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 30MAR22 1200Z, TROPICAL CYCLONE 22S (HALIMA) WAS 
LOCATED NEAR 19.7S 82.3E, APPROXIMATELY 947 NM SOUTHEAST OF DIEGO 
GARCIA, AND HAD TRACKED NORTH-NORTHEASTWARD AT 02 KNOTS OVER THE 
PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 40 
KNOTS GUSTING TO 50 KNOTS. SEE REF A (WTXS32 PGTW 301500) FOR 
FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 96S) PREVIOUSLY LOCATED 
NEAR 15.6S 109.3E IS NOW LOCATED NEAR 16.8S 110.8E, APPROXIMATELY 
369 NM NORTHWEST OF LEARMONTH, AUSTRALIA. ANIMATED MULTISPECTRAL 
IMAGERY (MSI) DEPICTS BROAD ISOLATED CONVECTION OFFSET TO THE 
SOUTHEAST OF A WEAK ELONGATED LOW LEVEL CIRCULATION (LLC). THE 
TROPICAL ENVIRONMENT IS FAVORABLE WITH MODERATE POLEWARD OUTFLOW, 
LOW (5-10KTS) VERTICAL WIND SHEAR, AND WARM (29-30C) SEA SURFACE 
TEMPERATURES. GLOBAL MODELS AGREE ON A SIMILAR TRACK WITH 96S MOVING 
SOUTH-SOUTHEAST OVER THE NEXT 48 HOURS, WITH GFS, CMC, AND ECMWF 
GLOBAL FIELDS DEPICTING A SMALL AREA OF STRONG WINDS ALONG THE 
EASTERN PERIPHERY AS IT SKIRTS ALONG THE COAST NEAR LEARMONTH, 
AUSTRALIA. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 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.//
