Climate Prediction Center’s Africa Hazards Outlook For USAID / FEWS-NET- August 2 – August 8, 2012
1) Above-average rains observed in western Sudan and eastern Chad during the past thirty days have caused localized flash floods. With additional heavy rain forecast for the next week, localized flash flooding could occur.
2) Torrential coastal rain showers across far western parts of West Africa has resulted in weekly rainfall greater than 300mm during the past week and substantial thirty-day rainfall surpluses greater than 200mm. The copious amounts of rain has caused in flash flooding in Sierra Leone and Guinea. With heavy rain forecast in Guinea and Guinea-Bissau, there is an increased chance for flooding during the next week.
3) A consistent northerly position of the Intertropical Front during the past two months has caused above-average rain to fall in the northern Sahel, providing beneficial conditions for the development/breeding of desert locusts. Conditions are expected to remain favorable during the next week. Currently, efforts are underway in Niger to mitigate the impact.
