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 23JAN26 0000Z, TROPICAL CYCLONE 16P (SIXTEEN) WAS LOCATED 
NEAR 25.9S 177.0E, APPROXIMATELY 474 NM SOUTH OF SUVA, FIJI, AND HAD 
TRACKED EASTWARD AT 20 KNOTS OVER THE PAST SIX HOURS.THE WEAKENING 
LLCC AND HAD BECOME MORE ILL DEFINED AND CONVECTIVE COVERAGE CONTINUES 
TO DECREASE. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 
KNOTS GUSTING TO 45 KNOTS. SEE REF A (WTPS31 PGTW 230300) FOR THE 
FINAL WARNING ON THIS SYSTEM.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 90P) PREVIOUSLY LOCATED NEAR 
17.5S 152.4E HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.
      (2) AN AREA OF CONVECTION (INVEST 92P) HAS PERSISTED NEAR 13.2S 
140.4E, APPROXIMATELY 195 NM NORTHEAST OF MORINGTON ISLAND, AUSTRALIA. 
ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A FULLY 
OBSCURED LOW LEVEL CIRCULATION CENTER (LLCC) WITH DEEP CONVENTION 
BUILDING OVER THE CENTER AND VERY WELL DEFINED FORMATIVE BANDING ALONG 
THE NORTHERN PORTION OF THE CIRCULATION. RADAR IMAGERY FROM AUSTRALIA 
SHOWS A TIGHTENING VORTEX WITH THE LLCC LOCATED NEAR THE NORTHERN 
PERIPHERY OF THE CENTRAL CONVECTION. ENVIRONMENTAL CONDITIONS IN THE 
AREA ARE FAVORABLE WITH LOW (10-15KT) VERTICAL WIND SHEAR, WARM (28-
29C) SEA SURFACE TEMPERATURES AND GOOD POLEWARD OUTFLOW ALOFT. GLOBAL 
MODELS AGREE ON CONTINUED DEVELOPMENT IN THE GULF OF CARPENTARIA, WITH 
ECMWF SHOWING THE MOST INTENSIFICATION DURING THE NEXT 24 HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 28 TO 33 KNOTS. 
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN 
THE NEXT 24 HOURS REMAINS HIGH. SEE REF B (WTPS21 PGTW 230230)

      (3) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
