IMERG Data from Wilfred (IMAGE) NASA/Goddard Space Flight Center Caption On Sept. 18 at 5:30 a.m. EDT (0930 UTC), NASA's IMERG estimated Tropical Storm Wilfred was generating as much as 30 mm/1.18 inches of rain (dark pink) around the center of circulation. Rainfall throughout most of the storm and in fragmented bands of thunderstorms to the southeast of the center, was occurring between 5 and 15 mm (0.2 to 0.6 inches/yellow and green colors) per hour. The rainfall data was overlaid on infrared imagery from NOAA's GOES-16 satellite.
