AN AREA OF CONVECTION HAS PERSISTED NEAR 1.7N 153.9E,
APPROXIMATELY 120 NM EAST OF CHUUK, FSM. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY (MSI) SHOWS A BROAD AREA OF TROUGHING WITH FLARING
CONVECTION ALONG THE TROUGH AXIS. THE MSI LOOP INDICATES SEVERAL
VORTICES WITH A DOMINANT VORTEX JUST EAST OF CHUUK. UPPER LEVEL
ANALYSIS REVEALS THE SYSTEM IS WELL SOUTH OF THE RIDGE AXIS IN AN
AREA OF LOW (05-10 KNOT) VERTICAL WIND SHEAR AND A DEVELOPING
POLEWARD OUTFLOW CHANNEL THAT IS TAPPING INTO THE STREAM FEEDING
INTO A TUTT CELL TO THE NORTHEAST. NUMERIC MODELS INDICATE
SIGNIFICANT DEVELOPMENT IN 96 HOURS. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
目前對流仍屬散亂狀
還有待發展加強
