1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 5.4N
148.6E, IS NOW LOCATED NEAR 6.0N 147.1E, APPROXIMATELY 475 NM SOUTH-
SOUTHEAST OF GUAM. ANIMATED MULTISPECTRAL AND INFRARED (IR)
SATELLITE IMAGERY SHOWS A LOW LEVEL CIRCULATION CENTER (LLCC) HAS
BEEN RAPIDLY CONSOLIDATING OVER THE PAST SIX HOURS, HOWEVER DEEP
CONVECTION HAS CONTINUED TO DECREASE AROUND THE WELL DEFINED LLCC.
RECENT AMSU-B CROSS SECTIONS INDICATE A WEAK WARM CORE SYSTEM IS
DEVELOPING. IN ADDITION, THE AMSU AND IR TRACK WINDS INDICATE
SURFACE WINDS ARE BETWEEN 15 TO 20 KNOTS. UPPER LEVEL ANALYSIS
INDICATES A NEAR EQUATORIAL RIDGE TO THE SOUTHEAST OF THE LLCC IS
PROVIDING EASTERLY DIVERGENT FLOW OVER THE AREA. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. BASED ON THE RECENT
CONSOLIDATION OF THE LLCC WITH WINDS BETWEEN 15 TO 20 KNOTS, THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS UPGRADED TO FAIR.
(2) NO OTHER SUSPECT AREAS.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 1.B.(1) TO
FAIR.//
99W集結在6.0N 147.1E，即關島東南偏南約475海里
衛星雲圖顯示LLCC在過去六小時迅速建立，但深層對流持續減弱
一弱暖心系統正在發展
位於系統東南的高脊為99W帶來偏東氣流
99W接近中心最高持續風速約為15-20海里，氣壓為1008mb左右
未來24小時99w增強為TC的機會中等
