At this time the storm was a category 1 hurricane with sustained winds of 56 knots (64 mph), a pressure reading of 994 millibars. The cloud cover in this animation is taken by TRMM's Visible and Infrared Scanner(VIRS) and the GOES spacecraft. The rain structure is taken by TRMM's Tropical Microwave Imager (TMI) and TRMM's Precitation Radar(PR) instruments. TRMM looks underneath of the storm's clouds to reveal the underlying rain structure. The colored isosurface under the clouds show the rain seen by the PR instrument.    Hurricane Bill forms in the Atlantic. TRMM's Microwave Imager and Precipitation Radar instruments revealed that Hurricane Bill has bands of heavy rainfall.
