Hurricane Teddy as it rapidly intensified (
ADT |
SATCON ) to a
Category 4 storm on 17 September 2020. The coldest cloud-top infrared brightness temperatures were in the -80 to -85ºC range.
Metep-A ASCAT surface scatterometer wind speeds were as high as 74 knots in the northwestern portion of the eyewall (below).
