Coldest cloud top temperatures (yellow) of strongest thunderstorms were in the eyewall, the area of thunderstorms surrounding the open eye. Those storms had cloud tops as cold as or colder than minus 80F/minus 62.2C. They were surrounded by powerful storms (red) with cloud tops as cold as minus 70F/minus 56.6C.
