1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 03DEC20 1200Z, TROPICAL CYCLONE 05B (BUREVI) WAS 
LOCATED NEAR 9.4N 79.1E, APPROXIMATELY 956 NM SOUTHWEST OF KOLKATA, 
INDIA, AND HAD TRACKED WEST-NORTHWESTWARD AT 07 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 
KNOTS GUSTING TO 45 KNOTS. SEE REF A (WTIO31 PGTW 031500) FOR 
FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   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: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 95S) PREVIOUSLY LOCATED 
NEAR 6.5S 84.4E IS NOW LOCATED NEAR 6.9S 85.7E, APPROXIMATELY 785 NM 
EAST OF DIEGO GARCIA. ANIMATED ENHANCED INFRARED (EIR) SATELLITE 
IMAGERY AND A 040007Z MHS 89GHZ IMAGE DEPICT A DISORGANIZED, BUT 
CONSOLIDATING LOW LEVEL CIRCULATION CENTER WITH DEEP CONVECTION 
BUILDING ON THE EASTERN AND WESTERN PERIPHERIES. INVEST 95S IS 
CURRENTLY IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH GOOD 
EQUATORWARD OUTFLOW, WARM (28 TO 29 CELSIUS) SEA SURFACE 
TEMPERATURES AND LOW (<15 KTS) VERTICAL WIND SHEAR (VWS). GLOBAL 
MODELS ARE IN GOOD AGREEMENT THAT 95S WILL BEGIN TO TRACK GENERALLY 
SOUTH-SOUTHWESTWARD WITH STEADY 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 1004 MB. 
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE 
WITHIN THE NEXT 24 HOURS IS UPGRADED TO HIGH.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(1) TO HIGH.
