Karan rains persisted in the Northwest regions, while Hagaa showers were confined in the coastal regions of Shebelle’s, Juba’s and parts of Bay. Northeastern regions also recieved moderate to heavy rainfall during the first two dekads of September whereas Central regions remained largely dry. Field reports indicate localized rainfall in Bakool, Gedo and Hiran.

The rain gauge stations that recorded above average rains include: Borama (82mm),
Gebiley (92mm), Dhubato (143mm), Erigavo (188mm), Elafweyn(96mm), Qardo (66mm) and Ishkushuban (51mm) [Table 1 and Map 1]. The Shabelle River level has increased considerably in September but remained below flood risk level.

Satellite derived rainfall estimates (RFE) indicate prevalence of Karan rains in Northwest and Gu seasonal rains in the south as well as in Northeast (Map 2-5).

The Normalized Difference Vegetation Index (NDVI) for September 2017 suggests deterioration of vegetation conditions in large areas of the country. The NDVI profiles (Page 3 and 4) mostly show negative trends especially in the month of September across the country. Areas with large vegetation deficits: small pockets in pastoral livelihood of Northwest and central (Sool, Sanaag, Mudug and Galgadud), Maize agropastoral livelihood zone of Lower Shabelle and Middle Shabelle, small to large areas in Bay/Bakool agropastoral and large areas in pastoral livelihoods of Lower Juba. Additionally, field reports in Central indicate distressed browse conditions due to drought conditions.

The Karan rains in September have largely benefitted present sorghum and maize crops, improved pasture, browse regeneration and replenished water sources in most of the agropastoral areas in Northwest (W.Galbeed and Awdal regions). Additionally, in the South, rains in September have slightly improved pasture and replenished some traditional water catchments, further improving prospects or early planting of crops in riverine and agropastoral livelihoods.

Reported ongoing agricultural activities in the South include; land preparation, de-silting of irrigation canals and solidification of river embankments, and flooding of Desheks in preparation for Deyr (October-December) season planting. In Central livestock and water conditions are extremely poor leading to drought related livestock deaths in parts of Hawd Livelihood zone (Dhusamareb, Abudwak), Addun (Adado) and coastal livelihoods of Hobyo district.
