SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND
/SOUTH PACIFIC OCEANS/080600Z-090600ZDEC2021//
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 93P) HAS PERSISTED NEAR 9.7S 
156.2E, APPROXIMATELY 225 NM WEST OF HONIARA, SOLOMON ISLANDS. 
ANIMATED ENHANCED MULTISPECTRAL SATELLITE IMAGERY DISPLAYS LOW LEVEL 
CLOUD LINES WRAPPING INTO A BROAD LLCC (LOW LEVEL CIRCULATION 
CENTER) WITH FLARING, DISORGANIZED CONVECTION. A 072251Z METOP-C 
PASS SHOWS 10-15KT WINDS AROUND A LARGE CIRCULATION CENTER. 
ENVIRONMENTAL ANALYSIS REVEALS THAT THE CIRCULATION IS IN AN AREA OF 
MARGINALLY FAVORABLE DEVELOPMENT DEFINED BY WARM SST (30-31C) AND 
LOW TO MODERATE VERTICAL WIND SHEAR. THE OUTFLOW IS NOTABLE WITH 
ENHANCED POLEWARD OUTFLOW FEEDING INTO THE JET TO THE SOUTH. GLOBAL 
MODELS ARE IN AGREEMENT THAT THE SYSTEM WILL GENERALLY TRACK 
SOUTHEASTWARD OVER THE NEXT 24-48 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 IS LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
