The Tropical Rainfall Measuring Mission (TRMM) , managed by and the Japanese Space Agency flew over Nisha on January 28 and noticed that most of its rainfall is light to moderate, and spans from the south to the northeastern side of the storm. There were some isolated areas of heavy rainfall where was falling at about 2 inches per hour. However, most of the rain was moderate, falling at rates between 20 and 40 millimeters (.78 to 1.57 inches) per hour.
