SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH 
PACIFIC OCEANS/260600Z-270600ZMAR2026//
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. 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:
      (1) THE AREA OF CONVECTION (INVEST 22P) PREVIOUSLY LOCATED NEAR 
37.5S 165.3E IS NOW LOCATED NEAR 39.0S 166.1E, APPROXIMATELY 776 NM 
EAST-SOUTHEAST OF PORT KEMBLA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
(MSI) DEPICTS A BROAD YET DEFINED LOW-LEVEL CIRCULATION WITH WEAK 
CONVECTION CONTINUING TO FLARE NEAR THE CENTER. A DEVELOPING FRONTAL 
FEATURE CAN BE SEEN EXTENDING EQUATORWARD ALONG THE EASTERN SIDE OF THE 
SYSTEM. ENVIRONEMNTAL ANALYSIS INDICATES HIGHLY UNFAVORABLE CONDITIONS 
FOR TROPICAL DEVELOPMENT CHARACTERIZED BY COLD (20-21 C) SEA SURFACE 
TEMPERATURES, HIGH (30-35 KTS) NORTHWESTERLY VERTICAL WIND SHEAR, AND 
SIGNIFICANT DRY AIR ENTRAINMENT. NUMERICAL MODEL GUIDANCE AGREES ON A 
SOUTHWARD TRACK, TOWARD SOUTHERN NEW ZEALAND, OVER THE NEXT 24 HOURS 
WITH GALE FORCE WINDS PERSISTING PRIMARILY WITHIN THE SOUTHEASTERN 
QUADRANT. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 38 TO 43 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 984 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN 
THE NEXT 24 HOURS REMAINS LOW.
      (2) NO OTHER SUBTROPICAL SYSTEMS.//
