SUBJ/TROPICAL CYCLONE FORMATION ALERT//
REF/A/JOINT TYPHOON WRNCEN PERAL HARBOR HI/260651ZJUL2026//
AMPN/REF A IS A TROPICAL CYCLONE FORMATION ALERT.//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
120 NM EITHER SIDE OF A LINE FROM 12.4N 178.3W TO 13.8N 174.3E
WITHIN THE NEXT 12 TO 24 HOURS. AVAILABLE DATA DOES NOT JUSTIFY
ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME.
WINDS IN THE AREA ARE ESTIMATED TO BE 23 TO 28 KNOTS. METSAT
IMAGERY AT 261200Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 12.7N 179.8E. THE SYSTEM IS MOVING WESTWARD AT 13 KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 92C), PREVIOUSLY LOCATED 
NEAR 12.7N 177.5W IS NOW LOCATED NEAR 12.7N 179.8E, APPROXIMATELY 
597NM NORTHEAST OF MAJURO. ANIMATED ENHANCED INFRARED SATELLITE 
IMAGERY (EIR) DEPICTS AN AREA OF CONSOLIDATING DEEP CONVECTION IN THE 
NORTHERN AND EASTERN PERIPHERIES, WITH CURVED FLARING CONVECTIVE BANDS 
TO THE WEST-NORTHWEST OF THE LOW-LEVEL CIRCULATION CENTER (LLCC). THE 
STRONGEST WINDS ARE PRIMARILY CONFINED TO THE NORTHERN SEMICIRCLE WITH 
RELATIVELY WEAKER WINDS TO THE SOUTH. ENVIRONMENTAL ANALYSIS REVEALS 
FAVORABLE CONDITIONS FOR DEVELOPMENT WITH LOW VERTICAL WIND SHEAR (15 
KNOTS OR LESS), STRONG UPPER-LEVEL OUTFLOW ALOFT, AND WARM (28-29C) 
SEA SURFACE TEMPERATURES. GLOBAL MODELS DEPICT 92C CONTINUING TO 
CONSOLIDATE OVER THE NEXT 12-24 HOURS WITH GUIDANCE SHOWING A 
GENERALLY WESTWARD TRACK. CURRENT WIND SPEEDS ARE LISTED AT 25 KNOTS 
WITH THE SYSTEM BEGINNING TO MOVE OVER A MORE CONDUCIVE ENVIRONMENT 
FOR TROPICAL CYCLONE DEVELOPMENT. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 23 TO 28 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED 
TO BE NEAR 1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT 
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS HIGH. THIS 
SUPERSEDES REF A (WTPN22 PHNC 260700).
