Somalia’s Gu (April-May-June) is the main wet season in the country, and is critical in supporting agricultural activities and replenishing water and pasture. The season begins as early as the second half of March, at the tail end of the Jilal Season, and the rains intensify in April with the onset progressing north eastwards almost mimicking the south-north progression of the Inter Tropical Convergence Zone (ITCZ) that follows the overhead sun. Gu rainfall cessation occurs in June in most parts of the country, with the north- eastern coastline receiving the least amount of rainfall during this season. According to the recently released Seasonal Climate Forecast issued by IGAD’s Climate Prediction and Applications Centre (ICPAC), there is a 50% likelihood that below normal rainfall (drier than normal conditions) will be observed over most parts of Somalia as is evidenced by the yellow coloration shown in Map 1. Over the northern parts of Middle Shabelle there is greater likelihood (60%) of observing such dry conditions. In the north eastern part of the country, southern Togdheer and Lower Juba there are equal probabilities of below normal, normal and above normal rains over most areas (denoted by white coloration). The above rainfall conditions will be accompanied by warmer than normal surface temperatures (55% likelihood) over much of the country, with increased chance of up to 70% over the northern areas. Drought analysis using SPI have shown moderate multi- season drought conditions in the southwestern Somalia (Gedo and Juba regions) and severe conditions over Sanaag region. Seasonal climate scientists have observed that the poor forecast 2023 Gu rains are comparable to the forecast conditions of the years 2017 and 2021. However, due to the poor predictability of the Gu rain season, the forecast is expected to have high spatial variability. Further, the rainfall forecasts categories vary over regions; 170 mm and 195 mm thresholds are applicable over Somalia. It is worth noting that this forecast is designed for a regional audience that addresses the rainfall totals summed over the three-month period from March to May 2023.

Based on climatology the fourth week of March marks the end of Jilal Season. However this year there has been an early transition into the Gu (April-May-June) long rains season in Somalia. Several parts of the country received moderate rains over the last week with fourteen stations receiving more than 1 mm of rain as is shown in Table 1. The heaviest rains were recorded in Gedo and Bay regions specifically Bardheere (86 mm), Wanle-Wayne (47.3 mm), Luuq (34 mm) and Dollow (23.1 mm). Other stations that recorded over 10 mm of rainfall include Belet Weyne (18 mm) in Hiran, Iskushuban (17 mm) in Bari, Buhoodle (14.7 mm) and Las Anod (10.5 mm) in Sool regions. Continued dry conditions were observed over Awdal, Woqooyi Galbeed, Nugaal, Galgaduud, Bakool, Lower Shabelle and Lower Juba regions. Based on ICPAC’s rainfall forecast for the next seven days (Map 1), it indicates that most parts of the country will receive more than 10 mm of cumulative rainfall. The spread of the cumulative 7 day rainfall amounts are as follows: Light rainfall of between 10 mm and 50 mm are expected over Nugaal, Mudug, Sanaag, southern and eastern Galgaduud, southern parts of Middle Shabelle and Lower Shabelle northern parts of Middle Shabelle, most parts of Gedo and Middle Juba, northern and southeastern parts of Bari, most parts of Sool and central parts of Togdheer and the northern most parts of Woqooyi Galbeed and Awdal. Moderate rainfall of between 50 mm and 150 mm are anticipated over most parts in Lower Juba, Bakool, Hiraan, Woqooyi Galbeed, southeastern Gedo, western parts of Galgaduud, southern Awdal, southern and northern parts of Togdheer and some areas in southwestern and north eastern Bari. Heavy rainfall of over 150 mm anticipated in isolated pockets in the northern Bakool, western Galgaduud, southern Awdal, southwestern and north eastern Bari regions. Moderate temperatures of between 20 °C and 32 °C are expected over most parts of Somalia. However, cold conditions with temperatures less than 20 °C are expected over isolated areas in northern parts of the country particularly the southern parts of Awdal and Woqooyi Galbeed, northwestern Togdheer, central areas in the northern Sanaag and Bari. The heavy rains received over the last few days on both sides of the Ethiopia-Somali border resulted into a sharp rise in river levels along Juba. In Dollow and Luuq stations, Gedo region, the river rose by over 2.5 m within 24 hours between 18th and 20th March. Dollow recorded 2.94 m increase, from 1.94 m on 18th March to 4.88m on 20th March, surpassing the moderate flood risk level. In Luuq the river level rose from 1.96 m to 4.5 m on 19th and 20th March respectively. The levels have slightly reduced in both stations (4.02 m in Dollow and 4.4 m in Luuq) over the last 24 hours. However, with the current forecast more water is expected from the Ethiopian catchment and within Somalia, posing a moderate risk of floods in the upper reaches of the river. Along Shabelle the river levels are still low, with no immediate risk of flooding. The heavy rains observed over Bardheere (86 mm) have been reported to lead to destruction of property and possible loss of life. Based on climatology, these rains represent a wetter than usual conditions. The observed and forecast wet conditions together with the cold conditions (temperatures less than 20 °C) expected over isolated areas in northern parts of the country particularly the southern parts of Awdal and Woqooyi Galbeed, northwestern Togdheer, central areas in the northern Sanaag and Bari are likely to lead to partial recharge of surface water sources and vegetation regeneration giving a glimmer of hope for human and livestock survival. However, high temperatures (about 32 °C) that are forecast to succeed the wet conditions may lead to rapid evaporation thereby leaving no soil water to support vegetation regeneration.

Most parts of south and central Somalia received light to moderate rains over the last one week. Some of the stations that recorded good rainfall amounts in the past week include Bulo Burti 28mm, Balad 19mm, Bardheere 18mm, Luuq 13.5mm and Jowhar 9mm. Widespread rains were also received in Bay, Middle Juba and Lower Juba regions during the week. In Somaliland and Puntland there has been a reduction in rainfall amounts with most stations recording little or no rains. Most regions in Somaliland and the southern parts of the country have experienced pasture regrowth and replenishment of water catchments, and this has led to a reduction in water and pasture stress. However, more rains with good intensity and distribution are required to bring to an end the current drought conditions as the amounts received are still inadequate to alleviate the condition especially in sustaining pasture and crop growth. The central regions of Nugaal, Muudug, Galgaduud and southern parts of Bari region have not received any significant rains and the drought conditions are worsening by day. The cumulative rainfall forecast for the next seven days indicates moderate to heavy rains in the southern regions. The coastal areas of Somaliland and northern Puntland are also expected to receive moderate to heavy rains. Exceptional cumulative rains are foreseen in Awdal especially in areas bordering Djibouti, which may result to flash floods. The central regions and inland areas of Puntland will receive minimal rains during the forecast period. Ethiopian highlands will receive moderate rains during the week in focus. Given the rainfall forecast, the river levels in both Juba and Shebelle are expected to increase slightly towards the end of the week with no risk of flooding.

There was reduced rainfall activities across Somalia over the last one week. Few stations in Somaliland recorded moderate rains, including Las-Dawaco 83.5mm and Dhubato 35mm, while light rains were recorded in Dararweyne 14mm, Lughaye 14mm, Zaila 13mm and Xaji – Salah 12 mm. In Puntland Calulla station recorded 13.4mm. The rest of the country remained either dry or received light showers. As the Deyr season comes to the peak, more rains are required to bring to an end the current drought conditions across Somalia. The rainfall forecast for the next seven days indicates moderate rains across the central and southern regions of Somalia. Parts of Bay and Bakool regions will however receive heavy rains, of up to 100mm cumulatively, within the coming week. The northern parts of Bari and Sanaag regions will also receive heavy rains in the coming week. The rains will be more along the coast of Bari, where cumulatively 150—200mm of rains are expected within the next seven days. The risk of flash floods in these areas is high, resulting from the heavy rains. Awdal, Woqooyi Galbeed, Togheer, Sool and Nugal regions will be mainly dry over the forecast period. Scattered light showers may however be experienced in few places. The upper parts of the Ethiopian highlands are expected to receive light rains, while the lower parts, near the Somalia border, will receive moderate rains in the coming week. River levels along Juba and Shabelle continued to decrease over the last one week. Given the rainfall forecast, the levels in both rivers are expected to increase slightly within the coming week with no risk of flooding.

In the last one week most parts of Somaliland and Puntland remained dry with a few stations recording light rains (Bandar Beyla 19mm, Galkacyo 5mm, Balli Dhiddin 2.4 mm). Little or no rains were recorded in Central Somalia during the same period. The Deyr rains however continued in the southern regions. Some of the stations that have recorded significant rains include Belet-Weyne 65mm, Mataban 61mm, Mahas 36mm, Bulo-Burti 36mm, Bandar-Beyla 19mm, Bualle 18mm and Balcad 12mm. The rains received so far provide an immediate relief to water stress, but more rains are required to bring to an end the current drought conditions across Somalia. The rainfall forecast for the next seven days indicates moderate rains in most parts of southern Somalia while few pockets of the central areas will receive light showers. Similarly, the Shabelle and Juba upper reaches in Ethiopia will receive moderate rains during the forecast period. Pockets of Nugaal, Sool, Sanaag and the coast of Bari are expected to receive light to moderate rains during the same period. The rest of the country is expected to remain dry. River levels along Juba and Shabelle are currently within the average at this time of the year. Given the rainfall forecast, the levels in both rivers are expected to increase slightly within the coming week with no risk of flooding.

Most parts of south and central Somalia have received moderate rains with good distribution over the last one week. In Bay and Bakool regions heavy rains were recorded in Baidoa recorded 144mm, Dinsoor 103.5mm, Quansadheere 66.4mm, Huddur 45.5mm and El barde 41mm over the last one week. Other places in the region where good rains were reported over the last week are Bulo burti 62mm, Bur Hakabar 50mm, Dollow 44.6mm, and Mataban 40mm. Somaliland and Puntland also continued to receive rains over the last one week, but the amounts were reduced compared the rainfall amounts recorded in the previous two weeks. The ongoing rains have contributed to a reduction of water stress, and pasture generation. However, more rains with good intensity and distribution are required to bring to an end the current drought conditions as the amounts received are still inadequate to alleviate the condition. The rains need to be sustained for long period to sustain pasture and crop growth. The cumulative rainfall forecast for the next seven days indicates moderate to heavy rains in most parts of the Juba catchment within Somalia, the lower parts of Galgadud region, and along the Gulf of Aden Coast in Sanaag and Bari regions. The rest of the country is expected to receive scattered light to moderate rains. The Ethiopian highlands will receive heavy rains during the same forecast period. Juba river level has been rising steadily over the last one week, as a result of heavy rains in Ethiopia and within the Somalia. The levels reached high risk levels in Dollow and Bardhere, before starting to go down in the last 2 days. Shabelle river is also high, and above the short term mean. Given the rainfall forecast in the Ethiopian highlands and in Somalia, there is medium risk of flooding in both rivers, especially in sections with weak or open embankments.

The ongoing Karan rains /early kick off of Deyr seasonal rains continued to spread with intensity and in space over the last two weeks in the northern parts of Somalia with some stations recording 50mm to 100mm of cumulative rains. In particular, some of the stations that received good rains in both Puntland and Somaliland include; Las Anod 56mm, Baran 48mm, Burtinle 41mm, Xasbahale 37mm, Aburin 98mm, Dilla 97mm, Quljeed 71mm, Caynabo and Sheikh 48mm. Galckayo, in the central areas, received a total of 56mm while the rest of the country recorded little or no rains. The observed rains have contributed significantly to a reduction of water stress, especially in Hargeisa, Borama and Gebilley districts of Somaliland, but it will take sometime before the ongoing drought situation can be reversed. Other parts of Somaliland remains under severe drought conditions. Equally, immediate relief to water stress was realized in parts of Puntland following the rains; however, more rains with good intensity and distribution are required to improve the current drought conditions. The central and southern regions continue to experience severe drought conditions. The cumulative rainfall forecast for the next seven days indicates moderate to heavy rains in Somaliland and Puntland. Most parts of the south and central areas will record light to moderate rains during the forecast period and areas bordering Ethiopia and Kenya will receive scattered showers. The upper parts of the Ethiopian highlands will also receive good rains. River levels along Juba and Shabelle rivers are currently below the short-term average. Given the rainfall forecast in the Ethiopian highlands, the river levels are expected to increase from the second week of October. Users are advised that this is a forecast, and there may be discrepancies between estimates and actual amounts of rainfall received. Information on the forecast and observed river levels is updated daily and can be found on this link: http://frrims.faoswalim.org.

The Deyr rains continued to spread in time and space over the last few days with many places in Somaliland and Puntland, especially those bordering Ethiopia recording significant rainfall amounts. Notably, some of the stations where good rains were recorded over the last one week include Las Anod 167mm, Balidhig 40.5mm, Xasbahale 83.0 mm, Burtinle 39.0 mm and Eyl 74.0 mm. Wanle Wayne, in the central Somalia received a total of 9.0 mm, while the rest of the region recorded little or no rains. The observed rains have provided immediate relief to water stress in these areas, temporarily improving the drought conditions. However, more rains with good intensity and distribution are required to bring to an end the current drought conditions. The central and southern regions of Somalia are yet to receive any substantial rainfall, and severe drought conditions prevail. The cumulative rainfall forecast for the next seven days indicates heavy rains in Somaliland and Puntland with the highest amounts expected in areas close to the Ethiopian border. Moderate rains are expected in most parts of the South and Central save for Gedo region and areas bordering Kenya which are expected to receive little or no rains. Given the rainfall experienced in the Ethiopian highlands during the last two weeks and rainfall forecast for the coming week, the Juba and Shabelle river levels are expected to continue rising over the forecast period.

The last one week has been characterized by heavy rains in many parts of Somaliland and Puntland. As a result of the heavy rains Qardho experienced severe floods on 23rd October that led to destruction of infrastructure and property. Las Anod recorded a total of 104.0 mm in one day; while in the same week Caynabo received 91.0mm, Elafweyn 77.5mm, Dhahar 71.0mm, Eyl 74.0mm, Salaxley 63.5mm, Balidhiig 61mm, Las Dacawo 57mm, Talleh 48mm, Galkayo 48.0mm, Xasbahale 42.0mm, Burtinle 39.0mm, Dhubbato 38.0mm and Sheikh 36.0mm. Moderate rains were recorded in few stations in the central and southern regions, including Wanle Wayne 18.8mm and Mahas 15.5mm. Large parts of this region recorded light or no rains over the past one week. More rains with good intensity and distribution are required across the country to bring to an end the current drought conditions. The rains need to be sustained for long period, and more spatially distributed to sustain pasture and crop growth. The cumulative rainfall forecast for the next seven days indicates heavy rains in Togdheer, Sool, Hiraan, Bakool and Galgaduud regions. Moderate rains are expected in the rest of the country save for the coastal areas of Bari region, and parts of Awdal region that may receive little or no rains. Middle and Lower Juba areas near the Kenyan border will also receive light rains, same with the coastal areas of Lower Shabelle region. The Ethiopian highlands are expected to receive heavy rains. Shabelle river level is currently high and given the rainfall forecast in the Ethiopian highlands, flooding may occur in sections with weak or open embankments. The risk is minimal along Juba river, as current levels are below average for this period.

Over the last two weeks, light to moderate rains have been reported in parts of Somalia, marking the onset of Deyr season. However, many parts of the country remain hot and dry. The western parts of Somaliland continued to receive good rains over the last two weeks. Some stations that recorded good rains over this period include Amoud 162mm, Qulujeed 100mm, Aburin 84mm, Sheikh 81mm and Magalo-Cad 68mm. Bari and Nugaal Regions of Puntland also received scattered rains, with Baran station recording the highest amount of 132mm over the past two weeks. Few areas in the central and southern regions of Somalia received light rains. The rains received so far are however of minimal impact, and the country continues to experience severe drought conditions. The rains are expected to spread in time and space during the coming weeks. The cumulative rainfall forecast for the next seven days indicates scattered light rains across the country. Few pockets of moderate rains are expected in Togdheere, Sool and Sanaag Regions. Galgadud, Bakool and Lower Juba will also receive moderate rains in few places. The Ethiopian highlands where Juba and Shabelle rivers originate will have moderate to high rains during the forecast period. River levels along Shabelle and Juba, and which have been rising since beginning of September have slightly dropped over the last one week. The levels are currently within the short term mean for this period.
