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 99B) PREVIOUSLY LOCATED NEAR 
7.5N 82.7E IS NOW LOCATED NEAR 8.3N 82.4E, APPROXIMATELY 174 NM EAST-
NORTHEAST OF COLOMBO, SRI LANKA. ANIMATED ENHANCED INFRARED SATELLITE 
IMAGERY (EIR), AS WELL AS A 261229Z 91GHZ SSMIS IMAGE, DEPICT CURVED 
DEEP CONVECTIVE BANDING CONSOLIDATING NORTH OF THE CIRCULATION. A 
PARTIAL 261508Z ASCAT METOP-B PASS INDICATES THE AREA OF CONVECTION 
HAS A SYMMETRICAL STRENGTHENING CIRCULATION WITH 30 KNOT WINDS ON THE 
EASTERN PERIPHERY OF THE CIRCULATION. ENVIRONMENTAL ANALYSIS INDICATES 
A FAVORABLE ENVIRONMENT FOR FURTHER DEVELOPMENT WITH GOOD UPPER-LEVEL 
DIVERGENCE, WARM SEA SURFACE TEMPERATURES (29-30C), SYMMETRIC 850 MB 
VORTICITY, AND LOW TO MODERATE UPPER LEVEL WIND SHEAR (15-20KTS). 
GLOBAL DETERMINISTIC MODELS ARE IN GOOD AGREEMENT THAT INVEST 99B WILL 
CONSOLIDATE AND STRENGTHEN OVER THE NEXT 24 HOURS. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 28 TO 33 KNOTS. MINIMUM SEA LEVEL 
PRESSURE IS ESTIMATED TO BE NEAR 998 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:
      (1) AT 27NOV24 1200Z, TROPICAL CYCLONE 03S (THREE) WAS LOCATED 
NEAR 12.7S 91.2E, APPROXIMATELY 1155 NM EAST-SOUTHEAST OF DIEGO 
GARCIA, AND HAD TRACKED SOUTH- SOUTHWESTWARD AT 08 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS 
GUSTING TO 45 KNOTS. SEE REF A (WTXS31 PGTW 271500) FOR FURTHER 
DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 96S) PREVIOUSLY LOCATED NEAR 
9.7S 93.5E IS NOW THE SUBJECT OF A TROPICAL CYCLONE WARNING. SEE PARA. 
2.A.(1) FOR FURTHER DETAILS.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.A.(1) TO WARNING 
STATUS.//
