1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 04DEC20 1800Z, TROPICAL CYCLONE 05B (BUREVI) WAS 
LOCATED NEAR 9.0N 79.4E, APPROXIMATELY 130 NM NORTH-NORTHWEST OF 
COLOMO, SRI LANKA, AND HAD TRACKED WEST- NORTHWESTWARD AT 02 KNOTS 
OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE 
ESTIMATED AT 30 KNOTS GUSTING TO 40 KNOTS. SEE REF A (WTIO31 PGTW 
042100) FOR THE FINAL WARNING ON THIS SYSTEM.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
      (2) NO OTHER SUSPECT AREAS.
2. SOUTH INDIAN OCEAN AREA (135E WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 95S) PREVIOUSLY LOCATED 
NEAR 7.4S 84.9E IS NOW LOCATED NEAR 7.6S 84.7E, APPROXIMATELY 731 NM 
EAST OF DIEGO GARCIA. ANIMATED ENHANCED INFRARED (EIR) SATELLITE 
IMAGERY AND A 050114Z SSMIS 91GHZ IMAGE DEPICT A DISORGANIZED LOW 
LEVEL CIRCULATION WITH SOME WEAK FRAGMENTED CONVECTION. INVEST 95S 
IS CURRENTLY IN A MARGINALLY FAVORABLE ENVIRONMENT FOR DEVELOPMENT 
WITH SOME POLEWARD OUTFLOW, WARM (28 TO 29 CELSIUS) SEA SURFACE 
TEMPERATURES AND HIGH (>25 KTS) VERTICAL WIND SHEAR (VWS). GLOBAL 
MODELS ARE IN GOOD AGREEMENT THAT 95S WILL BEGIN TO TRACK GENERALLY 
SOUTH-SOUTHWESTWARD WITH GRADUAL INTENSIFICATION OVER THE NEXT 24 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 MB. 
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS REMAINS HIGH. SEE REF B (WTPS21 PGTW 
050330) FOR FURTHER DETAILS.
      (2) NO OTHER SUSPECT AREAS.
    C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: REISSUED TROPICAL CYCLONE FORMATION 
ALERT FOR AREA IN PARA 2.B.(1).//
