In the infrared image of Hurricane Beryl, close to the time of landfall near Houston, Texas, in the early morning of July 8, 2024, the large purple areas indicate very cold clouds carried high into the atmosphere by deep thunderstorms and associated with heavy rainfall. Warmer areas with shallower rain clouds are shown in blue and green. The orange and red areas represent mostly cloud-free air.
