TRMM images show seasonal rains flooding Africa's Sahel 
The unusually heavy rains caused flooding in as many as 17 countries and affected more than a million people across Africa, reported BBC News on September 17. This image illustrates how extensive the extreme rainfall was. The image was made with data collected by the Tropical Rainfall Measuring Mission (TRMM) satellite between August 20 and September 21, 2007. The average daily totals recorded during this period are compared with average rainfall totals recorded during the same period since TRMM’s launch in 1997. Regions that received more rain per day than average are blue and green, while places that received less rain are yellow to red.
