HURRICANE EUGENE DISCUSSION NUMBER  16
NWS NATIONAL HURRICANE CENTER MIAMI FL       EP052011
800 PM PDT WED AUG 03 2011
 
EUGENE LIKELY REACHED ITS PEAK INTENSITY ABOUT SIX HOURS AGO WHEN
CLOUD TOPS TEMPERATURES OF AROUND -75C SURROUNDED THE EYE. SINCE
THAT TIME DEEP CONVECTION HAS BEEN GRADUALLY WEAKENING...ALTHOUGH
THE EYE REMAINS WELL-DEFINED WITH MESOVORTICIES EVIDENT IN THE LAST
FEW VISIBLE IMAGES. A BLEND OF THE LATEST SATELLITE INTENSITY
ESTIMATES YIELDS AN INITIAL WIND SPEED OF ABOUT 110 KT. THE
HURRICANE IS CURRENTLY OVER 27C WATERS...AND IS FORECAST TO MOVE
OVER SEA SURFACE TEMPERATURES LOWER THAN 26C BY TOMORROW MORNING.
THESE COOL WATERS COMBINED WITH AN INCREASINGLY STABLE ATMOSPHERE
SHOULD CAUSE STEADY OR RAPID WEAKENING...AND EUGENE IS NOW FORECAST
TO BECOME A REMNANT LOW IN ABOUT FOUR DAYS AS IT REACHES 22C WATERS.
THE OFFICIAL INTENSITY FORECAST IS VERY NEAR THE INTENSITY MODEL
CONSENSUS.

THE HURRICANE REMAINS ON TRACK...MOVING WEST-NORTHWESTWARD AT 11 KT
TO THE SOUTH OF A MID-LEVEL RIDGE CENTERED OVER THE SOUTH-CENTRAL
UNITED STATES.  THIS MOTION IS EXPECTED TO CONTINUE DURING THE NEXT
COUPLE OF DAYS...FOLLOWED BY A DECREASE IN FORWARD SPEED ONCE THE
CYCLONE BECOMES A SHALLOWER SYSTEM.  THE NEW NHC TRACK FORECAST IS
VERY CLOSE TO THE PREVIOUS ONE AND AGAIN DISREGARDS THE SLOWER GFDL
AND HWRF MODELS AT THE END OF THE FORECAST PERIOD.
