型態乍看之下還不錯～
位於在大低壓帶的東側
走到西太副高西側了
要準備北轉囉～

JTWC 06Z維持評級LOW B. TROPICAL DISTURBANCE SUMMARY:      (2) THE AREA OF CONVECTION (INVEST 99W) PREVIOUSLY LOCATED NEAR 25.8N 152.6E, IS NOW LOCATED NEAR 25.8N 152.6E, APPROXIMATELY 600 NM EAST OF IWO-TO, JAPAN. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS AN ELONGATED SYSTEM WITH ISOLATED DEEP CONVECTION ALONG THE NORTHEASTERN PERIPHERY. A 090011Z ASCAT PASS SHOWS AN OPEN WAVE WITH STRONG GRADIENT WINDS TO THE NORTH AND VERY WEAK WINDS TO THE SOUTH. A 090136Z GPM 89GHZ MICROWAVE IMAGE DEPICTS FRAGMENTED CONVECTION ALONG THE NORTHEASTERN SIDE OF AN ELONGATED SYSTEM. THE DISTURBANCE IS LOCATED IN A MARGINAL ENVIRONMENT WITHIN THE SUBSIDENT REGION OF A TUTT CELL TO THE NORTHWEST, WITH MODERATE (15- 20 KNOT) VERTICAL WIND SHEAR. DYNAMICAL GUIDANCE IS MIXED WITH SOME MODELS SHOWING WEAK DEVELOPMENT OVER THEN NEXT 24-36 HOURS AS THE DISTURBANCE TRACKS NORTH-NORTHWEST, HOWEVER, THE WINDOW FOR THIS DEVELOPMENT IS VERY SHORT DUE TO STRONG WESTERLIES TO THE NORTH. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1010 MB. DUE TO THE DISORGANIZED LLCC AND MODERATE ENVIRONMENT, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

JTWC 00Z評價30節，並升格為熱帶低壓，但不上望TS強度。




中心南側掃出不錯的風力


JMA 00Z持續判定為溫帶氣旋。
