(1) THE AREA OF CONVECTION (INVEST 98W) PREVIOUSLY LOCATED
NEAR 23.6N 126.9E, IS NOW LOCATED NEAR 24.2N 126.7E, APPROXIMATELY
145 NM SOUTH OF KADENA AB, OKINAWA. ANIMATED ENHANCED INFRARED
IMAGERY SHOWS A NOW PARTIALLY EXPOSED LOW LEVEL CIRCULATION WITH THE
CONVECTION BEING SHEARED AWAY TO THE SOUTHWEST. A 070302Z METOP-A
ASCAT PASS REVEALS THE LOW LEVEL CIRCULATION TRANSITIONING TO A WAVE-
LIKE FEATURE WITH A SMALL SWATH OF 20 KNOT WINDS TO THE NORTHEAST OF
THE CIRCULATION. A 062222Z F-17 37 GHZ SSMIS MICROWAVE IMAGE DEPICTS
A REDUCTION IN BANDING AND FURTHER ELONGATION OF THE LOW LEVEL
CIRCULATION. THE SYSTEM IS IN AN AREA OF DISORGANIZED OUTFLOW WITH
VERTICAL WIND SHEAR (VWS) VALUES OF 15 TO 20 KNOTS. SEA SURFACE
TEMPERATURES (SST) REMAIN VERY WARM AT 28 TO 30 CELSIUS. ALL MODELS
ARE IN GOOD AGREEMENT THAT THE SYSTEM WILL TRACK NORTHWEST WHILE
CONTINUING TO WEAKEN. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE
NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS DOWNGRADED TO LOW. SEE
REF A (WTPN21 PGTW 070230) FOR FURTHER DETAILS.
