TYPHOON (TY) 13W (MALAKAS), LOCATED APPROXIMATELY 305 NM SOUTH-SOUTHEAST OF TOKYO, JAPAN, HAS TRACKED NORTH-NORTHEASTWARD AT 28 KNOTS OVER THE PAST SIX HOURS. EXTRA-TROPICAL TRANSITION (ETT) IS NOW WELL UNDERWAY IN THE UPPER LEVELS, WHILE THE LOW LEVELS MAINTAIN CORE CONVECTION AND A CLEARLY DISCERNABLE 30 NM EYE. AN UPPER AIR SOUNDING FROM CHICHI JIMA, JAPAN, REVEALS THAT STRONG SOUTHWESTERLIES IN THE STORM'S SOUTHERN QUADRANT EXTEND THROUGHOUT THE TROPOSPHERE WHILE WATER VAPOR IMAGERY SHOWS THE UPPER LEVEL CLOUD SHIELD COUPLING WITH A VIGOROUS JET STREAM TO THE NORTH OF THE STORM. TYPHOON 13W IS EXPECTED TO MAINTAIN VIGOROUS CONVECTION AND WINDS ABOVE TYPHOON STRENGTH OVER THE NEXT 12 HOURS DUE TO GOOD ORGANIZATION AT THE BOUNDARYLEVEL AND WARM SEA SURFACE TEMPERATURES ALONG ITS TRACK. AS TYPHOON 13W CROSSES OVER THE KUROSHIO CURRENT AND ENTERS COOLER WATER NEAR 35 DEGREES NORTH LATITUDE, AND TRACKS UNDER INCREASINGLY HOSTILE VERTICAL WIND SHEAR, IT IS FORECAST TO WEAKEN AND COMPLETE ETT BETWEEN TAU 12-24. HOWEVER, IT WILL MOVE UNDER A DEEP AND NEGATIVELY TILTED MID-LATITUDE TROUGH AND IS EXPECTED TO RE- INTENSIFY AS AN EXTRA-TROPICAL LOW AND MAINTAIN STORM FORCE SURFACE WINDS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 241800Z IS 30 FEET. NEXT WARNINGS AT 250300Z, 250900Z AND 251500Z.// +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
