GFS看好發展，未來不排除從台灣東南方海域北上
不過時間還久，再觀察幾天吧XD

GFS最新報跟前一報差不多

目前時間還久，發展及近台程度很可觀...

JTWC評級Low

B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 92W) HAS PERSISTED NEAR 3.0N
150.0E, APPROXIMATELY 285 NM SOUTH-SOUTHWEST OF CHUUK. ANIMATED
INFRARED DVORAK SATELLITE IMAGERY DEPICTS DEEP CONVECTION FLARING TO
THE WEST OF A DEVELOPING LOW LEVEL CIRCULATION CENTER EVIDENT IN A
091512Z AMSR2 89 GHZ MICROWAVE IMAGE. THE AMSR2 IMAGE ALSO REVEALS
WEAK CONVECTIVE BANDING WRAPPING INTO THE CIRCULATION FROM ALL
QUADRANTS. ENVIRONMENTAL CONDITIONS ARE FAVORABLE, WITH MODERATE
UPPER-LEVEL DIFFLUENCE, LOW VERTICAL WIND SHEAR (10-15 KTS)
AND HIGH SEA SURFACE TEMPERATURES (30-32C). GLOBAL MODELS DEPICT
GRADUAL CONSOLIDATION OF THIS DISTURBANCE AS IT TRACKS WEST-
NORTHWESTWARD OVER THE NEXT FEW DAYS. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. BECAUSE THIS CIRCULATION
IS JUST BEGINNING TO CONSOLIDATE, THE POTENTIAL FOR THE DEVELOPMENT
OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

(1) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED
NEAR 3.0N 150.0E, IS NOW LOCATED NEAR 3.3N 149.5E, APPROXIMATELY
282 NM SOUTH-SOUTHWEST OF CHUK. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY AND A 092236Z GPM 89 GHZ IMAGE DEPICT FLARING DEEP
CONVECTION WITH FORMATIVE BANDING WRAPPING INTO A DEVELOPING A LOW
LEVER CIRCULATION CENTER(LLCC). ENVIRONMENTAL CONDITIONS SHOW
IMPROVED UPPER LEVEL OUTFLOW AND LIGHT TO MODERATE (15-20 KNOTS)
VERTICAL WIND SHEAR, AND HIGH (29-30C) SEA SURFACE TEMPERATURES. A
100010Z PARTIAL ASCAT PASS SHOWS WINDS OF 15-20 KNOTS ALONG THE
NORTHERN PERIPHERY OF THE LLCC. THE GLOBAL MODELS SHOW SLOW
DEVELOPMENT OF THE SYSTEM AS IT TRACKS TO THE NORTHWEST OVER THE
NEXT FEW DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15
TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR
1005 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.

結構鬆鬆散散

低層環流螺旋性有了
但還缺乏深層對流進一步鞏固




目前預報路徑往西修正
通過菲律賓呂宋島後北轉
只是對強度的看法就不太一致了～

THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED
NEAR 3.0N 150.0E, IS NOW LOCATED NEAR 4.0N 141.7E, APPROXIMATELY 145
NM NORTH OF YAP. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND AN
110034Z MHS METOP-A 89GHZ MICROWAVE PASS DEPICT SHALLOW CONVECTION
ALONG THE WESTERN SEMI-CIRCLE OF A LOW LEVEL CIRCULATION CENTER
(LLCC). AS THE LLCC MOVED WESTWARD FROM UNDERNEATH A POINT SOURCE,
ENVIRONMENTAL ANALYSIS SHOWS MARGINALLY FAVORABLE CONDITIONS WITH
LOW (10-15 KNOTS) VERTICAL WIND SHEAR, DIFFLUENT OUTFLOW, AND
CONDUCIVE (29-30C) SEA SURFACE TEMPERATURES. AN 110036Z METOP-A 25KM
ASCAT PASS SHOWS 15-20 KNOT WINDS ALONG THE NORTHERN PERIPHERY OF
THE LLCC. DYNAMIC GLOBAL MODELS SHOW SLOW DEVELOPMENT OF THE SYSTEM
AS IT TRACKS TO THE NORTHWEST OVER THE COMING DAYS. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. BASED ON THE
MARGINALLY FAVORABLE ENVIRONMENT ANALYZED, ALBEIT, THE SUBSIDED DEEP
CONVECTION, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS MEDIUM.
