SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH 
PACIFIC OCEANS/240600Z-250600ZFEB2023//
RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   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) AN AREA OF CONVECTION (INVEST 94P) HAS PERSISTED NEAR 14.8S 
175.8E, APPROXIMATELY 300 NM WEST OF PAGO PAGO, AMERICAN SAMOA. ANIMATED 
MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A FULLY EXPOSED LOW LEVEL 
CIRCULATION (LLC) WITH BUILDING CONVECTION IN THE NORTHERN AND EASTERN 
QUADRANTS. THIS CIRCULATION APPEARS TO BE A SPINNER ASSOCIATED WITH A 
MUCH BROADER AREA OF TROUGHING AS INDICATED ON A RECENT SCATTEROMETRY 
IMAGE. ENVIRONMENTAL ANALYSIS REVEALS THAT INVEST 94P IS IN A MARGINAL 
AREA FOR TROPICAL DEVELOPMENT CHARACTERIZED BY MODERATE (35-40 KTS) 
EQUATORWARD UPPER LEVEL OUTFLOW, A GOOD 850MB VORTICITY SIGNATURE, VERY 
WARM (29-30) SEA SURFACE TEMPERATURES (SSTS), OFFSET BY HIGH (30-40 KTS) 
VERTICAL WIND SHEAR (VWS). ALTHOUGH INVEST 94P IS NOT TOO IMPRESSIVE ON 
SATELLITE, NAVGEM, ICON, AND GFS DETERMINISTIC ALONG WITH GEFS ENSEMBLE 
GUIDANCE SHOWS THE DISTURBANCE HEADING WESTWARD INTO A MORE FAVORABLE 
ENVIRONMENT AND CONSOLIDATING OVER THE NEXT 48-72 HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS 
LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
