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:
      (1) AT 12DEC20 1800Z, TROPICAL CYCLONE 05P (FIVE) WAS LOCATED 
NEAR 14.2S 173.7E, APPROXIMATELY 358 NM NORTHWEST OF SUVA, FIJI, AND 
HAD TRACKED SOUTH-SOUTHEASTWARD AT 09 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING 
TO 45 KNOTS. SEE REF A (WTPS31 PGTW 122100) FOR THE FINAL WARNING ON 
THIS SYSTEM.
      (2) AT 12DEC20 1200Z, TROPICAL CYCLONE 04P (FOUR) WAS LOCATED 
NEAR 15.7S 173.1E, APPROXIMATELY 337 NM WEST-NORTHWEST OF SUVA, 
FIJI, AND HAD TRACKED WESTWARD AT 14 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING 
TO 45 KNOTS. SEE REF B (WTPS33 PGTW 121500) FOR THE FINAL WARNING ON 
THIS SYSTEM.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 92P) PREVIOUSLY LOCATED 
NEAR 14.0S 170.3W IS NOW LOCATED NEAR 15.8S 170.9W, APPROXIMATELY 91 
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 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 1006 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN 
THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(1) TO 
MEDIUM.//
