WTPN21 PGTW 100730
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
150 NM EITHER SIDE OF A LINE FROM 9.5N 152.7E TO 12.9N 146.7E
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 20 TO 25 KNOTS. METSAT
IMAGERY AT 100700Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 9.9N 151.7E. THE SYSTEM IS MOVING NORTHWESTWARD AT 08 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 9.8N
152.4E, IS NOW LOCATED NEAR 9.9N 151.7E, APPROXIMATELY 455 NM EAST-
SOUTHEAST OF ANDERSEN AB, GUAM. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS A COMPACT SYSTEM OBSCURING A CONSOLIDATING LOW-LEVEL
CIRCULATION CENTER (LLCC). A 100608Z SSMIS MICROWAVE IMAGE REVEALS
THE BULK OF THE DEEP CONVECTION OVER THE WESTERN SEMI-CIRCLE WITH
FORMATIVE BANDS WRAPPING INTO THE LLCC. AN OLDER 092308Z ASCAT PASS
SHOWED A WELL-DEFINED 10 TO 15 KNOT CIRCULATION AND ISOLATED 20 TO
25 KNOT WIND BARBS OVER THE NORTHERN QUADRANTS. UPPER-LEVEL ANALYSIS
INDICATES A FAVORABLE ENVIRONMENT WITH DUAL OUTFLOW, ONE ENHANCED BY
A TUTT CELL TO THE NORTHEAST AND A WESTWARD OUTFLOW ENHANCED BY THE
STRONG EASTERLY WINDS ALONG THE SOUTHERN PERIPHERY OF THE RIDGE TO
THE NORTH. NUMERIC WEATHER PREDICTION MODELS DEVELOP THIS
DISTURBANCE IN VARYING DEGREES WITH THE MOST AGGRESSIVE BEING GFS.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. DUE TO
PERSISTENT CONVECTION, IMPROVING ORGANZIATION AND FAVORABLE
CONDITIONS, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
110730Z.
