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 91A) PREVIOUSLY LOCATED NEAR 
24.3N 70.5E IS NOW LOCATED NEAR 23.9N 69.1E, APPROXIMATELY 126 NM EAST-
SOUTHEAST OF KARACHI. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICT 
FORMATIVE BANDING WITH EMBEDDED CONVECTION OVER THE NORTHWESTERN COAST 
OF INDIA. ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE CONDITIONS FOR 
DEVELOPMENT, INCLUDING HIGH (20-25KTS) VERTICAL WIND SHEAR, STRONG 
UPPER-LEVEL OUTFLOW EQUATORWARD, WARM (28-29C) SEA SURFACE TEMPERATURE, 
AND MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 992 MB. GLOBAL 
DETERMINISTIC MODELS INDICATE THAT 91A WILL CONTINUE TO DEVELOP WITH A 
WESTWARD TRACK OVER THE NEXT 24 HOURS. MAXIMUM SUSTAINED SURFACE WINDS 
ARE ESTIMATED AT 28 TO 33 KNOTS. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 28 TO 33 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO 
BE NEAR 998 MB. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 28 TO 
33 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 994 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.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA. 1.B. (1) TO 
HIGH.////
