1. REMARKS: THIS CANCELS REF A (WTPN21 PGTW 022130). THE AREA OF
CONVECTION (INVEST 94W) HAS PREVIOUSLY LOCATED NEAR 17.4N 113.9E, IS
NOW LOCATED NEAR 18.5N 108.5E, APPROXIMATELY 134 NM NORTH-NORTHEAST
OF HUE, VIETNAM. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY AND A
031411Z 89GHZ METOP-B MICROWAVE IMAGE DEPICT A WEAK LOW LEVEL
CIRCULATION (LLC) WITH SOME FLARING CONVECTION. UPPER LEVEL ANALYSIS
SHOWS A FAVORABLE ENVIRONMENT WITH LOW (10-15KT) VERTICAL WIND SHEAR
AND MODERATE DIVERGENCE. SEA SURFACE TEMPERATURES ARE FAVORABLE AT
28-29C. GLOBAL MODELS ARE HAVING TROUBLE RESOLVING THE SYSTEM DUE TO
INTERACTION WITH TD 16W TO THE WEST-SOUTHWEST. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 998 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS NO LONGER EXISTS.//
