1. REMARKS: THIS CANCELS REF A (WTPN22 PGTW 180200). THE AREA OF CONVECTION 
(INVEST 98W) PREVIOUSLY LOCATED NEAR 16.0N 114.6E IS NOW LOCATED NEAR 16.0N 
107.2E, APPROXIMATELY 58 NM WEST OF DA NANG, VIETNAM. ANIMATED 
MULTISPECTRAL SATELLITE IMAGERY DEPICTS AN OBSCURED LOW LEVEL CIRCULATION 
WITH FLARING CONVECTION TRACKING WESTWARD INLAND OVER VIETNAM. UPPER-LEVEL 
ANALYSIS INDICATES THE AREA HAS DRIFTED INTO AN AREA OF MODERATE VERTICAL 
WIND SHEAR (VWS) OF 10-15 KNOTS. GLOBAL MODELS INDICATE PERSISTENT MODERATE 
VWS ALONG THE TRACK OVER LAND WHERE IT WILL DISSIPATE DUE TO TOPOGRAPHIC 
INTERACTION. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 992 MB. INVEST 
98W HAS DISSIPATED OVER LAND AND IS NO LONGER SUSPECT FOR THE DEVELOPMENT 
OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.//
