93W緯度太高了, 海水溫度較低, 加上輻合、輻散、風切都不利發展, 根本就沒有可能像12W一樣可以增強
從衛星雲圖亦可見, 雲團轉薄及被切往東面
不過JMA仍維持TD

LOW是發展機率10-30，很多擾動都一下就評LOW，所以因該不會太快吧!!
-------------------------------------------------回主題囉!!:)
日本氣象廳已於今天凌晨兩點升格為熱帶性低氣壓，而老J也於今天評等為LOW(代表發展機率10-30)
，台灣中央氣象局也在今日早上八點升格為熱低壓，氣壓1006百帕，沒有發展為輕度颱風之趨勢，而
日本氣象廳三日預報路徑則是以東北東進行!!
-------------------------------------------------有誰知道嗎??
中央氣象局於今天天氣圖，在92W和93W熱低壓上面畫個點點的圓圈圈，請問那是什意思??是有機會
變颱風嗎??還是
-------------------------------------------------已經沒LOW囉
標題可以改一下了，LOW已經被取消了!!

JTWC竟然這麼快就評級LOW!

AN AREA OF CONVECTION HAS PERSISTED NEAR 27.5N 152.3E,
APPROXIMATELY 540 NM EAST OF CHICHIJIMA, JAPAN. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY (MSI) AND A 081937Z SSMIS 37 GHZ
IMAGE INDICATE A PARTIALLY-EXPOSED LOW-LEVEL CIRCULATION CENTER
(LLCC) POSITIONED ON THE TAIL-END OF A COLD FRONT WITH DEEP
CONVECTION DISPLACED EAST OF THE CENTER. MSI ALSO DEPICTS COOLER,
DRIER AIR OVER THE NORTHERN AND WESTERN PERIPHERY, HOWEVER, THE
TOTAL PRECIPITABLE WATER PRODUCT INDICATES A SMALL SYSTEM WITH A
COCOON OF DEEP MOISTURE. A 081131Z ASCAT IMAGE AS WELL AS THE RECENT
CIMSS 850MB VORTICITY PRODUCT SHOWS A DEFINED BUT ELONGATED LLCC.
OVERALL, THE ENVIRONMENT IS UNFAVORABLE FOR SIGNIFICANT DEVELOPMENT
DUE TO MODERATE NORTHWESTERLY VERTICAL WIND SHEAR (20 KNOTS) AND THE
PROXIMITY TO MIDLATITUDE WESTERLY FLOW TO THE NORTH AND THE
BAROCLINIC ZONE. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 12
TO 18 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.
