Rainy Days:
Eastern Sates:
The first dekad of August brought above average rainfall in Kassala and Halfa El Gadida and
below average rainfall in Gedaref. Rainfall performance in Kassala and Halfa El Gadida is
getting better that that of Gedaref during early August. Kassala recorded 50 mm and Halfa El

Halfa El Gadida since late July above average rainfall. (See Fig 1)
Figure 1: Dekdal Rainfall amounts 2014 compared with LTA 1981-2010 for Kassala, Halfa El Gadida &
Gedaref stations.
In term of cumulative rainfall, Halfa El Gadida and Gedaref stations showed above average
cumulative rainfall amounts. In contrast Kassala station still continued to show below average
cumulative rainfall amounts since the start of the rainy season until this dekad. (See Fig 2)
Generally, considerable improvements in rainfall performance in the eastern part are
noticeable since late July, which will result in good growing season and pastoral development.

Central States:
1. Sennar:
Rainfall performance in Sennar state during this period is from average to below average.
Abu Naama received near average rainfall (62mm), Um Banien received below average rainfall
(46 mm) and Sennar received far below average rainfall (6mm). The overall performance of the

Banien stations.

In term of cumulative rainfall, Sennar Abu Naama and Um Banien stations showed above
average cumulative rainfall, this is due to the early July high rainfall amounts that received in
Um Banien station and late July good rainfall that registered in Sennar and Abu Naama
stations.(See Fig 5).
Figure 5: Cumulative Rainfall 2014 Vs Cumulative Average for Sennar, Abu Naama & Um Banien

cumulative rainfall the station showed on average cumulative rainfall in this dekad. The
cumulative rainfall decrease as the decrease of rainfall amounts that registered in the station

equal to the last dekad rainfall number. (See Fig 10)

The cumulative rainfall was above average in Geniena and Fasher during this dekad and below
average in Nyala station. The situation in Fasher is reformed by these late above average rains.
The cumulative rainfall exceeded its average amounts as a result of the early August good
