有何用??
沒有AREA會受影響
THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 9.8N
109.3W IS NOW LOCATED NEAR 10.0N 110.2W, APPROXIMATELY 705 NM SOUTH-
SOUTHWEST OF PUERTO VALLARTA, MEXICO. RECENT ANIMATED MULTISPECTRAL
SATELLITE IMAGERY SHOWS WIDESPREAD THUNDERSTORMS ASSOCIATED WITH A
PERSISTANT CLUSTER OF CONSOLIDATING DEEP CONVECTION, HOWEVER, THE
SYSTEM CONTINUES TO BECOME BETTER ORGANIZED AS THE DEEP CONVECTION
IS BEGINNING TO WRAP AROUND THE LOW-LEVEL CIRCULATION CENTER (LLCC).
UPPER-LEVEL ANALYSIS INDICATES THAT THE SYSTEM LIES JUST TO THE
SOUTH OF THE RIDGE AXIS, IN AN AREA OF MODERATE DIVERGENCE AND LIGHT
VERTICAL WIND SHEAR (10 TO 15 KNOTS). A 221241Z 91H SSMIS MICROWAVE
IMAGE SHOWS A CONSOLIDATING LLCC WITH A CURVING BAND OF DEEP
CONVECTION ALONG THE NORTHERN PERIPHERY OF THE SYSTEM. A 220421
ASCAT IMAGE DEPICTS A SLIGHTLY ELONGATED LLCC, WITH 15 TO 20 KNOT
WINDS WRAPPING INTO THE SYSTEM ALONG THE SOUTHERN AND EASTERN
QUADRANTS, WITH LIGHTER 5 TO 10 KNOTS ALONG THE WESTERN SIDE OF THE
LLCC, WHICH IS ALSO CONFIRMED BY A 220603Z PARTIAL OCEANSAT PASS.
THE SYSTEM IS DEVELOPING A POLEWARD OUTFLOW CHANNEL DUE INTERACTION
BETWEEN THE AFOREMENTIONED RIDGE TO THE NORTH, AND AN UPPER-LEVEL
TROUGH TO THE NORTHWEST. SEA SURFACE TEMPERATURES IN THE REGION ARE
ESTIMATED AT 26-29 DEGREES CELSIUS AND WILL REMAIN FAVORABLE FOR
DEVELOPMENT AS THE SYSTEM CONTINUES TO TRACK WEST-NORTHWESTWARD OVER
THE NEXT 12 TO 24 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1007 MB. DUE TO INCREASED CONSOLIDATION OF THE LLCC AND
THE FAVORABLE UPPER-LEVEL CONDITIONS, THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT
24 HOURS IS HIGH. |
