STATUS OF RIVER BREAKAGES ALONG JUBA AND SHABELLE RIVERS - ISSUED MARCH 2024

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. Following the El Niño-induced widespread floods of 2023, there have been an up surge in reported open breakages. A total of 190 Open breakage points, 76 Canal flooding points, 518 River overflow points and 23 points closed with sandbags have been identified along the Shabelle River while 109 Open breakage points, 1 Canal flooding points, 226 River overflow points and 5 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 above average rainfall during the coming Gu season is likely to lead to 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.

Review of Deyr 2023 Rainfall Performance, Jilal Status, Gu Outlook, and Implications on Livelihoods over Somalia

Several key findings have been obtained following a review of the 2023 Deyr (October-November-December) seasonal rainfall. Heavy cumulative rainfall was observed over the south and central parts of the country with a substantial 1,152 mm being recorded in Baidoa in Bay region representing five times of the station’s Long-Term Mean (LTM). The rainfall was even much heavier in Berbera in Wooqoyi Galbeed Region where the amount was 26 times the LTM. The Deyr rains began in early October over parts of Somaliland and central parts of Puntland spreading southwards to Gedo and Bay-Bakool regions. However, there was a sharp end to the Deyr rains particularly over Puntland and Somaliland with no single rainy day observed in Puntland in December. There was more than 30 consecutive dry days in almost all the stations in the country between 1st October and 31st December 2023. The observed rainfall amounts, and the length of wet spells particularly over the Juba and Shabelle River basins within the country were 100% in agreement with the forecast. The onset of Deyr rains across the country was also generally in agreement with the forecast with most of the stations realizing onset within a week of the forecast date.

Somalia Rainfall Forecast – Issued 13 December 2023

Light rainfall of below 50 mm is forecast over some areas in the southern parts of the country in the coming week. These light rains are expected in the earlier part of the forecast week (13th – 15th December) over Badhaadhe, Kismayo and Jamaame districts in Lower Juba region, Ceel Waaq and Belet Xaawo districts in the Gedo region. Other areas expected to receive the light rains are the coastal areas of Jilib district in Middle Juba region, Marca and Kurtunwaarey districts, areas in the Sablaale, Qoryooley, and Barawe districts in Lower Shabelle region, and Baidoa in Bay region. Although moderate in cumulative amounts, the rains over the Lower Juba region are likely to be spread out across the entire week and will therefore be less intense. Moderate rains above 50 mm may be observed in some areas along the southern coastal strip whenever the monsoonal winds blowing parallel to the coastline are accentuated by any elevated East-West oriented terrain. As these monsoonal winds blow southwards across the Gulf, there are also chances of trace amounts of rains over the northern coastal strip including Caluula and Qandala districts in Bari region and Berbera districts in Woqooyi Galbeed region. Dry conditions – The rest of the country is expected to remain dry during the coming week. The model predictions of minimal rainfall amount across the country and the Ethiopian highlands in the month of December signals the end of the Deyr rainy season for Somalia.

Somalia Flood Advisory for Juba and Shabelle Rivers - Issued 20 November 2023

Juba River Moderate to heavy rains received for about two weeks have generated run off that have caused the water levels along the entire Juba River to overflow their riverbanks causing devastating floods which have led to damage to crop lands and road infrastructure rendering them impassable and cutting off access in to and out of towns and other human settlements. Following heavy rains (125.0 mm) recorded yesterday 19th November 2023, the bridge at Luuq has been reportedly overtopped and is at risk of being swept away. The rains over Bardheere have been particularly intense with 108 mm, 35 mm, 96 mm and 58 mm of rain having been observed on 16th, 17th, 19th and 20th November 2023, respectively leading to sweeping away of Budubo bridge. Heavy rains have also been received downstream at Bualle with 71.0 mm being recorded yesterday, 19th November 2023. The light to moderate rainfall forecast over Juba River catchment in Ethiopian Highlands and within the Somalia border in Luuq district of Gedo region will generate runoff of less volume compared to previous week. However, the runoff from the previous moderate to heavy rains and ongoing light to moderate rains will sustain the river overflows and flooding at Dollow and Luuq. Run off from both ongoing and forecast moderate to heavy rains over the Juba River downstream catchment at Bardheere district in Gedo region and parts of Middle Juba region will generate enough runoff leading to increased river overflows and flooding at Bardheere, Saakow, Bualle and Jilib districts. There is therefore SUSTAINED FLOODING along the entire Juba River with INCREASING MAGNITUDE at both Bardheere and downstream at Saakow, Bualle and Jilib. The activated response plans should therefore be sustained along the upper stretch and upscaled downstream at Bardheere, Saakow, Bualle and Jilib. Shabelle River Water levels along the Shabelle River have been steadily increasing in the last three weeks. The river reached bankful level (8.30m) at Belet Weyne on Saturday 11th November 2023. The subsequent riverbank overflow led to massive floods in Belet Weyne town and the surrounding areas leading to damage to buildings, crop lands and rendering the passage into and out of town impassable due to bridge overflows. Based on timely advisories from SWALIM, SoDMA/MoHADM and other partners, the population was safely evacuated to designated higher grounds by the time the floods started. Moderate to heavy rains have been reported along the Shabelle River catchment with 70 mm, 31.8 mm and 29 mm received yesterday, 19th November 2023, at Bulo Burte, Jowhar and Balcad, respectively. The flow of the flood wave downstream coupled with moderate to heavy rains have led to river level rise at Bulo Burte to 32 cm above high flood risk level and only 48 cm below bankful. At Jowhar the level is only 10 cm below moderate risk level and 60 cm to bankful. Even if the flood wave is expected to flow downstream beyond Balcad in the coming days, floods have already been observed as a result of river breakages and flash floods. The light to moderate rainfall forecast over Shabelle River catchment in Ethiopian Highlands and within Hiran region in Somalia will generate runoff of less volume compared to previous week. However, the runoff from the previous moderate to heavy rains and ongoing light to moderate rains will sustain the river overflows and flooding at Belet Weyne and steady river level rise downstream at Bulo Burte, Jalalaqsi, Jowhar and Balcad. There is therefore SUSTAINED FLOODING at Belet Weyne and its environs and HIGH RISK OF FLOODING at Bulo Burte and its environs and PROJECTED HIGH RISK at Jowhar and its environs. The activated response plans should therefore be sustained at Belet Weyne town and the surrounding areas. The evacuation plans should be activated and sustained at Bulo Burte and surrounding areas, while it should be placed on standby at Jowhar and surrounding areas.
