JTWC 31/03Z評級Low。

(2) AN AREA OF CONVECTION (INVEST 92W) HAS PERSISTED NEAR
16.8N 131.0E, APPROXIMATELY 590 NM EAST-NORTHEAST OF MANILA,
PHILIPPINES. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS
A FULLY EXPOSED LOW LEVEL CIRCULATION FLANKED BY SPARSE CONVECTION
OVER THE EASTERN SEMICIRCLE. THE ENVIRONMENT IS MARGINALLY FAVORABLE
FOR DEVELOPMENT WITH LOW (5-10 KTS) VERTICAL WIND SHEAR AND WARM (29-
30 CELSIUS) SEA SURFACE TEMPERATURES OFFSET BY CONVERGENT FLOW
ALOFT. NUMERICAL MODELS ARE IN GOOD AGREEMENT THAT THE SYSTEM WILL
CONTINUE TO CONSOLIDATE AND IT TRACKS NORTHWESTWARD TOWARDS TAIWAN
OVER THE NEXT 24 HOURS.  MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 10 TO 15 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 LOW.

JTWC06Z評級提升為Medium

(2) AN AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED NEAR
16.8N 131.0E IS NOW LOCATED NEAR 17.1N 129.9E, APPROXIMATELY 535 NM
EAST-NORTHEAST OF MANILA, PHILIPPINES. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY (MSI) AND A 310457Z AMSR2 89GHZ MICROWAVE IMAGE
DEPICT A PARTIALLY EXPOSED LOW LEVEL CIRCULATION WITH CONVECTIVE
BANDING DEVELOPING ALONG THE EASTERN PERIPHERY. THE ENVIRONMENT IS
MARGINALLY FAVORABLE FOR DEVELOPMENT WITH LOW (5-10 KTS) VERTICAL
WIND SHEAR AND WARM (29-30 CELSIUS) SEA SURFACE TEMPERATURES, OFFSET
BY UNFAVORABLE CYCLONIC FLOW OVER THE WESTERN PORTION OF THE LLC.
NUMERICAL MODELS ARE IN GOOD AGREEMENT THAT THE SYSTEM WILL CONTINUE
TO CONSOLIDATE AND IT TRACKS NORTHWESTWARD TOWARDS TAIWAN OVER THE
NEXT 24 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10
TO 15 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 UPGRADED TO MEDIUM.

高海溫但風切也強
成颱不易
不過熱帶低壓應該沒什麼問題

JTWC 31/2130Z發布TCFA。

WTPN22 PGTW 312130
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT (INVEST 92W)//
REF/A/JOINT TYPHOON WRNCEN PEARL HARBOR HI/311821Z JUL 20//
AMPN/REF A IS TROPICAL CYCLONE FORMATION ALERT (WTPN21 PGTW 311830)//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
120 NM EITHER SIDE OF A LINE FROM 18.1N 130.0E TO 22.7N 125.4E
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 311800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 18.4N 129.6E. THE SYSTEM IS MOVING NORTHWARD AT 08 KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED
NEAR 17.6N 129.6E IS NOW LOCATED NEAR 18.4N 129.6E, APPROXIMATELY
465 NM SOUTHEAST OF ISHIGAKIJIMA. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY DEPICTS A TIGHT LOW LEVEL CIRCULATION (LLC) WITH
PERSISTENT DEEP CONVECTION OVERHEAD POTENTIAL FORMATIVE BANDING
BEGINNING TO WRAP IN FROM THE EAST. A 311709Z AMSR2 GW1 89GHZ
MICROWAVE IMAGE SHOWS FRAGMENTED FORMATIVE BANDING WRAPPING IN FROM
THE EAST AND SOUTH. A 311300Z METOP-B ASCAT PASS REVEALS TIGHT
TROUGHING WITH A SWATH OF 25 TO 30 KNOT WINDS ON THE EASTERN SIDE.
92W IS CURRENTLY IN A FAVORABLE ENVIRONMENT WITH GOOD EQUATORWARD
OUTFLOW, LOW (5 TO 10 KNOTS) VERTICAL WIND SHEAR, AND WARM (30
CELSIUS) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN GOOD
AGREEMENT THAT 92W WILL TRACK GENERALLY NORTHWESTWARD WHILE
INTENSIFYING, POTENTIALLY REACHING WARNING THRESHOLD WITHIN 36
HOURS. 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
012130Z.
