SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH 
PACIFIC OCEANS/170600Z-180600ZFEB2023//
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 99W) PREVIOUSLY LOCATED NEAR 
5.7N 135.3E IS NOW LOCATED NEAR 7.7N 131.8E, APPROXIMATELY 163 NM WEST 
OF PALAU. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A 
BROAD, DISORGANIZED LOW-LEVEL CIRCULATION WITH DEEP CONVECTION OFFSET IN 
THE WESTERN SEMICIRCLE. INVEST 99W IS CURRENTLY POSITIONED ALONG THE 
SOUTHEASTERN EDGE OF AN EXTENSIVE NORTHEAST SURGE FLOW (25-30 KNOTS). 
ENVIRONMENTAL ANALYSIS INDICATES UNFAVORABLE CONDITIONS WITH HIGH (25-
40KT) EASTERLY VWS AND BROAD DIFLUENCE ALOFT. SST REMAINS CONDUCIVE AT A 
WARM 28-29C. GLOBAL MODELS ARE IN GENERAL AGREEMENT THAT 99W WILL HAVE 
LITTLE DEVELOPMENT AS IT TRACKS WEST-NORTHWESTWARD OVER THE NEXT 48 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. 
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 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:
      (1) THE AREA OF CONVECTION (INVEST 91P) PREVIOUSLY LOCATED NEAR 
15.0S 139.1E HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE DEVELOPMENT 
OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
