On Sept. 1 at 11:35 p.m. EDT (Sept. 2 at 335 UTC), the MODIS instrument aboard NASA's Terra satellite gathered temperature information about Tropical Storm Nana's cloud tops. MODIS found the most powerful thunderstorms (yellow) were around the center of the storm, where temperatures were as cold as or colder than minus 80 degrees (minus 62.2 degrees Fahrenheit). That area was surrounded by slightly less powerful storms (red) where cloud top temperatures were as cold as or colder than minus 70 degrees Fahrenheit (minus 56.6 Celsius).
