The latest infrared image from NASA's Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite illustrates the growing flood threat from now Tropical Storm Harvey. In the false-color image, acquired at 2:29 p.m. CDT (19:29 UTC) on Aug. 28, 2017, a large area of dark blue and purple centered along the southeastern Texas coast denotes the coldest cloud top temperatures and strongest thunderstorms. A second area of intense precipitation is visible over southeastern Louisiana. Harvey has reemerged over the Gulf of Mexico, but the National Hurricane Center forecasts only a small amount of strengthening before the storm moves slowly north and inland again.
