1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   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:
      (1) THE AREA OF CONVECTION (INVEST 92S) PREVIOUSLY LOCATED NEAR 
5.4S 84.2E IS NOW LOCATED NEAR 6.5S 81.5E, APPROXIMATELY 542 NM EAST-
NORTHEAST OF DIEGO GARCIA. ANIMATED ENHANCED INFRARED (EIR) SATELLITE 
IMAGERY DEPICTS WELL ORGANIZED DEEP CONVECTIVE STRUCTURE OVER A 
TIGHTENING LOW LEVEL CIRCULATION CENTER (LLCC). A PARTIAL 131345Z SSMIS 
F-17 91GHZ MICROWAVE IMAGE REVEALS FRAGMENTED DEEP CONVECTIVE BANDING 
WRAPPING INTO THE LLCC FROM THE NORTH AND WEST. A 131531Z ASCAT-A PASS 
SHOWS A SLIGHTLY ELONGATED LLCC WITH A LARGELY ASYMMETRIC WIND FIELD 
CONTAINING 25 TO 30 KNOT WINDS TO THE NORTH AND SOUTH. INVEST 92S IS 
CURRENTLY IN A FAVORABLE ENVIRONMENT WITH EXCELLENT RADIAL OUTFLOW, LOW 
(10 TO 15 KNOTS) VERTICAL WIND SHEAR, AND WARM (29 CELSIUS) SEA SURFACE 
TEMPERATURES. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT INVEST 92S WILL 
TRACK SOUTHWESTWARD INTENSIFYING TO WARNING IN 12 TO 24 HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 30 TO 35 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS 
REMAINS HIGH.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
