SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH 
PACIFIC OCEANS/270600Z-280600ZAUG2022//
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 90W) PREVIOUSLY LOCATED NEAR 
24.1N 151.3E IS NOW LOCATED NEAR 22.5N 150.1E, APPROXIMATELY 500 NM EAST-
SOUTHEAST OF IWO-TO. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY DEPICTS 
A NORTHWEST TO SOUTHEAST ORIENTED OPEN WAVE WITH DEEP CONVECTION IN THE 
EASTERN PERIPHERY. A 270000Z ASCAT-C PARTIAL PASS REVEALS A SWATH OF 20- 
25 KT WINDS TO THE EAST OF THE OPEN WAVE. ENVIRONMENTAL ANALYSIS REVEALS 
FAVORABLE CONDITIONS FOR DEVELOPMENT DEFINED BY DIVERGENCE ALOFT, LOW (5-
10KT) VERTICAL WIND SHEAR AND WARM (30-31C) SEA SURFACE TEMPERATURES. 
GLOBAL MODELS HAVE BACKED OFF ON THE DEVELOPMENT OF 90W BUT ARE STILL IN 
GENERAL AGREEMENT THAT IT WILL TRACK NORTH-NORTHWESTWARD. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 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.//
