RMKS/
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) AN AREA OF CONVECTION (INVEST 91S) HAS PERSISTED NEAR 12.0S 
98.9E, APPROXIMATELY 121 NM EAST OF COCOS ISLANDS. ANIMATED ENHANCED 
INFRARED SATELLITE IMAGERY DEPICTS A BROAD AREA OF TURNING WITH FLARING, 
DEEP CONVECTION. A 172043 SSMIS SHOWS A LOOSELY DEFINED AND POORLY 
ORGANIZED LLCC.  UPPER-LEVEL ANALYSIS INDICATES 91S IS IN A FAVORABLE 
ENVIRONMENT FOR DEVELOPMENT WITH LOW (<15 KNOT) VWS, GOOD DIVERGENCE 
ALOFT, AND WARM (28-30C) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN 
GOOD AGREEMENT THAT 91S WILL CONTINUE TO TRACK GENERALLY SOUTHWARD AND, 
THOUGH OVERALL CONDITIONS ARE FAVORABLE, THE LACK OF A DISTINCT, 
CONSOLIDATED LLCC AT THIS TIME WILL SERVE TO LIMIT THE POTENTIAL 
DEVELOPMENT. 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 LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: ADDED LOW AREA IN PARA. 2.B.(1).//
