Medium。

   (1) AN AREA OF CONVECTION (INVEST 98W) HAS PERSISTED NEAR
17.5N 137.5E, APPROXIMATELY 484 NM WEST-NORTHWEST OF GUAM. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY AND A PARTIAL 140343Z AMSR2 89GHZ
MICROWAVE IMAGE DEPICT WEAK FORMATIVE BANDING WITH ASSOCIATED AREAS
OF DEEP CONVECTION IN THE SOUTHEAST QUADRANT OF A LOW LEVEL
CIRCULATION. ENVIRONMENTAL ANALYSIS INDICATES MARGINAL CONDITIONS
FOR DEVELOPMENT WITH GOOD EQUATORWARD OUTFLOW ALOFT AND WARM (30-
31C) SEA SURFACE TEMPERATURES, OFFSET BY MODERATE (15-20 KTS)
VERTICAL WIND SHEAR (VWS). GFS AND NAVGEM HAVE BEEN CONSISTENT WITH
FORMATION OF A TROPICAL CYCLONE NEAR THIS LOCATION FOR THE PAST FOUR
MODEL RUNS. NUMERICAL MODELS ARE IN GENERAL AGREEMENT THAT INVEST
98W WILL TRACK POLEWARD AS IT QUICKLY CONSOLIDATES AND INTENSIFIES
OVER THE NEXT 24-48 HOURS. IN THE UPPER LEVELS, OUTFLOW IS EXPECTED
TO GRADUALLY IMPROVE WITH DECREASING VWS OVER THE NEXT 1 TO 2 DAYS
DUE TO A FAVORABLE CONFIGURATION OF AN UPPER LOW OVER WESTERN JAPAN
AND THE TUTT TO THE NORTHEAST. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 13 TO 18 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 IS MEDIUM.

JTWC發布TCFA

WTPN21 PGTW 152030
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT (INVEST 98W)//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
140 NM EITHER SIDE OF A LINE FROM 17.4N 132.2E TO 21.5N 131.3E
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 15 TO 20 KNOTS. METSAT
IMAGERY AT 151800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 17.4N 132.2E. THE SYSTEM IS MOVING WEST-NORTHWESTWARD AT 08
KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 98W) PREVIOUSLY LOCATED
NEAR 17.5N 137.5E IS NOW LOCATED NEAR 17.4N 132.2E, APPROXIMATELY
593 NM SOUTH-SOUTHEAST OF KADENA, OKINAWA, JAPAN. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY (MSI), A 151639Z AMSR2 36GHZ, AND AN
ASMR2 89GHZ MICROWAVE IMAGE DEPICT A BROAD ASYMMETRICAL CONVECTIVE
ZONE ON THE EASTERN BOUNDARY OF THE LOW LEVEL CIRCULATION (LLC).
DESPITE THE ASYMMETRICAL CONVECTIVE ZONE, 98W WILL CONSOLIDATE AND
INTENSIFY. ENVIRONMENTAL ANALYSIS INDICATES FAVORABLE CONDITIONS FOR
DEVELOPMENT WITH GOOD OUTFLOW ALOFT, WARM (30-31C) SEA SURFACE
TEMPERATURES, AND LOW (05-10 KTS) VERTICAL WIND SHEAR (VWS). IN THE
UPPER LEVELS, THE PATTERN IS COMPLEX WITH MULTIPLE STEERING FORCES;
THE FAVORABLE POLEWARD POSITIONING OF AN UPPER LEVEL LOW WILL
ENHANCE OUTFLOW AND DIVERGENCE ALOFT, WHILE IN THE LOWER LEVELS A
STRONG WESTERLY COMPONENT WILL ENHANCE CONSOLIDATION. HOWEVER, THERE
IS A STRONG DISPARITY AMONGST THE NUMERICAL MODELS OVER THE TRACK
AND INTENSIFICATION TIMELINE. GLOBAL AND ENSEMBLE GFS HAS 98W
INTENSIFYING WITHIN 18-36 HOURS AND TRACKING WEST-NORTHWEST AT A
HIGHER SPEED OF ADVANCE TO THE RYUKYU ISLANDS, WHILE GLOBAL AND
ENSEMBLE ECMWF HAVE A GRADUAL INTENSIFICATION PATTERN WITH A SLOWER
SPEED OF ADVANCE TO KYUSHU, JAPAN. CURRENT ANALYSIS INDICATES THAT
ECMWF HAS BEEN THE MORE CONSISTENT MODEL AT HANDLING THE
COMPLEXITIES OF 98W OVER THE LAST 48 HOURS. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 15 TO 20 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 HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
162030Z.
