JTWC 06z評級Low
(1) AN AREA OF CONVECTION (INVEST 93W) HAS PERSISTED NEAR 3.0N
155.9E, APPROXIMATELY 914 NM SOUTHEAST OF GUAM. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY SHOWS DISORGANIZED FLARING
CONVECTION AND BROAD CYCLONIC TURNING. A 060440Z SSMI 85 GHZ
MICROWAVE IMAGE REVEALS LIMITED DEEP CONVECTION AND NO LOWER LEVEL
STRUCTURE IS INDICATED. A 052223Z ASCAT PASS RETURNED MOSTLY 10 KNOT
WINDS, WITH AN AREA OF 15 KNOT WINDS TO THE NORTH. UPPER LEVEL
ANALYSIS SHOWS WEAK, WIDESPREAD DIVERGENCE ALOFT IN THE AREAS OF
FLARING CONVECTION AND LOW (10-15 KT) VERTICAL WIND SHEAR. SEA
SURFACE TEMPERATURES ARE FAVORABLE, 28-29 DEGREES CELSIUS. NAVGEM
AND GFS PREDICT 93W WILL MOVE TO THE NORTHWEST AND STRENGTHEN IN THE
LATER TAUS, WHILE UKMET AND ECMWF MAINTAIN THE CIRCULATION TO THE
PHILIPPINES BUT DO NOT INTENSIFY THE DISTURBANCE. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1010 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW.

評級已提升至Medium
B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED
NEAR 3.0N 155.9E, IS NOW LOCATED NEAR 8.7N 150.7E, APPROXIMATELY 447
NM SOUTHEAST OF GUAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A
062042Z SSMIS 91 GHZ IMAGE SHOWS A CONSOLIDATING LOW LEVEL
CIRCULATION CENTER (LLCC) WITH FORMATIVE BANDING AND FLARING
CONVECTION. UPPER LEVEL ANALYSIS SHOWS THAT THE DISTURBANCE IS
LOCATED IN AN AREA OF MODERATE (15-20 KNOT) VERTICAL WIND SHEAR
(VWS) WITH STRONG POLEWARD OUTFLOW. A RECENT ASCAT PASS SHOWS AN
AREA OF 15-20 KNOT WINDS LOCATED IN THE NORTHERN PERIPHERY. WARM SEA
SURFACE TEMPERATURES (28-29 CELSIUS) WILL CONTINUE TO SUPPORT
ADDITIONAL DEVELOPEMET OF 93W. GLOBAL MODELS ARE IN GOOD AGREEMENT
THAT 93W WILL TRACK TO THE WEST, BUT VARY ON THE SPEED AND RATE OF
INTENSIFICATION. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15
TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1009
MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL
CYCLONE WITHIN THE NEXT 24 HOURS REMAINS MEDIUM.

JTWC 18Z發佈"TCFA",逐漸西移。
WTPN21 PGTW 072230
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
200 NM EITHER SIDE OF A LINE FROM 7.4N 151.6E TO 10.1N 144.8E
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 072100Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 7.5N 151.1E. THE SYSTEM IS MOVING WESTWARD AT 08 KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED
NEAR 9.0N 149.2E, IS NOW LOCATED NEAR 7.5N 151.1E, APPROXIMATELY 520
NM SOUTHEAST OF ANDERSEN AFB, GUAM. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS A CONSOLIDATING LOW LEVEL CIRCULATION CENTER (LLCC)
COVERED BY CONVECTION THAT IS BEGINNING TO PERSIST AND WRAP IN. A
072001Z SSMIS 91GHZ MICROWAVE IMAGE REVEALS FORMATIVE LOW LEVEL
BANDING WRAPPING INTO THE LLCC WITH POCKETS OF DEEP CONVECTION IN
THE VICINITY OF THE LLCC. A 071043Z ASCAT IMAGE SHOWS A BROAD
CIRCULATION WITH PRIMARILY 10-15 KNOT WINDS AND HIGHER WINDS
LOCATED TO THE NORTH OF THE DISTURBANCE, BEGINNING TO WRAP IN. UPPER
LEVEL ANALYSIS SHOWS THAT 93W IS LOCATED IN AN AREA OF STRONG
POLEWARD OUTFLOW, MODERATE (15-20 KNOT) VERTICAL WIND SHEAR (VWS),
AND WARM SEA SURFACE TEMPERATURES (29-31 CELSIUS) WHICH WILL
CONTINUE TO SUPPORT ADDITIONAL DEVELOPMENT OF THE DISTURBANCE.
GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 93W WILL TRACK TO THE WEST.
GFS AND NAVGEM PREDICT 93W WILL DEVELOP QUICKLY; HOWEVER, UKMET AND
ECMWF FAVOR ONLY SLIGHT INTENSIFICATION AS THE CIRCULATION
PROPAGATES WESTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE
NEAR 1007 MB. 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
082230Z.//

JTWC 18Z升格02W,中心風速只有20kts,大約還要再整合2天才會達TS。
