Higher Ground for Flood Evacuation in BeletWeyne and Jowhar Districts
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 like Beletweyne and Jowhar, 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.

Somalia Rainfall Forecast – Issued 27 September 2023
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.

Deyr 2023 Climate Outlook and its Implication on Livelihoods and Programming
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.

Gu 2023 Rainfall Performance Review, Hagaa Outlook and Implications on Livelihoods
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.

Shabelle River Flood Update Issued 15 May 2023
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.
