1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN 160 NM EITHER SIDE OF A LINE FROM 16.1N 139.6E TO 23.4N 134.3E WITHIN THE NEXT 06 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 17 TO 22 KNOTS. METSAT IMAGERY AT 081800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 17.2N 139.1E. THE SYSTEM IS MOVING NORTH-NORTHWESTWARD AT 09 KNOTS. 2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 16.6N 139.8E IS NOW LOCATED NEAR 17.2N 139.1E, APPROXIMATELY 405 NM WEST- NORTHWEST OF ANDERSEN AFB, GUAM. ANIMATED INFRARED SATELLITE IMAGERY DEPICTS A LARGE CLUSTER OF DEEP CONVECTION DISPLACED JUST NORTHWEST OF THE LOW-LEVEL CIRCULATION CENTER (LLCC). RECENT MICROWAVE IMAGERY INDICATES FORMATIVE BANDING EAST WRAPPING INTO THE NORTH QUADRANT. A 081128Z ASCAT PARTIAL IMAGE SHOWS 15-20 KNOT UNFLAGGED WINDS EAST AND NORTH OF A DEFINED CENTER; THERE ARE ALSO 20-25 KNOT WINDS NORTHEAST OF THE CENTER HOWEVER THEY ARE ADJACENT TO NUMEROUS RAIN- FLAGGED WINDS. OVERALL, THE UPPER-LEVEL ENVIRONMENT REMAINS MARGINAL WITH MODERATE TO STRONG SOUTHERLY VERTICAL WIND SHEAR (20-30 KNOTS) HAMPERING DEVELOPMENT. EQUATORWARD OUTFLOW IS POOR WITH FAIR POLEWARD OUTFLOW ENHANCED BY STRONG FLOW BETWEEN A TUTT CELL NEAR 25N 136E AND AN ANTICYCLONE NEAR 23N 149E. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 17 TO 22 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS HIGH. 3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY 092200Z.// NNNN 趕著出門不好意思指貼原文在關島附近的熱帶擾動92W被評級成HIGH 有機會於一天之內升格成熱帶氣旋(熱帶低壓) 未來趨勢往北北西前進似乎...不太有引響的樣子XD 應1F要球刪除推文 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 123.192.212.133
