REF/A/MSG/JOINT TYPHOON WRNCEN PEARL HARBOR HI/220851ZAUG2018//
AMPN/REFS A IS A TROPICAL CYCLONE FORMATION ALERT.//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
120 NM EITHER SIDE OF A LINE FROM 23.2N 120.9E TO 26.3N 120.4E
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 230800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 23.5N 121.1E. THE SYSTEM IS MOVING NORTH-NORTHEASTWARD AT 08
KNOTS.
2. REMARKS: THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED
NEAR 22.8N 120.6E, IS NOW LOCATED NEAR 23.5N 121.1E, APPROXIMATELY
100 NM SOUTH-SOUTHWEST OF TAIPEI, TAIWAN. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY AND A 230136Z MHS 89GHZ MICROWAVE IMAGE SHOW AN
ELONGATED CIRCULATION WITH A PARTIALLY EXPOSED LOW LEVEL CIRCULATION
CENTER AND CONVECTION LOCATED TO THE SOUTH. A 221230Z PARTIAL ASCAT
PASS SHOWS A BROAD CIRCULATION WITH PRIMARILY 5-10 KNOTS NEAR THE
CENTER AND 15-25 KNOTS AROUND THE PERIPHERY. THE DISTURBANCE IS
CURRENTLY LOCATED OVER TAIWAN IN AN AREA OF EXCELLENT EQUATORWARD
OUTFLOW, LOW TO MODERATE VERTICAL WIND SHEAR (10-20 KNOTS), AND WARM
SEA SURFACE TEMPERATURES (28-30 CELSIUS) IN THE SURROUNDING WATERS.
GLOBAL MODELS DEPICT THE SYSTEM TRACKING NORTH BEFORE TURNING
WESTWARD WHILE INTENSIFYING SLIGHTLY. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 18 TO 23 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 HIGH. THIS
SUPERSEDES REF A (WTPN21 PGTW 220900).

cma 定位有点问题 应该要东北调一点 中心在嘉义附近 现在是在东北移动

目前来看福建中部的可能性大大概在福州一带

另外这货在借助台湾的地形在发展自己
涡度已经浑圆发白了
