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:
      (1) AT 02JAN26 1200Z, TROPICAL CYCLONE 09S (GRANT) WAS LOCATED 
NEAR 15.2S 66.6E, APPROXIMATELY 597 NM SOUTHWEST OF DIEGO GARCIA, AND 
HAD TRACKED NORTHWESTWARD AT 05 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO 45 
KNOTS. SEE REF A (WTXS32 PGTW 021500) FOR FURTHER DETAILS.
      (2) AT 02JAN26 1800Z, TROPICAL CYCLONE 11S (IGGY) WAS LOCATED 
NEAR 16.8S 108.2E, APPROXIMATELY 469NM NORTHWEST OF LEARMONTH, 
AUSTRALIA, AND HAD TRACKED WEST- SOUTHWESTWARD AT 06 KNOTS OVER THE 
PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 30 
KNOTS GUSTING TO 40 KNOTS. SEE REF B (WTXS31 PGTW 022100) FOR THE 
FINAL WARNING ON THIS SYSTEM.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 91S) HAS PERSISTED NEAR 10.0S 
88.3E, APPROXIMATELY 524 NM WEST-NORTHWEST OF THE COCOS ISLANDS. 
ANIMATED ENHANCED INFRARED SATELLITE IMAGERY DEPICTS STEADILY BUILDING 
CONVECTION ASSOCIATED WITH A COMPACT LOW LEVEL CIRCULATION. A 021504Z 
METOP-B SCATTEROMETRY IMAGE VERIFIES THAT A DEVELOPING CIRCULATION 
EMBEDDED WITHIN THE SOUTHERN MONSOON TROF IS CONSOLIDATING, AND 
DEEPENING CONVECTION AROUND THE SYSTEM. ENVIRONMENTAL ANALYSIS REVEALS 
FAVORABLE CONDITIONS FOR DEVELOPMENT WITH LOW TO MODERATE VERTICAL 
WIND SHEAR (10-15 KTS), WARM SEA SURFACE TEMPERATURES (28-29 C), AND 
GOOD POLEWARD AND EQUATORWARD OUTFLOW ON THE WESTERN PERIPHERY BUT 
RESTRICTED OUTFLOW ON THE EASTERN SIDE. GLOBAL DETERMINISTIC AND 
ENSEMBLE MODELS SHOW GOOD AGREEMENT ON STEADY CONSOLIDATION OVER THE 
FOLLOWING COUPLE OF DAYS WITH ALL MODELS SHOWING DEVELOPMENT. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS 
REMAINS LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPDATED AREA IN PARA. 2.A.(2) WITH FINAL 
WARNING INFORMATION.//
