Hurricane Norman Special Discussion Number   9
NWS National Hurricane Center Miami FL       EP162018
530 AM PDT Thu Aug 30 2018

Satellite data show that Norman continues to rapidly strengthen.
Objective Dvorak data T-numbers from UW/CIMSS have increased to T6.5
or higher and the latest TAFB subjective data T-number is T6.5.
These estimates support an initial intensity of 125 kt, making
Norman a category 4 hurricane on the Saffir-Simpson Hurricane Wind
Scale.  As a result of the increased initial intensity, the NHC
intensity forecast has been adjusted upward through 36 h, but it is
otherwise unchanged.  There has been no change to the NHC track
forecast.
