Somalia Rainfall Forecast - Issued 27 March 2020

The Gu 2020 rains continued to be spread across the country in the last few days with moderate to heavy rains being recorded in the northern regions and light to moderate rains in the southern regions. The rains are yet to start in the central regions of the country. In Somaliland, Lughaye station and the surrounding areas received unusually heavy rains of 102mm on 26 March 2020. Hargeisa recorded 61mm while Gebiley saw a total of 40mm in the same day. The eastern side of Somaliland received light to moderate rains. Parts of Puntland also saw increased rainfall activities in the last three days with many stations recording good rains of between 20mm and 50mm. The southern regions also received good rains of about 20mm-50mm in the last two days. The rains are expected to continue spreading in time and space during the coming weeks with the season expected to record enhanced rains before coming to an end in June 2020. Moderate to heavy rains are expected on 27 March 2020 in the southern regions of Somalia especially in Bay, Bakool and the Juba regions. The cumulative weekly forecast is calling for a reduction of rainfall activities in the northern regions as well as within the Ethiopian highlands. The central regions will remain dry during the forecast period. There has been a slight increase in river levels over the last two days. The river levels are expected to continue increasing gradually with no risk of flooding during the forecast period.

Somalia Rainfall Outlook for Gu 2020

The Gu rains start in March/April and end at different times across Somalia, depending on the north-south movement of the Inter-Tropical Convergence Zone (ITCZ) which is the leading factor for the timing of rainfall in most parts of Africa. Most of the annual rainfall in Somalia (75%) is recorded during the Gu season. As a result, performance of Gu season rainfall is critical both for crop-dependent and livestock-dependent livelihoods across Somalia. According to the consensus climate outlook for the Greater Horn of Africa (GHACOF54) issued in later January 2020, there is a strong possibility (greater likelihood) of March to May 2020 rainfall being average (35%) and above average (35-40%) in most parts of Somalia with likely warmer than usual temperatures across the whole country. This also includes the Ethiopian highlands which contribute significantly to both Juba and Shabelle river flows inside Somalia. Some areas in the far northwestern parts of Somalia, including Awdal, Woqooyi Galbeed and parts of Togdheer regions have higher chances of below normal (40%) to normal (35%) rains. The regional forecast further indicates a likely early start of the season in southern parts of Somalia. On the other hand, a delayed onset of the rainfall is expected over northern parts of the country which is also likely to have prolonged dry periods a few weeks after the start of the season. The expected average to above average rains will boost crop production prospects and replenish pasture and water sources in most parts of Somalia. This comes after a largely favorable rainy season during the October-December 2019 Deyr season, which will contribute to continued recovery among pastoral and agropastoral livelihoods that have previously been adversely affected by recurrent drought conditions. On the downside, riverine flooding along the Juba and Shabelle rivers is likely to occur along the entire channels of the two rivers. This will likely exacerbate the devastation that populations along the two rivers experienced during the 2019 Deyr season. Currently, there are many open river breakages along the two main rivers and this will likely worsen given the expected increase in river levels and consequent flooding during the forthcoming Gu season. SWALIM is in the process of updating the river breakages database which will be shared soon. Flash floods are likely to occur in low lying and built up areas especially in north east and central regions. The expected below normal rains in the far northwestern regions could lead to depletion of pasture and water resources with high likelihood of mild drought conditions towards the middle of the year. Therefore, communities should conserve and use available water resources judiciously. Despite the overall forecast described in the foregoing sections, local and month-to-month variations might occur as the season progresses. Sporadic rainfall events leading to flash floods are likely to occur even in areas with increased likelihood of near to below normal rainfall. Also, dry spells might occur in areas where enhanced rainfall is foreseen. FAO, through SWALIM and its technical partners, will keep updating this forecast for shorter lead time periods and share update information throughout the Gu season

Somalia Tropical Storm Alert - Issued 06 December 2019

Tropical Storm PAWAN expected to lead to winds of medium strength with moderate to heavy rainfall amounts in parts of Somaliland, Puntland and Central regions of Somalia The Tropical Storm (TS) initially named SIX that developed in the northern Indian Ocean has now been assigned the name PAWAN after sustaining a speed of more than 39 miles per hour for two days. The probability of the TS landing in the coastal areas of Puntland has increased from (10% TO 35%) over the last two days and is expected to make a land fall in Nugaal region in the next 24 hours. The influence of PAWAN may start being felt in the coastal areas of Bari, Mudug and Sanaag regions in the next 12 hours where moderate to heavy rains and strong winds are expected. The rains will then spread further inland to many areas within Somaliland, Puntland and central regions on 07 and 08 December 2019. The storm poses an immediate threat to the shipping lane that links Somalia and Gulf states. Other impacts expected include destruction of property and infrastructure including roads, buildings and boats due to the strong winds. Flash floods may also disrupt normal activities along the tropical storm path. Communities living along this areas are advised to take necessary precautions. SWALIM and partners are monitoring the situation and will update you accordingly. For more details on tropical storm tracking you can consult: http://www.tropicalstormrisk.com/ or swalim@fao.org.

Somalia Rainfall Forecast: Issued 09 December 2019

The coastal areas of East Arica have seen an increase in the frequency and strength of tropical storms since 2013, with one or two storms occurring each year since then. This can largely be attributed to climate change and the dynamic weather variation in the East African countries. Climate change studies further suggest an increase of such storms during the 21st Century. More studies are however needed to affirm and predict the storms timely for early action. Last weekend saw a tropical storm make landfall in the north eastern parts of Somalia. The tropical storm named PAWAN was associated with strong winds and heavy rains in some parts of Puntland with most stations recording more than three times their long term mean annual rainfall. For instance, Eyl recorded a total of 260mm while Dangoroyo received 198mm in two days. Other stations that recorded notable amounts include Hasbahale (80mm), Garowe (85mm), Iskushuban (75mm), Qardo (48mm) and Buuhoodle (52mm)among others. The extreme weather conditions led to livestock death as well as destruction of property and infrastructure including roads, buildings and boats. There has also been extensive erosion along the coast and inland. Currently, transport has been disrupted in many areas along the storm path making it difficult to render humanitarian assistance. Standing waters in some areas also pose an immediate danger of water related diseases. Positively, the heavy rains have been beneficial to the eastern parts of Puntland which had remained water stressed for a long period. There will be ground water recharge as well as pasture growth within these areas. The cumulative rainfall forecast for the next three and seven days (Map 1 and 2) indicates light to moderate rainfall in the southern regions and within the Ethiopian highlands. Consequently, this may lead to a further increase in river levels along the Juba and Shabelle Rivers. There remains a high risk of flooding along the Shabelle and moderate risk of flooding along the Juba in the coming week.

Somalia Tropical Storm Alert - Issued 04 December 2019

Tropical Storm SIX expected to cause strong winds and some rains across Puntland and Somaliland A Tropical Storm currently centred in the north Indian Ocean near the coast of Puntland is expected to intensify further and move in a south western direction and cross Mudug coastal areas between Hobyo and Eyl districts on 06 December 2019. Under its influence, moderate to heavy rain are likely to cause flash floods in some regions including Mudug, Nugaal, Bari and Sanaag starting on 06 December 2019. Strong winds associated with the storm may cause destruction of weak structures and fishing gears along the coast. While current forecasts indicate a low probability for the cyclone (10%), if the cyclone makes a landfall, it could have a devastating impact. This is why SWALIM is issuing the Alert. Communities along the coast are advised to take necessary precautions in the coming days. SWALIM and partners are monitoring the situation and will update you accordingly.
