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 01MAR22 0000Z, TROPICAL CYCLONE 14S (VERNON) WAS 
LOCATED NEAR 14.3S 87.2E, APPROXIMATELY 968 NM EAST-SOUTHEAST OF 
DIEGO GARCIA, AND HAD TRACKED SOUTH- SOUTHWESTWARD AT 03 KNOTS OVER 
THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED 
AT 45 KNOTS GUSTING TO 55 KNOTS. SEE REF A (WTXS31 PGTW 010300) FOR 
FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (REMNANTS OF 15S) PREVIOUSLY 
LOCATED NEAR 16.5S 125.0E IS NOW LOCATED NEAR 17.6S 123.3E, 
APPROXIMATELY 308 NM SOUTH-SOUTHWEST OF WYNDHAM. ANIMATED ENHANCED 
MULTISPECTRAL SATELLITE IMAGERY AND A 282216Z 91GHZ IMAGE DEPICT 
BROAD CONVECTION OVERHEAD A LOW LEVEL CIRCULATION (LLC) THAT IS 
CURRENTLY OVER LAND.  ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE 
CONDITIONS FOR DEVELOPMENT DEFINED BY ROBUST OUTFLOW ALOFT, LOW TO 
MODERATE (15-20KT) VERTICAL WIND SHEAR, AND THE POTENTIAL FOR WARM 
(29-30C) SEA SURFACE TEMPERATURES ONCE THE CENTER MOVES BACK OVER 
WATER. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT TC 15S WILL TRACK 
WESTWARD ALONG THE NORTHWESTERN COAST OF AUSTRALIA BEFORE EMERGING 
OVER THE INDIAN OCEAN AROUND TAU 18 AND THEN REACH WARNING CRITERIA. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 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. SEE REF B (WTXS21 PGTW 
010300) FOR FURTHER DETAILS.
      (2) THE AREA OF CONVECTION (INVEST 95S) PREVIOUSLY LOCATED 
NEAR 10.4S 109.9E IS NOW LOCATED NEAR 10.5S 111.5E, APPROXIMATELY 
341 NM EAST OF CHRISTMAS ISLAND. ANIMATED ENHANCED MULTISPECTRAL 
SATELLITE IMAGERY DEPICTS SOME CONVECTION OVERHEAD A PARTIALLY 
EXPOSED LOW LEVEL CIRCULATION. ENVIRONMENTAL ANALYSIS INDICATES 
MARGINALLY FAVORABLE CONDITIONS FOR DEVELOPMENT WITH POLEWARD 
OUTFLOW ALOFT AND WARM (29-30C) SEA SURFACE TEMPERATURES; OFFSET BY 
MODERATE TO HIGH (20-25KT) VERTICAL WIND SHEAR. GLOBAL MODELS ARE 
STILL IN AGREEMENT THAT 95S WILL HAVE LITTLE DEVELOPMENT AS IT 
TRACKS SOUTHEASTWARD OVER THE NEXT 24-48 HOURS.  MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL 
PRESSURE IS ESTIMATED TO BE NEAR 1010 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 
HOURS REMAINS LOW.
      (3) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(1) TO 
HIGH.//
