JTWC 20Z評級Low

  (1) AN AREA OF CONVECTION (INVEST 92W) HAS PERSISTED NEAR
22.0N 118.0E, APPROXIMATELY 262 NM SOUTHWEST OF TAIPEI. A RECENT
ASCAT METOP-A PASS DEPICTS A CLOSED, WELL-DEFINED LOW LEVEL
CIRCULATION WITH A LARGE SWATH OF 20 KNOT WINDS TO THE SOUTHERN
SECTOR. INFRARED IMAGERY SHOWS THE CIRCULATION AS FULLY EXPOSED WITH
SPARSE DEEP CONVECTION TO THE SOUTH. UPPER LEVEL ANALYSIS INDICATES
A MODERATE ENVIRONMENT WITH LOW VERTICAL WIND SHEAR (5-10KT), BUT
VERY LITTLE DIVERGENCE. SEA SURFACE TEMPERATURES ARE FAVORABLE AT 28-
30C. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT THE CIRCULATION WILL
GRADUALLY INTENSIFY AS IT MOVES NORTHEAST. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 997 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

92W已經有明確的旋轉趨勢

路徑預計從台灣上空路過

未來三天的天氣會變得更不穩定

【熱帶低壓，今夜穿越台灣】

朝台灣南部陸地接近中，

預計今天夜晚就會穿越，環流相當明顯，

不排除有更進一步增強的機會！

明天穿越之後，沿著東海岸北上，

移動速度慢，影響多日，

今天夜晚開始，四、五、六、日、一，

　

中、南、東下雨時間長，

加上強盛西南風，

可能出現明顯雨勢，

北部則是偶爾陣雨，以午後雷陣雨為主。

熱帶性低氣壓怎麼走很重要，

偏東一點，雲雨帶可能從海上通過，

偏西一點，雲雨帶直接蓋在台灣上空，

不可輕忽！

評級提升至Medium

(1) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED
NEAR 22.0N 118.0E, IS NOW LOCATED NEAR 22.4N 119.0E, APPROXIMATELY
203 NM SOUTHWEST OF TAIPEI. ANIMATED MULTISPECTRAL IMAGERY DEPICTS A
WELL-DEFINED LOW LEVEL CIRCULATION CENTER (LLCC) WITH FLARING
CONVECTION BEGINNING TO WRAP INTO THE LLCC. A 220157Z MHS METOP-A
IMAGE EMPHASIZES THAT THE CONVECTION IS BECOMING BETTER ORGANIZED
AND IS WRAPPING IN. THE ENVIRONMENT IS FAVORABLE FOR DEVELOPMENT
WITH LOW TO MODERATE VERTICAL WIND SHEAR (10-20 KTS), GOOD
DIVERGENCE ALOFT, AND WARM SURFACE TEMPERATURES OF 28-30C.
GLOBAL MODELS ARE IN GOOD AGREEMENT THAT THE CIRCULATION WILL
GRADUALLY INTENSIFY AS IT MOVES NORTH.  MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 997 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO
MEDIUM.
