1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 99B) PREVIOUSLY LOCATED NEAR 
14.0N 83.6E IS NOW LOCATED NEAR 13.7N 86.9E, APPROXIMATELY 360 NM WEST-
NORTHWEST OF PORT BLAIR. ANIMATED ENHANCED INFRARED (EIR) SATELLITES 
IMAGERY DEPICTS A BROAD SLOWLY CONSOLIDATING CIRCULATION AND POORLY 
DEFINED LLC. ENVIRONMENTAL ANALYSIS INDICATES A MARGINALLY FAVORABLE 
ENVIRONMENT FOR DEVELOPMENT DUE TO MODERATE (15-20KT) VWS, OFFSET BY GOOD 
EQUATORWARD OUTFLOW, AND WARM (30-31C) SST. GLOBAL DETERMINISTIC MODELS 
ARE IN GOOD AGREEMENT THAT 99B WILL CONTINUE TO STRENGTHEN IN THE BAY OF 
BENGAL OVER THE NEXT 24 HRS. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO 
BE NEAR 1001 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT 
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.
      (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: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
