1. REMARKS: THIS CANCELS REF A (WTIO PGTW 200030). THE AREA OF 
CONVECTION (INVEST 93B) PREVIOUSLY LOCATED NEAR 16.0N 96.6E IS NOW 
LOCATED NEAR 16.6N 97.4E, APPROXIMATELY 72 NM EAST OF YANGON, 
MYANMAR. ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY DEPICTS 
CONVECTIVE BANDS WRAPPING INTO A LOW LEVEL CIRCULATION CENTER (LLCC) 
WITH PERSISTENT CONVECTION IN THE SOUTHERN AND WESTERN PERIPHERIES. 
SATELLITE IMAGERY AND THAI RADAR INDICATE THAT THE LLCC CROSSED OVER 
LAND NEAR MAWLAMYINE, MYANMAR, OFFSETTING THE SUPPORT GIVEN BY THE 
SURROUNDING WARM (30-31C) SEA SURFACE TEMPERATURES (SST), LOW (<15 
KT) VERTICAL WIND SHEAR (VWS), AND CONSIDERABLE EQUATORWARD OUTFLOW. 
GLOBAL MODELS ARE IN AGREEMENT THAT INVEST 93B WILL DISSIPATE AS IT 
TRACKS OVER LAND. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 
28 TO 33 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 
999 MB. GIVEN THAT INVEST 93B IS FORECAST TO REMAIN INLAND, IT IS NO 
LONGER SUSPECT FOR THE DEVELOPMENT OF A TROPICAL CYCLONE WITHIN THE 
NEXT 24 HOURS.//
