TRMM Satellite Measures Rainfall in Tropical Storm Don (image) NASA/Goddard Space Flight Center Share Print E-Mail Caption The TRMM satellite had a fairly good view of tropical Storm Don when it passed over on July 28, 2011 at 0609 UTC (1:09 a.m. CDT). A red tropical storm symbol shows the position, north of Mexico's Yucatan peninsula, where Don was located at that time. A TRMM rainfall analysis showed Don was dropping moderate to heavy rainfall (red) of up to 2 inches/50 mm per hour in the eastern side of the small storm. The yellow and green areas indicate moderate rainfall between .78 to 1.57 inches (20 to 40 mm) per hour.
