Hurricane Darby Special Discussion Number   8

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.
