Somalia Rainfall Forecast 03-11-2015
Light rains spread across many southern and central parts of Somalia are expected in the next three days. The northern parts of the country are expected to receive moderate rains over the same period, with few pockets in Togdheer and Bari regions experiencing high rainfall of up to 100mm which can lead to flash floods. The upper catchment of the Shabelle River in Ethiopia will receive high rains as well, which translates to increase in river levels later in the week.

Flood Watch Bulletin 27-10-2015
The rainfall forecast for the coming week indicates heavy rains within the two basins both inside Somalia and Ethiopian highlands. Heavy rains are also expected in Banadir, Galgaduud, Mudug and parts of Nugaal, sool, Sanaag and Toghdheer regions with a possibility of flash floods in these areas.
River levels in the middle and lower reaches of Shabelle River are currently at full crest in some sections of the river.
Given the rainfall forecast and the current river levels, there is a high risk level of flooding along the middle and lower reaches of Shabelle. A Moderate risk of flooding is foreseen in the lower reaches of Juba River especially in locations where there exists open river breakages.

W-26 Hydrogeological Study in Ceel Waaq District, Gedo Region, Somalia
The study demonstrates the validity of using Landsat imagery to delineate fracture zones, hence areas of relatively higher groundwater potential. Recharge water is channeled along regional fractures that enhance hydraulic connectivity hence higher fluxes along these lineaments. The identification of the nearest lineaments to each village was done with the help of automatically generated lineaments and manual tracing on satellite imagery, to select potential geophysical survey sites within a 2-kilometer radius of each village.

The El nino phenomenon Infograph
An El Niño state occurs when the central and eastern equatorial Pacific sea-surface temperatures (SSTs) are substantially higher than usual. The National Oceanic and Atmospheric Administration (NOAA) defines an El Niño event when the NIÑO 3.4 area has sea-surface temperatures at least 0.5 ºC higher than normal for five consecutive three-month-averaged periods. During the last 25 years, Somalia has been affected by six moderate-to-strong El Niño events: 1991-2, 1994-5, 1997-8, 2002-3, 2006-7, and 2009-10 in which floods of different magnitudes were reported. The 1997/98 was the strongest followed by that of 2006.

Deyr 2015 Rainfall Outlook
The Greater Horn of Africa Climate Outlook Forum (GHACOF) has confirmed that El Nino conditions have intensified and will affect the region during the September to December rainy season. The El Nino event is likely to lead to a wetter than normal Deyr season in parts of the country.
This is a probabilistic forecast designed for a regional audience that addresses the cumulative rainfall forecast over the four‐month period from (September to December 2015). The rainfall pattern may vary from place to place with the areas expected to receive high rains experiencing periods of dry spells and areas expected to receive low rains experiencing heavy storms.

Status of River Breakages - Juba - August 2015
The Deyr 2015 (September to December) rainfall forecast points towards enhanced rainfall activities due to the foreseen El Nino event taking place in the region. The foreseen enhanced rains are likely to exacerbate the situation. Consequently, poor river embankments are likely to cause flooding, there are currently 47 open points along the Juba. Several other points with potential of breaking have been identified.
