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.

Danielle formed as a tropical depression over the Atlantic Ocean on August 22, 2010, and strengthened to a tropical storm the next day. On August 27, Danielle strengthened into a major hurricane. By August 29, the hurricane was back to category one and losing energy in the North Atlantic.
