SUBJ/TROPICAL CYCLONE FORMATION ALERT (INVEST 93C) CORRECTED//
REF/A/JOINT TYPHOON WRNCEN PEARL HARBOR HI/110154ZAUG2026//
AMPN/REF A IS TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
130 NM EITHER SIDE OF A LINE FROM 14.9N 137.4W TO 18.4N 142.4W
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 22 TO 28 KNOTS. METSAT
IMAGERY AT 111800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 15.0N 137.5W. THE SYSTEM IS MOVING NORTHWESTWARD AT 01
KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 93C) PREVIOUSLY LOCATED 10.4N 
140.7W IS NOW LOCATED 15.0N 137.5W, APPROXIMATELY 1044NM EAST-SOUTHEAST 
OF HILO, HAWAII. ANIMATED ENHANCED MULTISPECTRAL IMAGERY (MSI) DEPICTS A 
PARTIALLY EXPOSED, COMPACT LOW LEVEL CIRCULATION CENTER (LLCC) EMBEDDED 
WITHIN THE NORTHEASTERN CUSP OF A MUCH LARGER, ELONGATED TROUGH AXIS, 
WITH FLARING CONVECTION TO THE EAST. A 111519Z SSMIS 91H IMAGE SHOWED 
DISORGANIZED RAIN BANDS ALONG THE SOUTHERN PERIPHERY OF THE BROADER 
TROUGHING REGION, WITH A MORE CIRCULAR REGION OF DEEP CONVECTION NORTH 
OF THE EMBEDDED LLCC AT THE TIME OF THE IMAGE, WHICH HAS SINCE BEEN 
SHEARED TOWARD THE EAST. ENVIRONMENTAL ANALYSIS FOR THE AREA INDICATES A 
FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH LOW VERTICAL WIND SHEAR (10-
15 KTS), WARM SEA SURFACE TEMPERATURES (29-30 C), AND GOOD EQUATORWARD 
OUTFLOW ALOFT. GLOBAL MODELS GENERALLY AGREE THAT THE SYSTEM WILL 
CONSOLIDATE AND BECOME MORE SYMMETRIC WITH A STRENGTHENING WIND FIELD 
OVER THE NEXT 24-30 HOURS WHILE TRACKING GENERALLY WEST-NORTHWESTWARD.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 22 TO 28 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS REMAINS HIGH. THIS SUPERSEDES REF A (WTPN22 
PGTW 110200).
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY 
122100Z.
4. JUSTIFICATION FOR CORRECTION: CORRECTED MINIMUM SEA LEVEL PRESSURE IN 
PARAGRAPH 2 FROM 1001 MB TO 1006 MB.//
