/OCEAN/191800Z-201800ZMAY2022//RMKS/
1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 93B) HAS PERSISTED NEAR 
15.2N 96.4E, APPROXIMATELY 125 NM SOUTH-SOUTHWEST OF YANGON, 
MYANMAR. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY SHOWS A 
CONSOLIDATING BROAD MID LEVEL CIRCULATION WITH AN ASSOCIATED LOW 
LEVEL CIRCULATION (LLCC) COVERED BY DEEP CONVECTION ON THE WESTERN 
AND SOUTHERN SECTORS. DESPITE THE LAND INTERACTION ON THE LOWER 
LEVELS, ENVIRONMENTAL ANALYSIS INDICATES THE INVEST IS IN A 
GENERALLY FAVORABLE AREA OF DEVELOPMENT DEFINED BY LOW (5-10KTS) 
VERTICAL WIND SHEAR, WARM (29-30C) SEA SURFACE TEMPERATURES, AND 
FAIR EQUATORWARD OUTFLOW. GLOBAL DETERMINISTIC MODELS ARE IN 
AGREEMENT THAT INVEST 93B WILL CONTINUE DRIFTING EASTWARD INTO THE 
GULF OF MARTABAN OVER THE NEXT 48-72 HOURS WHERE IT WILL GRADUALLY 
INTENSIFY BEFORE MAKING LANDFALL IN MYANMAR. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 23 TO 28 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 UPGRADED TO LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH INDIAN OCEAN AREA (135E WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
