Andrea

Tropical Storm Andrea formed on the late afternoon of June 5th, 2013 from a trough of low pressure that had persisted for several days over the southeast Gulf of Mexico. This trough extended out over the Gulf from the Yucatan Peninsula and provided the focus for the development of showers and thunderstorms in the region, eventually leading to the formation of Tropical Storm Andrea. With its suite of passive microwave and active radar sensors, TRMM is ideally suited to measure rainfall from space. For increased coverage, TRMM is used to calibrate rainfall estimates from other additional

The TRMM satellite satellite flew directly above tropical storm Andrea on Wednesday June 5, 2013 at 2234 UTC (6:34 PM EDT) and received data used in the image on the left. These data were captured just over an hour after the National Hurricane Center (NHC) named tropical storm Andrea. A rainfall analysis from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments shows that moderate to heavy rain was wrapping around the eastern side of the storm. The heaviest rainfall of 124.5 mm/hr (~4.9 inches) from TRMM PR data was found on Andrea's southeast side. TRMM had another fairly
