Tropical Depression Five (TD5) may not be a tropical depression anymore, but NASA’s TRMM satellite has noticed that its remnant low pressure circulation is making for a very bad and wet Friday the 13th for residents from southeastern Louisiana east to the Florida panhandle. Even when a tropical system gets downgraded into a low pressure area, there is still the possibility of inland flooding from heavy rainfall, and that’s what this low is creating.

The Tropical Rainfall Measuring Mission (TRMM) has been called a “rain gauge in space” and can provide accurate measurements of rainfall in tropical and sub-tropical areas around the world. TRMM data, along with information from other satellites, allows researchers to see how much rain is falling over most of the world every three hours and map areas of potential flooding. Maps that show areas of potential floods use precipitation radar data and high resolution measurements of water content of clouds made by microwave radiometers.
