NASA's Infrared Look at Tropical Cyclone Khanun

Caption

NASA's Aqua satellite captured a look at Khanun's cloud top temperatures on July 15, 2012, at 1635 UTC (12:35 p.m. EDT) when it was a tropical depression. Coldest cloud top temperatures (purple) were as cold as or colder than -63 Fahrenheit (-52 Celsius), indicating strong thunderstorms. That was a clue to forecasters that Khanun would become a tropical storm, which it did the next day.
