    Summary
    Moderate Gu rains fell across most of southern and northwestern Somalia, some parts of the Northeast, and localized western areas in the central regions from May 1 to 10 (Figure 1). In parts of Bakool, Sool, Nugal Regions, eastern Addun Pastoral livelihood zone, and the cowpea belt in the central regions, localized light to moderate rains were reported. In Bari Region, most parts of Sanaag, northern Gedo, Coastal Deeh Pastoral livelihood zone in the central regions, and Guban Pastoral livelihood zone in the Northwest, little or no rain was recorded.

    Situation

    In the Northwest, the Hawd, West Golis Pastoral and Northwest Agropastoral livelihood zones in Awdal, Togdheer, and Woqooyi Galbeed Regions received moderate to heavy rainfall. Parts of the Nugal Valley, Hawd Pastoral livelihood zone in Sool Region, and localized areas of East Golis Pastoral livelihood zone in Sanaag Region received moderate to light rains. The remaining areas of the Northwest remained mostly dry.

    In Northeast, satellite-derived rainfall estimates (RFE2) showed light showers in most areas, but field information reported little to no rain in Bari Region, Nugal Valley Pastoral livelihood zone, and most parts of Coastal Deeh Pastoral livelihood zone. However, the Hawd and western part of Addun Pastoral livelihood zone in Nugal Region and northern Mudug Region received moderate rains with average distribution. These rains have eased the water stress and halted water trucking. However, impacts on pasture availability are not yet widespread, but they will be more widely observed if near normal to normal rain falls for the rest of the month, promoting normal, opportunistic livestock migration.

    In the central regions, localized, light to moderate rain fell in some parts of the cowpea belt, the Hawd, and Addun Pastoral livelihood zone in both Galgaduud and southern Mudug as well as most pastoral areas in Hiraan. However, there was far less rainfall in Coastal Deeh Pastoral livelihood zone, adjacent areas of Addun Pastoral, and in Hiraan Riverine livelihood zone. These rains are likely to support the further development of cowpeas and sorghum, and will likely increase water and pasture availability in rainfed areas. In Hiraan Region, rain gauges in Beletweyne, Jalalaqsi, and Halgan in Buloburte District recorded 39 millimeters (mm), 44 mm, and 41 mm, respectively, with two to three rainy days. Rains have already significantly improved pasture conditions and replenished water sources in many areas.

    In most crop-growing areas of the South, moderate to above average amounts of rain with average coverage have been reported. For example, rain gauges in Baidoa, Bardale, Dinsor, and Qansahdhere recorded 54 mm, 28 mm, 86 mm, and 115 mm of rainfall, respectively, with three to four rainy days in each location. Janaale and Afgoye in Lower Shabelle recorded 25 mm and 35 mm, respectively, with two to five rainy days. However, northern Gedo, Coastal Deeh Pastoral livelihood zone in the South, and adjacent agropastoral areas in Lower Juba remained dry.  These rains rejuvenated crops, pasture, and browse and increased water availability in both pastoral and agropastoral areas. As a result, body conditions and production for all livestock species have improved. Torrential rainfall fell in Sabalale district in Lower Shabelle and Bardhere District in Gedo,  causing flash floods that damaged  both houses and cropped land.       However, May 11 to 20 rainfall wasbelow the 1983 to 2011 average (African Rainfall Climatology 2 (ARC2)).  Rainfall was below normal in northern Gedo, Rabdhurre and Elbarde Districts in Bakool, and

    The Normalized Difference Vegetation Index (NDVI) for May 1 to 10 shows below average vegetation levels in most parts of the country due to the effects persistent dry weather in April. However, improved vegetation conditions were observed in most parts of Awdal, Bay, the Jubas, Woqooyi Galbeed, southern Gedo, and parts of Lower Shabelle due to the effect of some rain in April followed by moderate rains in the first part of May (Figure 3). The May 14 to 20 forecast is for increased rainfall in most parts of the northern regions of Awdal, Bari, Nugal, Sool, Sanaag, Togdheer, and Woqooyi Galbeed (Figure 4). In addition, most of the central regions of Mudug and Galgaduud as well as the southern regions of Bay, Bakool, Hiraan, Gedo, Lower and Middle Shabelle, Lower and Middle Juba, and southern Galgaduud will likely have light to moderate rain of between five and 50 mm. Awdal Region in the Northwest is likely to be dry during the forecast period (Figure 4).

    FEWS NET’s Seasonal Monitor reports are produced for Central America and the Caribbean, West Africa, East Africa, Central Asia, and Somalia every 10-to-30 days during the region’s respective rainy season(s). Seasonal Monitors report updates on weather events (e.g., rainfall patterns) and associated impacts on ground conditions (e.g., cropping conditions, pasture and water availability), as well as the short-term rainfall forecast.
