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: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 97S) PREVIOUSLY LOCATED 
NEAR 12.0S 44.9E IS NOW LOCATED NEAR 13.8S 42.6E, APPROXIMATELY 119 
NM EAST-NORTHEAST OF NACALA, MOZAMBIQUE. ANIMATED INFRARED SATELLITE 
IMAGERY SHOWS FLARING CONVECTION OVER A DEVELOPING LOW LEVEL 
CIRCULATION CENTER. A 221606Z SSMIS 91GHZ IMAGE DEPICTS FORMATIVE 
BANDING DEVELOPING ALONG THE SOUTHERN AND WESTERN PERIPHERIES OF THE 
CONSOLIDATING SYSTEM. ENVIRONMENTAL ANALYSIS SHOWS INVEST 97S IS 
POSITIONED NEAR AN UPPER-LEVEL LOW THAT PROVIDES INCREASED OUTFLOW 
AND LOW-MODERATE (10-20KT) VWS. GLOBAL MODELS INDICATE CONTINUED 
DEVELOPMENT AS THE CIRCULATION TRACKS SOUTHWESTWARD, WITH POTENTIAL 
LANDFALL IN 12 TO 24 HOURS AS A LIMITING FACTOR. 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 REMAINS MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
