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 12MAR22 1800Z, TROPICAL CYCLONE 19S (GOMBE) WAS LOCATED 
NEAR 15.6S 35.1E, APPROXIMATELY 120 NM SOUTHEAST OF LILONGWE, 
MALAWI, AND HAD TRACKED WEST-SOUTHWESTWARD AT 07 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 
KNOTS GUSTING TO 35 KNOTS. SEE REF A (WTXS31 PGTW 122100) FOR THE 
FINAL WARNING ON THIS SYSTEM.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 90S) PREVIOUSLY LOCATED 
NEAR 11.0S 107.7E IS NOW LOCATED NEAR 13.1S 105.4E, APPROXIMATELY 
161 NM SOUTH OF CHRISTMAS ISLAND. ANIMATED ENHANCED MULTISPECTRAL 
SATELLITE DEPICTS DEEP CONVECTION OVERHEAD OF A LOW LEVEL 
CIRCULATION (LLC). A 130641Z AMSR2 89GHZ IMAGE REVEALS FORMATIVE 
FEEDER BANDS WRAPPING INTO THE LLC. A 100249Z BULLSEYE ASCAT-C PASS 
SHOWS 25 KNOT WINDS IN THE EASTERN PERIPHERY OF THE LLC.  IMAGERY 
ENVIRONMENTAL ANALYSIS INDICATES FAVORABLE CONDITIONS FOR 
DEVELOPMENT DEFINED BY; STRONG RADIAL OUTFLOW ALOFT, LOW (10-15KT) 
VERTICAL WIND SHEAR, AND WARM (28-29C) SEA SURFACE TEMPERATURES. 
GLOBAL MODELS ARE IN GOOD AGREEMENT THAT INVEST 90S WILL GENERALLY 
TRACK WEST-SOUTHWESTWARD, HOWEVER THEY ARE STILL SPLIT ON 
INTENSIFICATION WITH ECMWF SHOWING SLOWER DEVELOPMENT OVER THE NEXT 
24-48 HOURS.  MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 
28 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 130900) FOR FURTHER DETAILS.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(1) TO 
HIGH. //
