Hurricane Karina Special Discussion Number  14
NWS National Hurricane Center Miami FL       EP112026
500 PM PDT Sun Aug 30 2026

The satellite presentation of Karina has improved immensely over the 
past several hours. Very cold cloud top temperatures of -70 to -75 C 
now completely surround a warm eye, with temperatures near 0 to -5 
C. An earlier GPM GMI microwave pass also revealed a compact and 
well-established eye and pronounced curved banding around the 
center. Karina is moving over very warm sea surface temperatures 
near 29 C and remains in an environment highly conducive to further 
intensification. Objective intensity estimates have also increased 
rapidly over the past several hours, ranging from 88-109 kt. Based 
on the satellite presentation, microwave imagery, environmental 
conditions and objective intensity estimates, the initial intensity 
is set at 110 kt, making Karina a major hurricane. The intensity 
forecast has been increased from the previous advisory.

There were no changes made to the track or wind radii forecasts. A 
new forecast will be issued at 0300 UTC.
