AN AREA OF CONVECTION HAS PERSISTED NEAR 14.8N 148.6E,
APPROXIMATELY 245 NM EAST-NORTHEAST OF GUAM. ANIMATED MULTISPECTRAL
IMAGERY SHOWS A BROAD AREA OF WEAK CYCLONIC TURNING WITH ISOLATED
POCKETS OF DEEP CONVECTION. A 042019Z QUIKSCAT PASS SHOWS A CLOSED
CIRCULATION WITH 10 TO
15KT UNFLAGGED WINDS AROUND AN ELONGATED
CENTER. EVIDENT TO THE SOUTHWEST OF THE CIRCULATION IN THE QUIKSCAT
PASS IS A LARGE FIELD OF STRONGER WINDS ASSOCIATED WITH THE GRADIENT
FLOW. A 050007Z AMSU IMAGE SHOWS SOME EVIDENCE OF A CURVED INFLOW
PATTERN ON THE SURFACE WITH ISOLATED POCKETS OF UNORGANIZED DEEP
CONVECTION TO THE SOUTH AND SOUTHWEST OF THE LOW LEVEL CIRCULATION
CENTER. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR
1009 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS
IS POOR.
JTWC升格POOR了!!
目前所處風切微弱,未來還將更加減弱
有機會進一步發展!!
