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 92B) PREVIOUSLY LOCATED NEAR 
11.7N 93.1E IS NOW LOCATED NEAR 10.3N 96.7E, APPROXIMATELY 253 NM 
EAST-SOUTHEAST OF PORT BLAIR, ANDAMAN ISLANDS. ANIMATED ENHANCED 
INFRARED SATELLITE IMAGERY (EIR) SHOWS A PERSISTENT, DISORGANIZED 
DISTURBANCE IN THE SOUTHEASTERN REGION OF THE ANDAMAN SEA WRAPPING 
INTO A WEAK, ELONGATED, AND ILL-DEFINED LOW LEVEL CIRCULATION (LLC). A 
PARTIAL 181523Z ASCAT-B SHOWS THE WESTERN EDGE OF THE LLC WITH SOME 
20KT WIND BARBS ALONG THE SOUTHERN PERIPHERY. UPPER LEVEL ANALYSIS 
INDICATES INVEST 92B IS IN AN AREA WITH LOW (10-15 KT) VWS, MODERATE 
DIVERGENCE AND POLEWARD OUTFLOW. WARM SEA SURFACE TEMPERATURES AT 28-
29C. OVERALL, THE ENVIRONMENT IS OVERALL JUST MARGINALLY FAVORABLE. 
GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 92B WILL CONTINUE TO TRACK 
GENERALLY NORTHWESTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED 
AT 20 TO 25 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 LOW.
      (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.
