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: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 92S) PREVIOUSLY LOCATED 
NEAR 32.0S 30.5E, IS NOW LOCATED NEAR 30.5S 30.7E, APPROXIMATELY 291 
NM SOUTHWEST OF MAPUTO, MOZAMBIQUE. THE SYSTEM IS CURRENTLY 
CLASSIFIED AS A SUBTROPICAL STORM, GENERALLY CHARACTERIZED AS HAVING 
BOTH TROPICAL AND MIDLATITUDE CYCLONE FEATURES. ENHANCED ANIMATED 
INFRARED SATELLITE IMAGERY DEPICTS A WEAK ILL DEFINED LOW LEVEL 
CIRCULATION WITH A LACK OF CONVECTION. ENVIRONMENTAL ANALYSIS 
REVEALS UNFAVORABLE CONDITIONS FOR DEVELOPMENT DEFINED BY; WEAK 
OUTFLOW ALOFT, HIGH (20-30KT) VERTICAL WIND SHEAR, AND COOL (25-26C) 
SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 
INVEST 92S WILL WEAKEN AS IT TRACKS EASTWARD OVER THE NEXT 12 TO 24 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1000 MB. 
IN VIEW OF THE UNFAVORABLE FORECAST FOR THIS SYSTEM, IT IS NO LONGER 
CONSIDERED SUSPECT FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL 
CYCLONE WITHIN THE NEXT 24 HOURS.  SEE REF A (WTXS21 PGTW 131800) 
FOR FURTHER DETAILS.
      (2) NO OTHER SUBTROPICAL SYSTEMS.//
