1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 93A) HAS PERSISTED NEAR 
14.8N 69.1E, APPROXIMATELY 330 NM SOUTHWEST OF MUMBAI, INDIA. 
ANIMATED ENHANCED INFRARED SATELLITE IMAGERY (EIR) AND A TIMELY 
162359Z SSMIS 91GHZ MICROWAVE IMAGE DEPICTS A POORLY ORGANIZED LLC 
WITH MOST OF THE CONVECTION SHEARED TO THE NORTHWESTERN PERIPHERY. 
UPPER LEVEL ANALYSIS INDICATES A FAVORABLE ENVIRONMENT WITH LOW TO 
MODERATE (10 TO 20 KTS) VWS, EXCELLENT POLEWARD OUTFLOW AND WARM (28-
29C) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN AGREEMENT THAT 
INVEST 93A WILL SEE MINIMAL DEVELOPMENT AS IT TRACKS WEST-
NORTHWESTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 12 
TO 17 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1010 
MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL 
CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH INDIAN OCEAN AREA (135E WEST TO COAST OF AFRICA):
