1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 04MAR22 1800Z, TROPICAL CYCLONE 01B (ONE) WAS LOCATED 
NEAR 11.1N 83.6E, APPROXIMATELY 743 NM SOUTH-SOUTHWEST OF KOLKATA, 
INDIA, AND HAD TRACKED NORTH- NORTHEASTWARD AT 09 KNOTS OVER THE 
PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 
KNOTS GUSTING TO 45 KNOTS. SEE REF A (WTIO31 PGTW 042100) FOR 
FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 90B) PREVIOUSLY LOCATED 
NEAR 9.4N 83.1E IS NOW THE SUBJECT OF A TROPICAL CYCLONE WARNING. 
SEE PARA. 1.A.(1) FOR FURTHER DETAILS.
      (2) NO OTHER SUSPECT AREAS.
   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 97S) PREVIOUSLY LOCATED 
NEAR 15.6S 55.9E IS NOW LOCATED NEAR 15.7S 55.7E, APPROXIMATELY 303 
NM EAST OF MADAGASCAR. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
(MSI) AND A 041515Z SSMIS 91GHZ MICROWAVE IMAGE DEPICT A 
CONSOLIDATING LOW LEVEL CIRCULATION (LLC) OBSCURED BY FLARING 
CONVECTION WITH FRAGMENTED BANDING BEGINNING TO WRAP INTO THE 
DISTURBANCE. UPPER LEVEL ANALYSIS INDICATES FAVORABLE CONDITIONS FOR 
DEVELOPMENT TO INCLUDE GOOD OUTFLOW ALOFT, LOW TO MODERATE VERTICAL 
WIND SHEAR (10-20KTS), AND WARM SEA SURFACE TEMPRETURES (28-29C). 
GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 97S WILL REMAIN GENERALLY 
QUASI-STATIONARY AS IT STEADILY INTENSIFIES EAST OF MADAGASCAR. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. 
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 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: UPGRADED AREA IN PARA 1.B.(1) TO 
WARNING STATUS.//
