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:
      (1) AT 09SEP25 0600Z, TROPICAL CYCLONE 03S (THREE) WAS LOCATED 
NEAR 9.1S 69.3E, APPROXIMATELY 225 NM WEST-SOUTHWEST OF DIEGO GARCIA, 
AND HAD TRACKED WESTWARD AT 05 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO 45 KNOTS. 
SEE REF A (WTXS31 PGTW 090900) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 93S) HAS PERSISTED NEAR 5.2S 
95.0E, APPROXIMATELY 435 NM NORTH-NORTHWEST OF THE COCOS ISLANDS. 
ANIMATED ENHANCED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A BROAD AREA 
OF CYCLONIC TURNING WITH WESTERLY WINDS WRAPPING INTO THE CIRCULATION. 
FURTHERMORE, A 090706 89 GHZ MICROWAVE IMAGE REVEALS LOW-LEVEL BANDING 
AND POCKETS OF DEEP CONVECTION ALONG THE NORTHERN PERIPHERY. 
ENVIRONMENTAL ANALYSIS INDICATES MARGINALLY UNFAVORABLE CONDITIONS WITH 
MODERATE POLEWARD OUTFLOW ALOFT, AND WARM (28-29 C) SEA SURFACE 
TEMPERATURES, OFFSET BY MODERATE TO HIGH (20-25 KTS) NORTHERLY VERTICAL 
WIND SHEAR. ENSEMBLE MODELS ARE IN GOOD AGREEMENT THAT 93S WILL TRACK 
SOUTH-SOUTHWEST WITH GRADUAL INTENSIFICATION WHILE DETERMINISTIC MODELS 
ALSO SHOW DEVELOPMENT, BUT REMAIN BELOW TC CRITERIA OVER THE NEXT 48 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. 
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 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).//
