Soon after it formed in late August 2010, Tropical Storm Danielle brought isolated areas of heavy rain inside wider expanses of lighter rainfall. This image shows Danielle’s rainfall amounts, as observed by the Tropical Rainfall Measuring Mission (TRMM), on August 22, 2010. Color-coded precipitation amounts (red is the highest and blue is the lowest) are superimposed on a photo-like image. Small pockets of especially intense rainfall—50 millimeters, or almost 2 inches per hour—are clustered near the center of the storm, and are surrounded by a wider area of lighter rain.
