SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND
/SOUTH PACIFIC OCEANS/290600Z-300600ZDEC2021//
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 97S) PREVIOUSLY LOCATED 
NEAR 16.1S 130.9E IS NOW LOCATED NEAR 16.6S 142.6E, APPROXIMATELY 
178 NM WEST OF CAIRNS, AUSTRALIA. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY (MSI) AND A 290424Z AMSR2 89GHZ SATELLITE IMAGE DEPICT 
DISORGANIZED CONVECTION OVER AN ELONGATED LOW LEVEL CIRCULATION 
(LLC). UPPER LEVEL ANALYSIS INDICATES MARGINAL CONDITIONS FOR 
DEVELOPMENT WITH ROBUST POLEWARD OUTFLOW OFFSET BY MODERATE (15-
20KT) VERTICAL WIND SHEAR. GLOBAL MODELS ARE IN GENERAL AGREEMENT 
THAT THE SYSTEM WILL TRACK EAST-SOUTHEASTWARD AND UNDERGO 
INTENSIFICATION UPON ENTERING THE CORAL SEA NEAR CAIRNS. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 997 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 
HOURS REMAINS MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
