Hurricane Darby Special Discussion Number 8
NWS National Hurricane Center Miami FL EP052022
1200 AM HST Mon Jul 11 2022
This is a special advisory to update the intensity of the hurricane
and the shorter-term intensity forecast. Recent enhanced infrared
satellite images indicate that Darby's eye has become significantly
better defined and embedded within cloud tops colder than -70C.
Objective Dvorak T-numbers now support an intensity of 90 kt. Based
on this rapid strengthening, the official intensity forecast has
been adjusted upward through the 24-hour period, and now shows Darby
becoming a major hurricane. This is above the model guidance but
follows the current intensification trend.
No changes have been made to the NHC intensity forecast after 24
hours, or to the official track forecast.
