菲律宾以东海面热带扰动96W,此前已3次被JTWC发布TCFA,也被3次取消TCFA。目前系统具备季风低压性质,尺度庞大,气压较低,外围风力较中心附近最大风力要强。
      
JMA于2014年7月29日凌晨对此TD系统发出GW

目前,在我国台湾东南洋面上有一个热带低压活动,今天(29日)下午5点钟其中心位于浙江省象山县东南方大约1500公里的西北太平洋洋面上,就是北纬18.6度、东经130.6度,中心附近最大风力有7级(15米/秒),中心最低气压为998百帕。

预计,该热带低压中心将以每小时15公里左右的速度向西北方向移动,强度逐渐加强,将于未来24小时内发展为台风(热带风暴级)。29日20时至30日20时,该低压对我国近海海域无影响。

96W.NAKRI.TCFA

WTPN21 PGTW 292300
MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//
SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
180 NM EITHER SIDE OF A LINE FROM 18.8N 131.1E TO 25.3N 126.8E
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 20 TO 25 KNOTS. METSAT
IMAGERY AT 292030Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 19.9N 130.5E. THE SYSTEM IS MOVING NORTH-NORTHWESTWARD AT 07
KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 18.9N
132.0E IS NOW LOCATED NEAR 19.9N 130.5E, APPROXIMATELY 416NM SOUTH-
SOUTHEAST OF KADENA AB, OKINAWA, JAPAN. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY DEPICTS A MONSOON DEPRESSION WITH IMPROVED DEEP
CONVECTION BEGINS TO CONSOLIDATE AS A TYPICAL TROPICAL CYCLONE. AN
OLDER ASCAT 291200Z ASCAT IMAGE DEPICTS AN EXTENSIVE REGION OF 30 TO
40 KNOT SOUTHWESTERLY WINDS OVER THE SOUTHERN SEMI-CIRCLE WITH 20 TO
25 KNOT WINDS OVER THE NORTHEAST QUADRANT. THE TOTAL PRECIPITABLE
WATER IMAGERY SHOWS A LARGE (ALMOST 700 NM IN DIAMETER), FAIRLY
SYMMETRIC ENVELOPE OF DEEP MOISTURE. UPPER-LEVEL ANALYSIS INDICATES
THE SYSTEM IS LOCATED IN AN AREA OF LOW TO MODERATE VERTICAL WIND
SHEAR AND EXCELLENT EQUATORWARD OUTFLOW. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 996 MB. DUE TO IMPROVED DEEP
CONVECTION AND CONSOLIDATION, 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
302300Z.

1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN

ISSUANCE OF NUMBERED TROPICAL CYCLONE WARNINGS AT THIS TIME. WINDS
IN THE AREA ARE ESTIMATED TO BE 20 TO 25 KNOTS. METSAT IMAGERY AT
302032Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 24.7N
128.0E. THE SYSTEM IS MOVING NORTHWESTWARD AT 09 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 19.9N
130.5E IS NOW LOCATED NEAR 24.7N 128.0E, APPROXIMATELY 100 NM SOUTH
OF KADENA AB, OKINAWA, JAPAN. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY SHOWS A SLOWLY CONSOLIDATING MONSOON DEPRESSION. THE
STRONGEST WINDS CONTINUE TO BE LOCATED ALONG THE EXTENDED PERIPHERY
OF THE SYSTEM, HOWEVER, CENTRAL WINDS REMAIN BETWEEN 15 TO 20 KNOTS.
AN OLDER ASCAT PASS AT 301237Z MISSED THE CENTRAL CORE OF THE
DEPRESSION, BUT ALONG THE WESTERN PERIPHERY THE WIND SPEEDS AGREE
WITH THE CURRENT ASSESSMENT. UPPER LEVEL ANALYSIS INDICATES A POINT
SOURCE ANTICYCLONE IS DEVELOPING OVER THE LOW LEVEL CIRCULATION
CENTER AND IS CREATING A LOW VERTICAL WIND SHEAR ENVIRONMENT.  
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 992 MB. BASED ON
A SLOW CONSOLIDATION OF THE STRONGER PERIPHERY WINDS TOWARD THE
CENTER BUT A LACK DEEP CENTRAL CONVECTION, THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS REMAINS HIGH. THIS SUPERSEDES REF A.
