SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND
/SOUTH PACIFIC OCEANS/060600Z-070600ZFEB2022//
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) THE AREA OF CONVECTION (INVEST 92P) PREVIOUSLY LOCATED 
NEAR 17.7S 153.2E IS NOW LOCATED NEAR 18.4S 160.0E, APPROXIMATELY 
480NM WEST OF PORT VILA, VANUATU. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY CONTINUES TO DEPICT A POORLY-ORGANIZED AND ELONGATED 
DISTURBANCE EMBEDDED WITHIN A WEST-NORTHWEST TO EAST-SOUTHEAST 
ORIENTED FRONTAL TROUGH. A 060252Z AMSR2 36GHZ COLOR COMPOSITE 
MICROWAVE IMAGE REVEALS NO DISCERNIBLE LOW-LEVEL CIRCULATION WITH 
HIGHLY DISORGANIZED SHALLOW BANDS OF CONVECTION ACROSS THE CORAL 
SEA. THE DISTURBANCE IS LOCATED WITHIN MODERATE NORTHWESTERLY FLOW 
ALONG THE SOUTHWESTERN PERIPHERY OF AN UPPER-LEVEL RIDGE. VERTICAL 
WIND SHEAR REMAINS LOW TO MODERATE WITH WARM SEA SURFACE 
TEMPERATURES OF 29-30 DEGREES CELSIUS. THE DISTURBANCE IS EXPECTED 
TO TRACK EAST-SOUTHEASTWARD TOWARD VANUATU ALONG THIS FRONTAL 
BOUNDARY FOR THE NEXT 12 HOURS WITHIN A MARGINALLY FAVORABLE 
ENVIRONMENT. WITHIN THE NEXT 12 TO 24 HOURS, NUMERICAL MODELS 
GENERALLY AGREE THAT SOME DEVELOPMENT WILL OCCUR AS THE DISTURBANCE 
TRACKS UNDER A MORE FAVORABLE UPPER-LEVEL ENVIRONMENT BENEATH THE 
BROAD UPPER-LEVEL RIDGE. THIS ZONE WILL BE MONITORED CLOSELY, AS A 
COMPLEX ENVIRONMENT COULD LEAD TO MULTIPLE CIRCULATIONS FORMING IN 
CLOSE PROXIMITY WITHIN THE SOUTH PACIFIC CONVERGENCE ZONE IN THE 
GENERAL VICINITY OF NEW CALEDONIA, VANUATU, FIJI, AND TONGA DURING 
THE NEXT SEVERAL DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED 
AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE 
NEAR 999 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.//
