1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED NEAR 
13.1N 136.0E IS NOW LOCATED NEAR 13N 135.0E, APPROXIMATELY 277 NM 
NORTHWEST OF YAP. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) 
DEPICTS A BROAD AREA OF CYCLONIC ROTATION WITH FLARING CONVECTION. 
FURTHERMORE, A 210015Z ASCAT METOP-B IMAGE DEPICTS POORLY-DEFINED BROAD 
CYCLONIC CIRCULATION, WITH 15-20 KNOT WINDS IN THE SOUTHEASTERN 
QUADRANT. ENVIRONMENTAL ANALYSIS INDICATES THAT 92W IS IN A FAVORABLE 
ENVIRONMENT FOR DEVELOPMENT, WITH WARM (29-30C) SEA SURFACE 
TEMPERATURES, AND LOW (5-10KT) VWS AND GOOD DIVERGENCE ALOFT. GLOBAL 
MODELS ARE IN AGREEMENT THAT 92W WILL CONTINUE TO TRACK GENERALLY 
WESTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 13 TO 18 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 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 PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
