Typhoon Prapiroon's South-Sided Rainfall (IMAGE) NASA/Goddard Space Flight Center Caption The TRMM satellite flew above Typhoon Prapiroon on Oct. 15, 2012 at 0632 UTC (2:32 a.m. EDT). Prapiroon's sustained wind speeds had dropped to 70 knots (~81 mph) with a large and ragged eye (black) being its dominant feature. TRMM's Microwave Imager (TMI) data indicated that the most intense rain bands south of Prapiroon's eye were dropping rain at a rate of about 30-40 mm/hour (~1.2 to 1.6 inches).
