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 117 NM 
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 1003 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN 
THE NEXT 24 HOURS IS UPGRADED TO HIGH.
      (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.//
