1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 22NOV20 0000Z, TROPICAL CYCLONE 03A (THREE) WAS LOCATED 
NEAR 10.5N 53.8E, APPROXIMATELY 535 NM EAST-SOUTHEAST OF ADEN, 
YEMEN, AND HAD TRACKED WESTWARD AT 18 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 50 KNOTS GUSTING 
TO 65 KNOTS. SEE REF A (WTIO31 PGTW 220300 AMD) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 96A) PREVIOUSLY LOCATED 
NEAR 7.1N 58.0E HAS DISSIPATED AND IS NO LONGER THE SUBJECT FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
      (2) THE AREA OF CONVECTION (INVEST 97B) PREVIOUSLY LOCATED 
NEAR 7.0N 87.3E IS NOW LOCATED NEAR 7.5N 85.7E, APPROXIMATELY 462 NM 
SOUTHEAST OF CHENNAI, INDIA. ANIMATED ENHANCED INFRARED SATELLITE 
IMAGERY AND A 220418Z METOP-B 89GHZ MICROWAVE IMAGE REVEAL FORMATIVE 
BANDING WRAPPING INTO A CONSOLIDATING LOW LEVEL CIRCULATION CENTER 
WITH PERSISTENT CONVECTION. INVEST 97B IS CURRENTLY IN A FAVORABLE 
ENVIRONMENT FOR DEVELOPMENT WITH GOOD UPPER LEVEL OUTFLOW AND WARM 
(29-30C) SEA SURFACE TEMPERATURES BEING SLIGHTLY OFFSET BY MODERATE 
(15-20KTS) VERTICAL WIND SHEAR. GLOBAL MODELS ARE IN GOOD AGREEMENT 
THAT 97B WILL TRACK GENERALLY NORTHWESTWARD, INTENSIFYING TO WARNING 
THRESHOLD OVER THE NEXT TWO DAYS. MAXIMUM SUSTAINED SURFACE WINDS 
ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1005 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO 
MEDIUM.
      (3) 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: DISSIPATED AREA IN PARA 1.B.(1) AND 
UPGRADED AREA IN PARA 1.B.(2) TO MEDIUM.//
