Tropical Depression Hermine

Tropical cyclones are usually big rainmakers once they make landfall and they start to fizzle out, and Hermine, now a tropical depression over Texas is no exception. Rainfall data on Hermine's heavy rains were gathered by NASA and the Japanese Space Agency's Tropical Rainfall Measuring Mission (TRMM) satellite. That data was used to create a map of potential flood areas that showed areas of flooding and potential flooding over a large area in southeastern and central Texas.

Hal Pierce of NASA's TRMM team at the NASA Goddard Space Flight Center in Greenbelt, Md. used the rainfall data from TRMM's rainfall measurements and various reporting stations to create a flood potential map. The map is color-coded and depicts areas with severe flood potential on Sept, 8.
