1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED NEAR 
14.7N 98.6E IS NOW LOCATED NEAR 14.4N 98.0E, APPROXIMATELY 177NM NM 
SOUTHEAST OF YANGON, MYANMAR. ANIMATED ENHANCED INFRARED (EIR) SATELLITE 
IMAGERY DEPICTS A CONSOLIDATING LOW-LEVEL CIRCULATION CENTER (LLCC) WITH 
IMPROVED CONVECTIVE BANDING. A 271429Z ASCAT-B PASS REVEALS A DEFINED 
CIRCULATION WITH 30KT WINDS OFF THE COAST OF MYANMAR. A 271449Z GMI 
COLOR 37GHZ MICROWAVE IMAGE DEPICTS CONVECTIVE BANDING WRAPPING TIGHTLY 
INTO A WELL-DEFINED CIRCULATION CENTER. ENVIRONMENTAL ANALYSIS INDICATES 
A FAVORABLE AREA FOR DEVELOPMENT WITH LOW VERTICAL WIND SHEAR (10-
15KTS), GOOD EQUATORWARD AND POLEWARD OUTFLOW, AND WARM SEA SURFACE 
TEMPERATURES (28-29C). GLOBAL DETERMINISTIC AND ENSEMBLE MODELS INDICATE 
A SHORT 24-HOUR WINDOW FOR DEVELOPMENT AS THE SYSTEM TRACKS NORTH-
NORTHWESTWARD ALONG THE COAST OF MYANMAR. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 23 TO 28 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1001 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO 
HIGH. SEE REF A (WTIO21 PGTW 271730) FOR FURTHER DETAILS.
      (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.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 1.B.(1) TO HIGH.//
