread and devastating floods (map 1). These floods have resulted in the destruction of homes, crops, and roads, as well as the displacement of numerous families and have impacted heavily on the transportation network. The river levels at Bulo Burti (figure 2), located about 100 km downstream of Belet Weyne, have shown a consistent increase from 5.74 meters on May 5th to 6.66 meters as of today, May 15th, 2023. The current reading at Bulo Burti (6.66 metres) surpasses the moderate flood risk threshold (put at 6.50 metres) by 16 centimetres . In contrast, at Jowhar, the reading today (3.75 metres) is more than 1 metre below the moderate risk level. However, it is anticipated that the water level at Bulo Burti will reach the high flood risk level in approximately two days, as the flood wave continues its downstream movement from Belet Weyne. Nevertheless, the presence of multiple river breakages downstream of Belet Weyne could mean that some water may escape the channel before reaching Bulo Burti. This scenario reduces the magnitude of flooding in the town compared to the situation witnessed in Belet Weyne. It is important to note that the floodplains located upstream of Bulo Burti remain highly susceptible to flooding. No rainfall has been reported in both Belet Weyne and Bulo Burti over the past week. The weather forecast for the next three days, from May 15th to 17th, 2023, predicts dry conditions across Somalia. Only a light cumulative rainfall of approximately 10 mm is expected much farther upstream in the Ethiopian Highlands, within the Shabelle River catchment area. Despite the absence of recent rainfall, flooding persists in Belet Weyne. There still remains a high risk of flooding in Bulo Burti and the surrounding floodplains. It is crucial for communities residing near riverbanks and low-lying areas to exercise utmost caution and take all necessary precautions to ensure their safety.

Light rainfall is expected over most parts of Somalia with moderate rains over isolated areas in northeastern and dry conditions over southwestern parts of the country during the forecast period (Map 1). The spatial variation of the cumulative rainfall amounts is as follows: Moderate rainfall of between 50 mm and 100 mm is likely over Bari region particularly Iskushuban district, southern parts of Calulla district, eastern parts of Qandala district and southern parts of Bandarbeyle district. Moderate rains are also expected in isolated areas in the northwestern part of Ceerigaabo district in Sanaag region and over the areas on the border between Garowe and Eyl districts in Nugaal region. In the central regions, rains of similar amounts are expected over Cadale district in Middle Shabelle region, southern parts of Ceel Dheer district in Galgaduud region, Qoryooley district and eastern parts of Kurtunwaarey and Baarawe districts in Lower Shabelle region. Light rainfall of less than 50 mm is expected over several areas in the Country with a tendency towards moderate over eastern parts of Bari region, northern parts of Sanaag region, Garowe and Eyl districts in Nugaal region, Ceel District in Galgaduud region, Cadale and Adan Yabaal districts in Middle Shabelle region, and several areas in Lower Shabelle region. Light rains are also expected over Central BeletWeyne district and Jalalaqsi district in Hiraan region. Dry conditions are expected in the southwestern parts of the country particularly over Gedo, Bakool and some parts of Hiraan regions including areas at their border with Bay region. Dry conditions are also likely in Mudug region particularly over Galdogob district, Gaalkacyo district and its border with Hobyo district. In Awdal region, dry conditions are expected over the northern parts of Zeylac and Lughaye districts. Similar conditions are likely over eastern part of Berbera in Woqooyi Galbeed region. Areas in the coastal strip of Bossaso, Qandala and Calulla districts in Bari region area also likely to remain dry. Moderate temperatures of between 24°C and 28°C are expected over several areas in the southern and northeastern parts of the country. Temperatures as low as 20°C are likely over some areas in the southern parts of Aw Woqooyi Galbeed regions, Sheikh district in northern Togdheer region and Ceerigaabo in Sanaag region and northern parts of Qandala district in Bari region. High temperatures of between 28°C and 32°C are expected in in Hiraan, Galgaduud, mudug, Nugaal, and Sool regions, southern and eastern parts of Bari region, and northern parts of both Awdal and Woqooyi Galbeed regions. Similar temperatures copnditions are also likely over Dollow and Luuq districts in Gedo region. Temperatures as high as 36°C are likely over eastern parts of Hobyo district in Mudug region.

For close to two weeks, Belet Weyne town and its surrounding areas have witnessed widespread and devastating floods occasioned by the Shabelle River bursting its banks on the 9th May 2023. The river has remained at a bankful height of 8.30 meters up to the current date of May 22nd. The widespread flooding has resulted to property damage, and population displacement. Over the last two days, the flood water has begun slowly receding from Belet Weyne town and the surrounding areas back into the river, and progressively flow downstream. Subsequently, the river level at Bulo Burte has steadily risen, with today’s (22nd May) level just 13 cm below the high flood risk level. The river level at Jowhar has stagnated below moderate flood risk level (5.0 m) since the beginning of the Gu rain season. Today’s level is 3.75 m and is exactly equal to its normal mark in this season. Although the loss of flood water through overbank spillage between Belet Weyne and Bulo Burte explains the delay in Jowhar river level rise, it is expected that the high river levels at Bulo Burte will be transmitted to Jowhar and eventually to Balcad within the coming week. No rains have been reported in the last week over South Central Somalia including the entire stretch of Shabelle River from Belet Weyne to Balcad. Although light rains to dry conditions are predicted over the coming week, the steady rise in river levels at Bulo Burte poses a HIGH-RISK OF FLOODING in the town and the adjacent areas. A MODERATE RISK OF FLOODING is foreseen in Jowhar and the adjacent areas over the same period. Given the expected loss of water to overbank spillage and breakages along the Shabelle river channel, the risk of flooding reduces as the waters flow downstream to Balcad. Therefore, as the flood water recedes back to the river, residents of Belet Weyne are urged to beware of crocodiles that could have escaped the river on to the floodplains. They should also beware of the risks of drowning. As the residents prepare to relocate back to the previously flooded areas, housing structures need to be assessed for safety. In order to prevent water borne diseases, proper hygiene including disinfection measures such as chlorination of water sources should be adopted. The residents of Bulo Burte should prepare for potential evacuation by identifying safe routes to high grounds and gathering essential items, inform family, friends, and neighbors about the flood warning, secure property and consider assembling an emergency kit with necessary supplies. Residents are also strongly recommended to stay informed through regular bulletin updates at specified times, monitor thorough radio, television and internet for flood warnings. Any open or weak river embankments within Jowhar should be closed and reinforced.
