The forecast for the next three days points towards increased rains in the Shabelle basin inside Somalia, the Ethiopian highlands as well as the central parts of the country . The North western parts may also record moderate rains while the lower parts of Juba and north eastern parts may receive light rains within the same period.

The Deyr 2015 rains have started in some parts of Somalia. The upper parts of the Ethiopian highlands, Lower Juba region and north eastern parts of Somalia are expected to receive light to moderate rains within the next three days. Other parts of Somalia and the lower parts of the Ethiopian highland will receive little or no rains during the same period.

Heavy rains are expected to continue in the Ethiopian highlands and most parts of Somalia except Awdal, Bari, Nugaal and Mudug regions. Toghdheer, Bay and Lower Shabelle regions are expected to receive the highest amounts which may lead to flash floods and river floods in respective areas.

The Deyr 2015 rainy season started well in many parts of Somalia and has been increasing in space and intensity over the past few days within the Juba and Shabelle river basins both in Somalia and in the Ethiopian highlands. River levels in the upstream stations along the Juba and Shabelle (Luuq and Belet Weyne respectively) continued to increase over the last week. The levels in the middle and lower reaches of Shabelle River are currently high. Given the current river levels and the current rainfall forecast (which indicates heavy rains within the Shabelle basin both in Somalia and the Ethiopian highlands; moderate rains expected in the Juba basin inside Somalia; heavy rains in the highlands and the coastal areas of Banadir, Middle Shabelle and Galgaduud), there is a moderate flood risk level along the middle and lower reaches of Shabelle while there is no foreseen risk of flooding along the Juba in the coming week.

The Deyr 2015 rains have started in some parts of Somalia. In the coming three days, most parts of central regions are expected to receive rainfall totals of up to 20mm while the rest of the country will receive either little or no rains during the same period.

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 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.

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.

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 21 open points along the Shabelle river. Several other points with potential of breaking have been identified as shown in this map.

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.
