Tropical Storm Maria was born in the western North Pacific Ocean and has a large area of moderate rainfall, as NASA's TRMM satellite revealed today, Oct. 15. NASA's TRMM satellite noticed that most of Maria's rainfall was occurring northeast of the storm's center. Maria is the twenty-third tropical cyclone of the western North Pacific season.
When NASA's Tropical Rainfall Measuring Mission (TRMM) satellite passed over Tropical Storm Maria on Oct. 15 at 1329 UTC (9:29 a.m. EDT) light to moderate rainfall was occurring northeast of the center and falling at a rate between .78 to 1.57 inches/20 to 40 mm per hour. There was also a small area of heavy rain falling at 2 inches/50 mm per hour.
