ALMOST QUASI-STATIONARY BEFORE BEGINNING TO TRACK WESTWARD AND
GRADUALLY INTENSIFYING. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A

JTWC 13Z評級提升至"MEDIUM"。
(1) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED
NEAR 2.2N 166.4E, IS NOW LOCATED NEAR 3.4N 166.5E, APPROXIMATELY 237
NM EAST-SOUTHEAST OF KOSRAE. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY SHOWS A FLARING CONVECTION OBSCURING A CONSOLIDATING LOW
LEVEL CIRCULATION (LLC) WITH FORMATIVE BANDING BEGINNING TO WRAP IN.
A 170712Z WINDSAT 37GHZ SHOWS A LARGE AREA OF CONVECTION EXTENDING
NORTH FROM THE LLC WITH FORMATIVE MID-LEVEL BANDIND. A 171040Z METOP-
B ASCAT PASS SHOWS AN ELONGATED CIRCULATION WITH A SMALL SWATH OF 20
KNOT WIND BARBS TO THE NORTH OF THE LLC. 92W IS CURRENTLY IN A
FAVORABLE ENVIRONMENT WITH EXCELLENT WESTWARD OUTFLOW, LOW (10 TO 15
KNOT) VERTICAL WIND SHEAR, AND VERY WARM (29 TO 31 CELSIUS) SEA
SURFACE TEMPERATURES. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 92W
WILL TRACK WESTWARD WITH MINIMAL INTENSIFICATION BEFORE CURVING TO
THE NORTH AND BEGINNING QUICKER INTENSIFICATION. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 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 UPGRADED TO MEDIUM.

JTWC92W1712Z最新定位於
3.4°N 166.5°E
vis006-lalo.gif
風場圖顯示系統本身已有20KT左右的實力
79_104531_f93631f9c4b65e1.jpg
惟中心仍狹長,尚需一段時間整合發展


GFS雖然經常高估強度,但最近預測路徑能力表現不差,值得一看

整體螺旋性亦可從雲圖上見到有愈來愈佳的趨勢

92W目前正處於一個具有優良的雙流出通道、低垂直風切和暖海溫的良好環境中,後續發展情況有待繼續觀察。
WTPN21 PGTW 180300
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT (INVEST 92W)//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
165 NM EITHER SIDE OF A LINE FROM 3.5N 158.6E TO 6.1N 151.9E
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 23 KNOTS. METSAT
IMAGERY AT 190600Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 3.7N 158.2E. THE SYSTEM IS MOVING WEST-NORTHWESTWARD AT 08
KNOTS.
2. REMARKS:
THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED NEAR 3.4N
166.5E, IS NOW LOCATED NEAR 4.1N 164.4E, APPROXIMATELY 750 NM EAST-
SOUTHEAST OF CHUUK. ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS
FLARING CONVECTION SURROUNDING SEVERAL WEAK, LOW LEVEL CIRCULATION
CENTERS (LLCC) EMBEDDED WITHIN AN ELONGATED AREA OF LOW PRESSURE. A
172208Z MHS METOP-A 89GHZ IMAGE SHOWS A LARGE AREA OF SCATTERED,
DISORGANIZED CONVECTION WRAPPING INTO A VERY BROAD CIRCULATION
CENTER. 92W IS CURRENTLY IN A FAVORABLE ENVIRONMENT WITH EXCELLENT
DUAL OUTFLOW CHANNELS, LOW (5-10 KTS) VERTICAL WIND SHEAR, AND WARM
(28-29C) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN GOOD
AGREEMENT THAT 92W WILL TRACK WESTWARD BEFORE TURNING TO THE
NORTHWEST, AS IT FURTHER INTENSIFIES AND SUBSEQUENTLY REACHES
WARNING CRITERIA. HOWEVER, MODELS DIFFER ON THE EXACT TIMING OF THE
INTENSIFICATION WITH GFS, THE MOST AGGRESSIVE, SHOWING THE SYSTEM
REACHING WARNING STATUS WITHIN THE NEXT 18 HOURS. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 15 TO 20 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 HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
190300Z.//

未來路徑大致應該就是類似這樣的走法,剩下的就只是北轉時間早跟晚的問題了。  發表於 2019-2-18 14:25
未來應該是不會影響到我們這邊陸上的天氣,但東方海面如過它再靠近一些長浪跟大浪多少就能會發生。  發表於 2019-2-18 14:21
因為還很遠路徑變化還很大雖然不是一丁但還是有在西修一點點的可能性,所以它影響我們東方海面天氣的可能是會有的。  發表於 2019-2-18 14:18
以這個距離北轉對我們這邊而言是完全不受影響的,但如果它未來的路徑還有再稍為往西修正的話。  發表於 2019-2-18 14:15

目前的各數值路徑預測,一周內基本有共識,但EC部分系集與GFS在中長期預報中對於144~168+以後的中長期預測路徑西進或是北轉分歧不小

另由於環境良好,發展條件優異,數值系集均大多看好92W一兩天內發展為TS
