Hurricane Earl is still a powerful category four hurricane on the Saffir-Simpson Scale as it approaches the North Carolina coast today. NASA’s Tropical Rainfall Measuring Mission (TRMM) satellite observed the high rates rain was falling within Earl, in some areas more than 2 inches per hour. Today, the Global Hawk unmanned aircraft is also flying into the eye of Hurricane Earl at altitudes of 60,000 feet to gather information about the storm. Hurricane Earl became the most powerful hurricane of the 2010 Atlantic season early on September 2 when its sustained winds reached 120 kts (~138 mph).

It was still intensifying when the TRMM satellite passed near its location on 2 September 2010 at 0602 UTC (2:02 a.m. EDT). The TRMM Microwave Imager (TMI) data were used in the rainfall analysis that showed heavy rainfall, particularly in the northwest quadrant of Earl’s very distinct circular eye. TRMM is managed by NASA and the Japanese Space Agency, and images are created at NASA’s Goddard Space Flight Center, Greenbelt, Md.
