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) THE AREA OF CONVECTION (INVEST 90S) PREVIOUSLY LOCATED NEAR 
4.0S 74.5E IS NOW LOCATED NEAR 5.2S 73.9E, APPROXIMATELY 159 NM NORTH-
NORTHEAST OF DIEGO GARCIA. ENHANCED INFRARED SAETLLITE IMAGERY AND A 
150101Z SSMIS 91GHZ MICROWAVE IMAGE DEPICT A VERY BROAD AREA OF DENSE, 
PERSISTENT CONVECTION IN THE NORTHWESTERN PERIPHERY OF THE INVEST AREA. 
A CONSOLIDATE LOW LEVEL CIRCULATION (LLC) IS BEGINNING TO FORM WITH 
FRAGMENTED BANDING BEGINNING TO ORGANIZE. ENVIRONMENTAL ANALYSIS REVEALS 
THAT INVEST 90S IS IN A MARIGNALLY FAVORABLE ENVIRONMENTAL FOR 
DEVELOPMENT WITH WARM (28-30C) SEA SURFACE TEMPERATURES AND STRONG 
POLEWARD OUTFLOW OFFSET BY HIGH (25-30KT) VERTICAL WIND SHEAR. MODEL 
GUIDANCE IS IN GOOD AGREEMENT THAT INVEST 90S WILL CONTINUE TO GRADUALLY 
INTENSIFY AND TRACK WEST-SOUTHWESTWARD OVER THE NEXT 24-48 HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 28 TO 33 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.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(1) TO MEDIUM.//
