: MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
: SUBJ/TROPICAL CYCLONE FORMATION ALERT//
: RMKS/
: 1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
: 235 NM EITHER SIDE OF A LINE FROM 9.0N 142.7E TO 12.6N 134.2E
: 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 18 TO 20 KNOTS. METSAT
: IMAGERY AT 101630Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
: NEAR 9.6N 142.6E. THE SYSTEM IS MOVING WEST-NORTHWESTWARD AT 16
: KNOTS.
: 2. REMARKS: AN AREA OF CONVECTION PREVIOUSLY LOCATED 9.0N
: 144.0E IS NOW LOCATED NEAR 9.6N 142.6E, APPROXIMATELY 260 NM EAST OF
: YAP. RECENT ENHANCED INFRARED SATELLITE IMAGERY DEPICTS A
: CONSOLIDATING LOW-LEVEL CIRCULATION CENTER WITH VIGOROUS CONVECTION
: ALONG THE WESTERN PERIPHERY. A 101210Z AMSU-B IMAGE DEPICTS
: FORMATIVE CONVECTIVE BANDING ALONG THE NORTHERN AND WESTERN
: PERIPHERY OF THE SYSTEM, SHOWING SOME CONSOLIDATION COMPARED TO 12
: HOURS AGO. LOCAL OBSERVATIONS FROM YAP INDICATE A DROP IN PRESSURE
: OF 02 MB OVER THE PAST 24 HOURS. UPPER LEVEL ANALYSIS INDICATES SOME
: EQUATORWARD OUTFLOW AND VARYING LEVELS OF VERTICAL WIND SHEAR, LOW
: SHEAR OVER THE NORTHERN PORTION AND HIGH (20 TO 30 KTS) IN THE
: SOUTHERN PORTION OF THE AREA. MODELS ARE IN GOOD AGREEMENT THAT THE
: SYSTEM WILL CONTINUE TO TRACK TO THE WEST-NORTHWEST UNDER THE
: STEERING INFLUENCE OF THE SUBTROPICAL RIDGE POSITIONED TO THE
: NORTHEAST. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 20
: KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB.
: DUE TO INCREASED CONSOLIDATION OF THE LLCC, THE POTENTIAL FOR
: 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
: 111700Z.//
: NNNN
: 娜克莉之後老J就變得很積極啊~
: 94W預報有略為北調並調強強度的趨勢，但應該不至於登陸台灣。
