Rainfall expected to increase, signaling the full onset of the October to December seasonal rains
• The onset of the October to December seasonal rains during the first three weeks of October was generally erratic in terms of intensity and spatial and temporal distribution across East Africa.
The start of the Deyr was delayed one to three weeks in Somalia and parts of Ethiopia, most notably in the agropastoral livelihood zones of southern Somalia.
Northern seasonal rains forecast to typically subside and likely timely onset for October rains
The June to September seasonal rains gradually subsided in late September, marking the cessation of persistent well aboveaverage rainfall amounts across most of the northern sector, which led to widespread flooding in Sudan. However, some areas of the region experienced significant cumulative seasonal deficits, including some central areas of Ethiopia, eastern and central South Sudan, and northern and eastern Uganda.
During the month of August, Sudan continued to receive significantly above-average rainfall, which caused additional widespread flooding, fatalities, livestock and crop losses, and infrastructure damage. As moderate to localized heavy rainfall is forecast over the next two weeks, particularly in southern areas, a heightened flood-risk is expected through mid-September.
Since mid-July, persistent and well above-average seasonal rains in Sudan caused significant levels of flooding. According to reports, over 45,000 people have been affected in West Kordofan, Kassala, El Gezira, Sennar, and Northern states. Meanwhile, large areas of western Ethiopia, southeastern South Sudan, and northern Uganda have experienced significant rainfall deficits for the past month, resulting in soil and crop moisture stress.

Elevation and derived datasets such as slope, aspect and drainage basins are important inputs into environmental and population models. These variables affect the distribution of human, plant and animal populations in the region.
Monthly vegetation index images are used to
characterize existing land cover. Other environmental information,
such as climate and elevation, is incorporated in the land cover analysis.
