REMARKS:
140300Z POSITION NEAR 34.2N 149.9E.
TROPICAL DEPRESSION (TD) 17W, LOCATED APPROXIMATELY 480 NM EAST OF
TOKYO, JAPAN HAS TRACKED NORTH-NORTHEASTWARD AT 13 KNOTS OVER THE
PAST SIX HOURS. THE SYSTEM CONSOLIDATED SUFFICIENTLY TO WARRANT
THE ISSUANCE OF A TROPICAL WARNING. TD 17W IS ACCELERATING INTO
THE MIDLATITUDE WESTERLIES WITH IMPROVED CONVECTIVE BANDING AND
DEVELOPMENT OF A WEAK MICROWAVE EYE FEATURE. A 132037Z TRMM IMAGE
DEPICTS CONVECTIVE BANDING WRAPPING FROM THE SOUTHEAST QUADRANT
INTO THE WEST QUADRANT. THE SYSTEM IS TRACKING OVER WARM SST NEAR
28C BASED ON AN OBSERVATION FROM BUOY 43545 WITH SLP OF 1004.3 MB.
THIS OBSERVATION IS ABOUT 20 NM NORTHWEST OF THE CENTER, AND ALONG
WITH DVORAK INTENSITY ESTIMATES OF 25-30 KNOTS, JUSTIFIES THIS
WARNING. THERE IS EVIDENCE THAT THE SYSTEM HAS ALREADY BEGUN EXTRA-
TROPICAL TRANSITION (ETT) AND IS FORECAST TO ACCELERATE NORTHEASTWARD
AND COMPLETE ETT BY TAU 12. 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 140000Z IS 6 FEET. REFER TO
TYPHOON 15W (SINLAKU) WARNINGS (WTPN31 PGTW) FOR SIX-HOURLY
UPDATES.//
