1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 19JAN26 0600Z, TROPICAL STORM 01W (NOKAEN) WAS LOCATED 
NEAR 16.7N 126.6E, APPROXIMATELY 347 NM EAST-NORTHEAST OF MANILA, 
PHILIPPINES, AND HAD TRACKED NORTHEASTWARD AT 01 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS 
GUSTING TO 45 KNOTS. SEE REF A (WTPN31 PGTW 190900) FOR FURTHER 
DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   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) THE AREA OF CONVECTION (INVEST 94P) PREVIOUSLY LOCATED NEAR 
17.1S 158.1E IS NOW LOCATED NEAR 17.1S 159.3E, APPROXIMATELY 510 NM 
NORTHWEST OF NOUMEA, NEW CALEDONIA. ANIMATED ENHANCED INFRARED 
SATELLITE IMAGERY (EIR) DEPICTS A SLOWLY CONSOLIDATING LOW LEVEL 
CIRCULATION CENTER (LLCC), WITH DEEP AND PERSISTENT CONVECTION 
BUILDING OVER THE CENTER. A 191048Z METOP-C ASCAT REVEALS 18-23 KNOT 
WINDS WRAPPING AROUND THE EASTERN QUADRANT OF 94P.  IN ADDITION, A 
LARGE SWATH OF WINDS UP TO 25 KTS ARE OBSERVED 112 NM AND DISLOCATED 
TO THE NORTHWEST OF THE ASSESSED CIRCULATION CENTER. ENVIRONMENTAL 
ANALYSIS FOR THE AREA INDICATES A FAVORABLE ENVIRONMENT FOR 
DEVELOPMENT, WITH LOW VERTICAL WIND SHEAR (10-15 KT), WARM SEA SURFACE 
TEMPERATURES (27-28 C), AND WEAK EQUATORWARD OUTFLOW ALOFT. GLOBAL 
DETERMINISTIC AND ENSEMBLE MODELS SHOW ONGOING SUPPORT FOR 94P TO 
REACH WARNING CRITERIA OF 35 KTS IN THE NEXT 12-24 HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 997 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS 
IS UPGRADED TO HIGH. SEE REF B (WTPS21 PGTW 191230) FOR FURTHER 
DETAILS.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(1) TO HIGH.//
