SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH 
PACIFIC OCEANS REISSUED/260000Z-260600ZMAY2026//
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 99W) PREVIOUSLY LOCATED NEAR 
7.5N 141.7E IS NOW LOCATED NEAR 8.4N 138.8E, APPROXIMATELY 76.4 NM 
SOUTH-SOUTHEAST OF YAP. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 
262140Z SSMIS 91 GHZ MICROWAVE IMAGE DEPICT A BROAD, DEVELOPING LOW-
LEVEL CIRCULATION (LLC) WITH FLARING CONVECTION THROUGHOUT THE 
SOUTHERN PERIPHERY. ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE 
CONDITIONS FOR DEVELOPMENT CHARACTERIZED BY LOW VERTICAL WINDS SHEAR 
(10-15 KTS), WARM (29-30 C) SEA SURFACE TEMPERATURES, AND WEAK 
POLEWARD UPPER-LEVEL OUTFLOW. GLOBAL MODELS AGREE ON THE CONTINUED 
DEVELOPMENT OF 99W OVER THE NEXT 24-48 HOURS WITH A NORTH-
NORTHWESTWARD TRACK. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 
18 TO 23 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 IS UPGRADED TO 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.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 1.B.(1) TO 
MEDIUM.//
