JTWC:MEDIUM
(1) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED
NEAR 17.0N 138.7E, IS NOW LOCATED NEAR 15.6N 138.4E, APPROXIMATELY
390 NM WEST-NORTHWEST OF GUAM. RECENT ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY AND RECENT MICROWAVE PASSES DEPICT LOW AND MID-
LEVEL CYCLONIC TURNING BEGINNING TO CONSOLIDATE WITH INCREASED
CONVECTION ASSOCIATED WITH A SYMMETRIC LOW LEVEL CIRCULATION CENTER,
EVIDENT ON A 111346Z RSCAT PASS. THE OVERALL ENVIRONMENT IS
MARGINALLY-FAVORABLE WITH GOOD DIVERGENCE ALOFT ASSOCIATED WITH A
POINT SOURCE FIVE DEGREES WEST OF THE LLCC SUSTAINING THE CURRENT
CONVECTION, LIGHT TO MODERATE (10 TO 15 KNOT) VERTICAL WIND SHEAR,
VERY WARM SEA SURFACE TEMPERATURES, AND HIGH OHC CONTENT. GLOBAL
MODELS SHOW DEVELOPMENT OF THIS DISTURBANCE AS IT TRACKS EASTWARD
NEAR THE MARIANAS THEN POLEWARD. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1005 MB. GIVEN THE IMPROVED ENVIRONMENTAL
CONDITIONS, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.

1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
140 NM EITHER SIDE OF A LINE FROM 15.4N 138.1E TO 17.9N 141.0E
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 111800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 15.5N 138.6E. THE SYSTEM IS MOVING SOUTHEASTWARD AT 05
KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED
NEAR 15.8N 138.2E, IS NOW LOCATED NEAR 15.5N 138.6E, APPROXIMATELY
375NM WEST-NORTHWEST OF GUAM. RECENT ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY AND A 111914Z SSMIS 91GHZ MICROWAVE PASS DEPICT
CONSOLIDATED LOW AND MID-LEVEL CYCLONIC TURNING, DECREASED YET
FRAGMENTED DEEP CONVECTION IN LIEU OF DIURNAL MAXIMUMS AROUND THE
LOW LEVEL CIRCULATION CENTER (LLCC), EVIDENT ON A 111346Z RSCAT
PASS. THE OVERALL ENVIRONMENT IS FAVORABLE WITH EXCELLENT DIVERGENCE
ALOFT, LIGHT TO MODERATE VERTICAL WIND SHEAR (10 TO 15 KNOTS), VERY
WARM SEA SURFACE TEMPERATURES, AND HIGH OHC CONTENT. GLOBAL DYNAMIC
MODEL GUIDANCE CONFIRMS EXPECTED DEVELOPMENT AND INTENSIFICATION OF
THIS SYSTEM AS IT TRACKS EAST AND NORTHEASTWARD JUST WEST THE
MARIANAS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1003 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS HIGH.

熱帶性低氣壓９３Ｗ目前位於關島西方海域，
過去中心近似滯留，系統環流雖然相當廣泛，
但環流結構鬆散，型態稍差，仍需近一步整合。
至於未來移動方向，以目前資料研判，
短期內將沿著高壓邊緣朝東北移動，
後期是繼續北上還是西折，
這部分取決於高壓強弱及整個大低壓帶的發展，
變數非常高，仍有待觀察。

ＥＣ　００Ｚ
誤差圈很大
信心度極低

小多啦

這是小程式今晚模擬的結果
預測93W巔峰強度可達100KTS (一分鐘平均)
前提是最後走西進路線 如果北轉大概只有65KTS的強度
每個Model詳細的路徑及強度預測如最下面的附件(TXT文字檔)
