The VIIRS instrument on NASA-NOAA’s Suomi NPP satellite captured a thermal image of Hurricane Maria on Sept. 20 at 2:12 a.m. EDT. The image showed very cold cloud top temperatures in the powerful thunderstorms in Maria’s eyewall. Maria’s eye was just east of the American Virgin Islands, and its northwestern quadrant stretched over Puerto Rico. via NASA http://ift.tt/2xn5mNK
