SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH 
PACIFIC OCEANS/180600Z-190600ZJUN2026//
RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED NEAR 
10.4N 154.4E IS NOW LOCATED NEAR 12.0N 147.7E, APPROXIMATELY 195 NM 
EAST-SOUTHEAST OF NAVAL STATION GUAM. ANIMATED ENHANCED MULTISPECTRAL 
SATELLITE IMAGERY (EIR) DEPICTS FLARING CONVECTION NEAR A SLOWLY 
CONSOLIDATING LOW-LEVEL CIRCULATION CENTER (LLCC). A PARTIAL 180023Z 
METOP-C ASCAT PASS, WHICH SAMPLED THE NORTHERN AND WESTERN QUADRANTS OF 
THE SYSTEM, SHOWED 15-20 KNOT WINDS ALONG THE NORTHERN PERIPHERY. 
ENVIRONMENTAL ANALYSIS INDICATES CONDITIONS FAVORABLE FOR DEVELOPMENT, 
WITH LOW VERTICAL WIND SHEAR (5-10 KTS), MODERATE POLEWARD OUTFLOW 
ALOFT, AND WARM SEA SURFACE TEMPERATURES (29-30 C). GLOBAL DETERMINISTIC 
AND ENSEMBLE GUIDANCE GENERALLY AGREE ON GRADUAL DEVELOPMENT OVER THE 
NEXT 48 HOURS AS THE SYSTEM CONSOLIDATES WHILE TRACKING WEST-
NORTHWESTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN 
THE NEXT 24 HOURS REMAINS MEDIUM.
      (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.//
