28DEC24. TROPICAL CYCLONE 05S (FIVE), LOCATED APPROXIMATELY 142
NM SOUTH-SOUTHWEST OF THE COCOS ISLANDS, HAS TRACKED SOUTH-
SOUTHWESTWARD AT 08 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A ONCE-AGAIN FULLY EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC), DISPLACED TO THE NORTHEAST OF RAPIDLY WEAKENING CONVECTION. THE ANIMATED MSI INDICATES THAT THE SYSTEM HAS MULTIPLE VORTICES ROTATING AROUND A RAGGED BUT DEFINED CENTER AND THE INITIAL POSITION WAS PLACED IN THE CENTROID OF THE MULTI-VORTEX CIRCULATION WITH HIGH CONFIDENCE. THE INITIAL INTENSITY IS ASSESSED AT 30 KNOTS WITH HIGH CONFIDENCE, BASED PRIMARILY ON A 280307Z ASCAT-B BULLSEYE PASS WHICH REVEALED A MUCH WEAKER WIND FIELD THAN PREVIOUSLY ASSESSED. MAXIMUM WINDS WERE UNDER THE CONVECTION TO THE SOUTH OF THE LLCC, BUT REGARDLESS, WERE SHOWN TO BE JUST 30-34 KNOTS. THE REMAINDER OF THE WIND FIELD IS PREDOIMINANTLY LESS THAN 30 KNOTS. THE ENVIRONMENT IS UNFAVORABLE, WITH MODERATE (20-25 KNOTS) NORTHEASTERLY SHEAR, DRY MID-LEVEL AIR WRAPPING UP ACROSS THE NORTHERN REACHES OF THE CIRCULATION AND RELATIVELY COOL (25-26C) SSTS BEING THE PRIMARY NEGATIVE INFLUENCES. POLEWRAD OUTFLOW IS STRONG HOWEVER, FLOWING SOUTHWARD INTO A BROAD TROUGH PASSING TO THE SOUTH. TC 05S WILL CONTINUE TO SLOWLY DRIFT SOUTHWARD IN A GENERALLY WEAK STEERING PATTERN, CONTINUE TO FACE MODERATE TO STRONG NORTHEASTERLY WIND SHEAR, BECOME INCREASINGLY SMOTHERED BY DRY MID-LEVEL AIR AND MOVE INTO COOLER WATERS, RESULTING IN A CONTINUED WEAKENING TREND THROUGH THE NEXT 12 HOURS. THE REMNANT LOW-LEVEL VORTEX IS LIKELY TO PERSIST FOR SOME TIME, TURNING TO A WEST-SOUTHWESTWARD TRACK AND MAINTAINING WINDS IN THE 25-30 KNOT RANGE. THUS, IT WILL BEAR CLOSE WATCHING FOR ANY SIGNS OF REGENERATION.
THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON
WRNCEN PEARL HARBOR HI. THE SYSTEM WILL BE CLOSELY MONITORED FOR
SIGNS OF REGENERATION. MINIMUM CENTRAL PRESSURE AT 280600Z IS
1003 MB. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 280600Z IS 12 FEET.
