THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 6.0N
126.4E, IS NOW LOCATED NEAR 8.2N 126.0E, APPROXIMATELY 230 NM EAST
NORTHEAST OF ZAMBOANGA, PHILIPPINES. ANIMATED INFRARED SATELLITE
IMAGERY SHOWS FLARING CONVECTION OVER MINDANAO WITH NO DISCERNIBLE
LOW LEVEL CIRCULATION (LLCC). A SERIES OF MICROWAVE IMAGES
INCLUDING A 261312Z 89 GHZ AMSU INDICATE THE LLCC HAS MADE LANDFALL
OVER NORTHEAST MINDANAO. UPPER LEVEL ANALYSIS INDICATES THAT THE
SYSTEM IS LOCATED JUST SOUTH OF THE NEAR EQUATORIAL RIDGE UNDER
MODERATE EASTERLY VERTICAL WIND SHEAR. A SURFACE OBSERVATION FROM
DAVAO AT 261100Z SHOWED 1010 MB MSLP WITH A 1 MB INCREASE OVER THE
PAST 24 HOURS WITH LIGHT AND VARIABLE WINDS. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED
AT 12 TO 17 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1010 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS DOWNGRADED TO POOR.
LLCC已登陸
並降為Poor
AT 12 TO 17 KNOTS
很少見JTWC這樣描寫中心風力
THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 8.2N
125.1E, IS NOW LOCATED NEAR 8.9N 120.2E, APPROXIMATELY 160 NM
NORTHWEST OF ZAMBOANGA, PHILIPPINES. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY AND A 270539Z AMSU-B MICROWAVE IMAGE SHOW CURVED
CONVECTION AROUND A WEAK LOW LEVEL CIRCULATION CENTER (LLCC), WHICH
HAS RECENTLY MOVED OVER WARM WATER IN THE SULU SEA. UPPER LEVEL
ANALYSIS SHOWS THE SYSTEM IS LOCATED BENEATH THE NEAR EQUATORIAL
RIDGE AXIS IN AN AREA OF LOW VERTICAL WIND SHEAR. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1009 MB. DUE TO HIGH SEA SURFACE
TEMPERATURES AND IMPROVED CONVECTIVE ORGANIZATION, THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO FAIR.
又FAIR了
