Somalia Rainfall Forecast – Issued 13 April 2021

The Gu rains which started in the southern parts of Somalia continued to spread over the last three days. Some stations in the region have so far recorded light to moderate rains, while others remain dry since the onset of the season, in the first week of April. In the northern parts of the country the season has not yet started, with no rains recorded across the stations. The cumulative rainfall forecast for this week indicates spread of the rains to the northern parts of the country. Light to moderate rains are expected over the southern and northern parts of the country, while the central regions remains dry over the same period. Some parts of Awdal Region may experience high localized rains of up to 100mm, according to the forecast. In the Ethiopian highland, whose rainfall is largely responsible for increase in river flow along the Juba and Shabelle Rivers inside Somalia, moderate to high rainfall is foreseen in the coming one week. River levels along the Shabelle have increased slightly at Belet Weyne over the last 2 days, but remains low and below the normal for this period of the year. Along Juba River the levels are within normal for this period. Given the rainfall forecast, a slight increase in the levels for both rivers is expected with no risk of flooding over the next seven days.

Somalia Gu 2021 Rainfall Forecast and Weather Update

Equal chances of average, enhanced and depressed rains expected during the Gu 2021 season. According to the March to May 2021 seasonal forecast issued by IGAD Climate Prediction and Application Center (ICPAC) during the Greater Horn of Africa Climate Outlook Forum (GHACOF57), there are equal chances of receiving either above average, average or below average rainfall amounts in most parts of Somalia. The three-month outlook favours a similar situation for the eastern Ethiopian highlands which are responsible for most of the flow in the Juba and Shabelle rivers in Somalia. A few pockets in Puntland within Bari and Sanaag regions will receive enhanced rains during the season. Warmer than usual season is expected in the northern areas while relatively cooler conditions are likely to occur in the southern parts of Somalia. In contrast, forecast from FEWS NET’s science partners (NOAA/CPC, NASA/GFSC and CHC) indicates: (1) cumulative rainfall during the March-June 2021 long rains/Gu season in Somalia is most likely to be below-average in Somalia, (2) Gu season rainfall onset is likely to be poor or delayed, and (3) there is an increased likelihood that the rainfall amounts will be widely below average in May, which may signal an earlier-than-normal end of the rainfall season. Given the above seasonal rainfall forecast, all sectors should be prepared for both best and worst case scenarios. However, a pessimistic forecast should be considered for humanitarian response planning during Gu 2021. SWALIM and partners will closely monitor the situation and provide shorter timescale forecasts throughout the season.  Sunny and dry weather conditions characterized by higher than average daytime temperatures prevailed over most parts of the country since December 2020. The unusually dry period is as a result of the poor Deyr 2020 rainfall season in many parts of the country. The areas in northern and central Somalia worst affected by poor rainfall during the 2020 Deyr (October-December) season are currently experiencing mild to moderate drought conditions, leading to water shortages and high water prices. The local authorities in these areas have initiated water tracking activities with Sanaag, Bari, Nuugal and Mudug areas being worst affected by the water shortage. The Juba and Shabelle river levels are very low at this time of the year. Parts of the middle and lower reaches of the Shabelle River are reportedly dry leaving insufficient flow to support irrigation along the river. Whether this drought condition deteriorates to a full-fledged drought or improves will depend on the timeliness, amount and distribution of the forthcoming Gu season rainfall. A more detailed downscaled outlook will be released in the coming days by national inter-ministerial meteorological working group (IMMWG) of Somalia. The downscaled outlook is expected to cover sectorial impacts and advisories for the coming season.

Status of River Breakages Along Juba and Shabelle Rivers - Issued March 2021

In the recent years, floods have prevailed in Somalia hampering both social and economic development. Rainfall intensity in the Ethiopian highlands triggered riverine flooding along the Juba and Shabelle rivers in the last three consecutive years. With climate models projecting an increase of rainfall intensities in the region in the coming yeras, flood events will therefore continue to take place if nothing is done. The presence of open and weak river banks contributes significantly to flooding along these two major rivers. It is therefore of paramount importance to try and reduce or rather prevent these losses due to flood events. With the objective of identifying locations and dimensions of the open and weak points along the Juba and Shabelle Rivers, SWALIM has carried out an assessment using very high resolution (VHR) satellite images. The activity aimed to ascertain the existence of such points and share with intervening agencies and other partners to inform decisions for closure of the points which would see a reduction of flood impacts along the river. Along the Juba River, 46 open points, 8 overflows and another 65 potential overflows were identified. The Juba River assessment also identified over 100 potential breakage points. Further, the team have identified 57 open points, 225 overflows and 74 potential overflows along the Shabelle River. These points need immediate closure or reinforcement before the Gu rainy season which is expected to start in Mid-April 2021. It is worth noting that due to limited availability of VHR images, there has been a delay in completing the assessment of Shabelle River breakages. FAO SWALIM is in the process of procuring images to cover the assessment gap and partners will be notified once the finalized product is ready. SWALIM is pleased to share with you the status of open river points maps along the Juba and Shabelle which can be downloaded from the download links.

Somalia Drought Update – Issued March 2021

Many parts of Somalia are currently experiencing drought conditions, triggered by below average 2020 Deyr (October-December) season rainfall which was characterized by depressed rains with poor spatial and temporal distributions and harsh conditions during the typically dry Jiaall (January-March) season. The worst affected regions include Lower Juba, Middle Juba, Gedo, Mudug, Nuugal, Bari, Toghdheer and Sool which are currently experiencing severe water shortage for domestic use, water for livestock as well as agricultural production. Water and pasture resources are getting depleted in most of the affected pastoral areas leading to abnormal migration of livestock and communities. Currently, water levels in the Juba river are within the normal range, while water levels along Shabelle river are slightly below average. The levels in both rivers are expected to decrease further as no rains are foreseen in the coming two weeks. Drought conditions could worsen if the 2021 Gu (April-June) season rainfall is delayed and/or performs poorly as some forecasts indicate.

Status and Impacts of Open River Points along the Shabelle River in Jowhar, Balcad and Afgooye Districts

A recent flood analysis by SWALIM indicates that there has been an increase in flood frequency and intensity in the last 10 years along the riverine areas of Juba and Shabelle Rivers in Somalia. Recognizing the recurrent flooding along the Shabelle River in the last few years, SWALIM undertook a field survey in Jowhar, Balcad and Afgooye districts. The objective of the survey was to map existing open and weak river embankments in the three districts. We are pleased to share with you the status and impacts of open river points along the Shabelle River in Jowhar, Balcad and Afgooye Districts bulletin and related annexes.

Somalia Rainfall Forecast - Issued: 02 November 2020

There has been a significant decline of rainfall amounts across Somalia over the last week. In the north western regions of Awdal, Wooqoyi Galbeed and Toghdheer, a prolonged dry period has been observed since the last week of September 2020. Most stations in these regions recorded little or no rainfall during the month of October 2020. Similarly, parts of Puntland have not received any rains since the first week of October. There also remains a significant rainfall deficit in most parts of the southern regions and especially the Jubas and Lower Shabelle. The last week saw a reduction of river levels along the Shabelle River. Currently, levels are within normal in Belet Weyne and Bulo Burti districts while the mid and lower reaches are still at high levels. In Agfooye, the levels are at full capacity and most parts of the riverine areas remain inundated with massive displacement being reported in the area. River levels along the Juba increased sharply in the last one week reaching alarming levels in Bardheere. This was due to heavy rains in the upper reaches of the Ethiopian side which also led to river flooding in Dollow. The last three days have however seen a reduction of the levels along the channel. The cumulative rainfall forecast for this week suggests a significant reduction of rainfall amounts across the country with light rains along the southern coastal areas. Little or no rainfall is foreseen in the Ethiopian highlands. This will subsequently lead to a decrease in river levels especially along the Shabelle river. Given the rainfall forecast and current situation along the two rivers, flooding is likely to persist in Lower Shabelle riverine areas. There is no risk of flooding foreseen along the Juba River. There is however a great concern of moisture deficits across the country especially in the rain fed agricultural areas of the southern regions. Drought conditions are foreseen if the trend continues.

Tropical Storm Update - Issued: 24 November 2020

Tropical Storm GATI weakened leaving a trail of destruction in parts of Bari and Sanaag regions The tropical storm GATI has weakened further and is moving westwards with a speed of 7KPH. It is expected to dissipate in the next 12 hours. The storm left behind a significant physical and economic damage especially in Bari region. More than 700 houses were destroyed, several boats and fishing gears damaged and loss of a large number of livestock. This has led to loss of livelihood for most families and may take time and huge financial input to replace the loss. There was a reduction of rainfall amounts and wind speeds in the last 24 hours in many areas along the storm path. This trend is expected to continue as the storm gets weaker and the situation will stabilize thereafter. The sea conditions are still rough over the coastal areas of Puntland and Somaliland and fishermen are advised not to venture into fishing operations for today. The storm impacts will continue to be experienced today in Sanaag and Woqooyi Galbeed coastal areas but with lesser magnitude compared to what was experienced Bari in the last two days. The rainfall forecast for Somaliland and Puntland is calling for moderate rains in the next couple of days and a reduction towards the end of the week. The Ethiopian highland and southern parts of the country are also expected to experience moderate to heavy rains in the course of the week. Given the three days rainfall forecast, flash floods may occur in Toghdheer, Sool, Galgaduud and Mudug regions within the areas neighboring Ethiopia.

Tropical Storm Update - Issued: 25 November 2020

Tropical Storm GATI dissipated leaving a trail of destruction in parts of Bari and Sanaag regions The tropical storm GATI that developed on 22 November and intensified in the following day on 23 November 2020 lost its intensity and dissipated in the last 12 hours. However, light to moderate rains associated with the storm passage will continue to be felt until end of day tomorrow 26 November 2020. Today, a few places in Somaliland recorded moderate rains while others continue to receive light showers. The impacts of the storm also continue to be felt by communities living along its path. This may last for a long time as most livelihoods were disrupted. The sea conditions are still rough over the coastal areas of Wooqoyi Galbeed and Awdal regions of Somaliland and fishermen in these areas are advised not to venture into fishing operations for today. Sea water in Bari and Sanaag coastal areas started to stabilize and will be back to normal by tomorrow. Fishermen in these areas are advised to take caution as well. The rainfall forecast for Awdal and Wooqoyi Galbeed regions in Somaliland is calling for moderate rains in the next three days including today. No rains are expected in Puntland safe for a few pockets in the coastal areas that may record light rains during the same period. The Ethiopian highland and southern parts of the country are also expected to experience moderate to heavy rains in the course of the week. Given the three days rainfall forecast and the reduction of rainfall activities in the last 24 hours there is a moderate to low risk of flash floods in the southern parts of Togdheer region. No risk of flooding is foreseen Puntland.

Somalia Rainfall Forecast - Issued: 27 November 2020

The last few days saw increased rainfall amounts in parts of Somaliland and Puntland which were associated with the passage of Tropical Storm GATI. Some stations like Bossaso recorded 128 mm surpassing its annual average rainfall (50mm) in just a single day on 23 November 2020. Caalulla which had not received any rains in the year since March also saw significant rains of 76 mm on the same day. Other stations within the coastal areas of Bari, Sanaag, Woqooyi Galbeed and Adwal regions also recorded moderate to heavy rains. The storm which was characterized by strong winds and heavy rains led to loss of human lives, livestock death and destruction of properties. On the other hand, the unusual heavy rains in the area also led to immediate and short term recharge of subsurface water sources and pasture growth especially in Somaliland which has had a prolonged dry period since September 2020. However, these rains are not sufficient to cater the water deficit in the area. The three and seven days cumulated rainfall forecast (Map 1 &2) is pointing towards light rains in scattered areas in southern regions and moderate rains within in Lower Juba. Light rains are foreseen in the Ethiopian highlands during the forecast week. Hot and dry conditions will persist in Somaliland and Puntland with the rainy season coming to an end. River levels along the Juba and Shabelle basins remain within the normal ranges with no risk of flooding given the rainfall forecast. There remains a great concern in Somaliland and a few other places in the country due to insufficient rains during the Deyr season. With no more rains expected until the next rainy season in April 2021, the condition could deteriorate further towards a drought situation. This is confirmed further by the current climate models confirming a higher certainty of La Niña conditions persisting through March 2021. SWALIM and other technical partners are on the lookout of such developments.
