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 14.3N 97.8E, APPROXIMATELY 176 NM SOUTH-
SOUTHEAST OF YANGON, MYANMAR. ANIMATED ENHANCED INFRARED (EIR) SATELLITE 
IMAGERY DEPICTS AN OBSCURED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH 
GOOD MID-LEVEL ROTATION PRESENT JUST OFFSHORE MYANMAR. ENVIRONMENTAL 
ANALYSIS INDICATES A MARGINAL ENVIRONMENT FOR DEVELOPMENT WITH LOW TO 
MODERATE (15-20 KTS) VERTICAL WIND SHEAR, GOOD EQUATORWARD AND WESTWARD 
OUTFLOW ALOFT, AND WARM (28-29 C) SEA SURFACE TEMPERATURES, OFFSET BY 
THE LIMITED TIME OVER WATER. GLOBAL DETERMINISTIC AND ENSEMBLE MODELS 
INDICATE STEADY DEVELOPMENT OVER THE UPCOMING 24 HOURS AS THE SYSTEM 
TRANSITS NORTHWESTWARD OFF THE COAST OF MYANMAR OVER COASTAL WATER. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28 KNOTS. MINIMUM 
SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR 
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 
HOURS IS UPGRADED TO MEDIUM.
      (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 MEDIUM.//
