1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 02OCT25 1200Z, TROPICAL CYCLONE 01B (ONE) WAS LOCATED 
NEAR 19.5N 84.7E, APPROXIMATELY 278 NM SOUTHWEST OF KOLKATA, INDIA, 
AND HAD TRACKED NORTHWARD AT 09 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO 45 
KNOTS. SEE REF A (WTIO31 PGTW 021500) FOR THE FINAL WARNING ON THIS 
SYSTEM. 
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 90A) PREVIOUSLY LOCATED NEAR 
20.7N 68.2E IS NOW LOCATED NEAR 21.7N 67.9E, APPROXIMATELY 310 NM 
WEST-NORTHWEST OF MUMBAI, INDIA. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY AS WELL AS A 10021200Z GMI 89GHZ MICROWAVE PASS DEPICT A 
PARTIALLY EXPOSED LOW LEVEL CIRCULATION CENTER SLOWLY CONSOLIDATING 
AND BECOMING EMBEDDED WITHIN FLARING CONVECTION OVER THE CENTER AND 
FORMATIVE BANDING ALONG WESTERN PERIPHERY OF THE CIRCULATION. 
ENVIRONMENTAL ANALYSIS INDICATES FAVORABLE CONDITIONS FOR DEVELOPMENT 
WITH LOW VWS (10-15 KNOTS), GOOD EQUATORWARD OUTFLOW ALOFT, AND WARM 
SEA SURFACE TEMPERATURES (28-30 C).  GLOBAL DETERMINISTIC MODELS ARE 
IN GOOD GENERAL AGREEMENT ON DEVELOPMENT OVER THE NEXT 24 HOURS WITH 
MOST MODELS KEEPING THE SYSTEM AT OR SLIGHTLY ABOVE WARNING CRITERIA.  
THE SYSTEM IS EXPECTED TO HAVE A SLUGGISH WESTWARD TRACK OVER THE NEXT 
48 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 28 TO 33 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 995 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.
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: UPDATED PARA 1.A.(1) WITH 01B FINAL 
WARNING INFORMATION.//
