RMKS/
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 
13.3N 126.5E IS NOW LOCATED NEAR 15.2N 123.3E, APPROXIMATELY 139 NM 
EAST-NORTHEAST OF MANILA, PHILIPPINES. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY (MSI) DEPICTS LITTLE TO NO CONVECTIVE ACTIVITY ASSOCIATED WITH 
THE EXTREMELY BROAD LOW-LEVEL CIRCULATION (LLC) THAT IS SLOWLY 
TRANSITING TOWARD CENTRAL LUZON. A 080032Z ASCAT-B 25KM IMAGE DEPICTS 
THE ELONGATED NATURE OF THE CIRCULATION WITH 10 KNOT WINDS ALONG THE 
NORTHERN AND EASTERN PERIPHERIES OF THE SYSTEM. ENVIRONMENTAL ANALYSIS 
REVEALS A MODERATELY FAVORABLE ENVIRONMENT, WITH MODERATE EQUATORWARD 
OUTFLOW ALOFT AND LOW TO MODERATE VERTICAL WIND SHEAR (VWS) OF 15-20 
KNOTS. 92W WILL ALSO HAVE WARM SEA SURFACE TEMPERATURES OF 30-31C TO 
HELP DEVELOPMENT. GLOBAL DETERMINISTIC AND ENSEMBLE MODELS ARE CURRENTLY 
IN GOOD AGREEMENT ON A WESTWARD TRACK INTO THE SOUTH CHINA SEA OVER THE 
NEXT 48 HOURS WITH STEADY INTENSIFICATION AS THE SYSTEM CONSOLIDATES. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 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 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.//
