1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 18DEC23 1200Z, TROPICAL DEPRESSION 18W (JELAWAT) WAS 
LOCATED NEAR 7.3N 125.2E, APPROXIMATELY 18 NM EAST-NORTHEAST OF DAVAO, 
PHILIPPINES, AND HAD TRACKED WESTWARD AT 07 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 KNOTS 
GUSTING TO 35 KNOTS. SEE REF A (WTPN31 PGTW 181500) FOR THE FINAL 
WARNING ON THIS SYSTEM.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED NEAR 
3.5N 166.8E IS NOW LOCATED NEAR 3.7N 167.6E, APPROXIMATELY 292 NM EAST-
SOUTHEAST OF KOSRAE. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 
180208Z AMSR2 89GHZ MICROWAVE IMAGE DEPICT DEEP CONVECTIVE LINES ON THE 
EQUATORWARD SIDE OF AN ELONGATED SOUTHWEST TO NORTHEAST ORIENTATED 
TROUGH. ENVIRONMENTAL ANALYSIS REVEALS MARGINALLY FAVORABLE CONDITIONS 
FOR INTENSIFICATION DUE TO LOW TO MODERATE (15-20KT) VWS AND FAIR DUEL-
CHANNEL OUTFLOW, OFFSET BY WARM (28-29C) SEA SURFACE TEMPERATURES. 
NUMERICAL MODELS SHOW A MIXED PICTURE BETWEEN GOOD DEVELOPMENT AND 
MEANDERING MOTION, BUT AGREE ON A GENERALLY WESTWARD TRAJECTORY.  
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 13 TO 17 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 REMAINS LOW.
      (2) NO OTHER SUSPECT AREAS.
   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: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPDATED PARA 1.A.(1) WITH FINAL WARNING
