AFTER AN EARLY MORNING BURST OF DEEP CONVECTION...THUNDERSTORM
ACTIVITY HAS BEEN ON THE WANE SINCE THE PREVIOUS ADVISORY AND
SATELLITE INTENSITY ESTIMATES INDICATE HECTOR IS BARELY HANGING ON
TO TROPICAL STORM STATUS. MODERATE EAST-SOUTHEASTERLY VERTICAL WIND
SHEAR IS EXPECTED TO KEEP HECTOR FROM STRENGTHENING OVER THE NEXT
24 HOURS OR SO. AFTER THAT...THE COMBINATION OF INCREASING SHEAR
AND COOLER SEA-SURFACE TEMPERATURES IS EXPECTED TO INDUCE STEADY
WEAKENING AND DISSIPATION BY 96-120 HOURS. THE OFFICIAL INTENSITY
FORECAST IS SIMILAR TO THE PREVIOUS ADVISORY AND FOLLOWS THE TREND
IN THE SHIPS AND LGEM INTENSITY MODELS.

THE INITIAL MOTION ESTIMATE IS 270/4. VISIBLE SATELLITE IMAGERY
INDICATES THAT HECTOR HAS BEEN DRIFTING TOWARD THE WEST OR EVEN A
LITTLE SOUTH OF WEST SINCE THE PREVIOUS ADVISORY. AS THE CONVECTION
WAXES AND WANES OVER THE NEXT DAY OR SO...A SLOW ERRATIC MOTION
TOWARD THE WEST-NORTHWEST OR WEST IS EXPECTED UNTIL THE SYSTEM
DECOUPLES COMPLETELY FROM ANY CONVECTION. AFTER THAT OCCURS...
HECTOR WILL BE A REMNANT LOW PRESSURE SYSTEM THAT WILL BE STEERED
WESTWARD BY THE LOW-LEVEL EASTERLY TRADE WIND FLOW. THE OFFICIAL
FORECAST IS SIMILAR TO THE PREVIOUS ADVISORY AND IS CLOSE TO THE
CONSENSUS MODELS TV15 AND TVCE.
