TYPHOON (TY) 13W (MALAKAS), LOCATED APPROXIMATELY 245 NM EAST- SOUTHEAST OF TOKYO, JAPAN, HAS TRACKED NORTH-NORTHEASTWARD AT 32 KNOTS OVER THE PAST SIX HOURS. POSITION IS BASED ON VISUAL IMAGERY AND A 242334Z ASCAT IMAGE. THE WINDFIELD INDICATED BY THE ASCAT IMAGE VERIFIES A DRAMATIC SHIFT IN THE WINDFIELD AHEAD OF THE STORM WHICH SHOWS A DEVELOPING WARM FRONT. THE SYSTEM IS BEGINNING TO TAKE ON FRONTAL CHARACTERISTICS ON BOTH SIDES AS COOLER DRIER AIR IS SPILLING OVER HONSHU AND FEEDING INTO THE WESTERN QUADRANT OF THE SYSTEM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 242239Z SSMIS IMAGE ALSO CONFIRM THAT THE SYSTEM IS RAPIDLY UNDERGOING EXTRA- TROPICAL TRANSITION. EYE-WALL COLLAPSE IS NOW EVIDENT AND WATER VAPOR IMAGERY SHOWS THAT THE UPPER LEVELS OF THE SYSTEM HAVE COUPLED WITH THE MID-LATITUDE FLOW. TY MALAKAS' UPPER LEVEL CIRCULATION CENTER AND LOW-LEVEL CIRCULATION CENTER HAVE NOW DE-COUPLED. DEEP CONVECTION ASSOCIATED WITH THE STORM IS SHEARING TO THE NORTHEAST AND IS NEARLY COMPLETELY GONE OVER THE EQUATORWARD QUADRANTS OF THE SYSTEM. AVAILABLE DYNAMIC AIDS ARE IN TIGHT AGREEMENT IN PROJECTING THE STORM TO MOVE RAPIDLY INTO A BAROCLINIC ZONE EXTENDING FROM NORTHERN HONSHU INTO THE WESTERN PACIFIC, WHERE IT WILL BECOME A STORM FORCE MID-LATITUDE LOW PRESSURE SYSTEM BY TAU 12. THE FORECAST IS BASED ON THE CONSENSUS TRACK. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WARNING CENTER (NAVMARFCSTCEN). THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 250000Z IS 33 FEET.// +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
