REF/A/MSG/JOINT TYPHOON WRNCEN PEARL HARBOR HI/130151ZDEC2020//
AMPN/REF A IS A TROPICAL CYCLONE WARNING.//
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) NO OTHER SUSPECT AREAS.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 13DEC20 0000Z, TROPICAL CYCLONE 05P (FIVE) WAS LOCATED 
NEAR 15.1S 173.3E, APPROXIMATELY 327 NM EAST-NORTHEAST OF PORT VILA, 
VANUATU, AND HAD TRACKED SOUTH- SOUTHWESTWARD AT 10 KNOTS (KTS) OVER 
THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 
40 KNOTS GUSTING TO 50 KNOTS. SEE REF A (WTPS31 PGTW 130300) FOR 
FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 92P) PREVIOUSLY LOCATED NEAR
15.8S 170.9W IS NOW LOCATED NEAR 16.1S 171.5W, APPROXIMATELY 122 NM 
SOUTH-SOUTHWEST OF PAGO PAGO, AMERICAN SAMOA. ANIMATED MULTISPECTRAL 
SATELLITE IMAGERY (MSI) INDICATES LOW LEVEL BANDING WRAPPING INTO A LOW 
LEVEL CIRCULATION CENTER OBSCURED BY DEEP CONVECTION. A 122104Z METOP-B 
89GHZ SATELLITE IMAGE REVEALS AN AREA OF DEEP CONVECTION OVER THE EASTERN 
PERIPHERY. A 122105Z ASCAT-B PASS REVEALS A DEFINED CIRCULATION WITH A 
SWATH OF 30-34 KT WINDS UNDER THE PREVIOUSLY MENTIONED CONVECTION WITH 
WEAKER WINDS ELSEWHERE. ENVIRONMENTAL ANALYSIS INDICATES INVEST 92P IS IN 
AN AREA CONDUCIVE FOR DEVELOPMENT WITH EQUATORWARD AND POLEWARD OUTFLOW, 
LOW (10-15 KTS) VERTICAL WIND SHEAR (VWS) AND WARM (28-29 CELSIUS) SEA 
SURFACE TEMPERATURE (SST). GLOBAL MODELS ARE IN GOOD AGREEMENT THAT INVEST 
92P WILL CONTINUE TO CONSOLIDATE AND TRACK WEST-SOUTHWESTWARD OVER THE 
NEXT 24 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE 
NEXT 24 HOURS IS UPGRADED TO HIGH.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
