SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH 
PACIFIC OCEANS/180600Z-190600ZJUL2026//
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 90W) PREVIOUSLY LOCATED NEAR 
7.2N 152.5E IS NOW LOCATED NEAR 8.2N 155.7E, APPROXIMATELY 166 NM WEST-
NORTHWEST OF POHNPEI. ANIMATED ENHANCED MULTISPECTRAL IMAGERY (MSI) 
DEPICTS A BROAD AREA OF CYCLONIC TURNING WITH FLARING CONVECTION 
DISPLACED TO THE EAST OF THE ASSESSED CIRCULATION. UPPER-LEVEL ANALYSIS 
INDICATES THAT 90W IS IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT, WITH 
LOW (5-10 KNOT) VWS, GOOD DIVERGENCE ALOFT, AND WARM (29-30C) SEA 
SURFACE TEMPERATURES. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 90W WILL 
CONTINUE GENERALLY NORTH OVER THE NEXT 24-48 HOURS BEFORE SHIFTING TO A 
NORTHWESTWARD TRACK AS IT CONSOLIDATES OVER THE NEXT 72-96 HOURS. WHILE 
THE CONDITIONS ARE OVERALL FAVORABLE, THE LACK OF A DISTINCT AND DEFINED 
LLCC WILL SERVE TO LIMIT FURTHER DEVELOPMENT AT THIS TIME, THOUGH 
WESTERLY SURFACE WINDS EQUATORWARD OF THE SYSTEM ARE ELEVATED. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28 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 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.//
