JTWC (US NAVY & AIR FORCE) REMARKS:
REMARKS (for Meteorologists): 8 PM (12 GMT) SUN 29 MAY POSITION: 34.4N 136.6E.
*TROPICAL DEPRESSION (TD) 04W, SONGDA, MAINTAINED A NORTHEASTERLY COURSE
OVER THE PAST SIX HOURS, TRACKING OVER THE RUGGED TERRAIN OF WAKAYAMA
PREFECTURE. THE OVER-LAND TRACK OF THE SYSTEM HAS RESULTED IN RAPID
WEAKENING. TD 04W HAS NEARLY COMPLETED EXTRA-TROPICAL TRANSITION (XTT)
AND HAS DEVELOPED BOTH WARM AND COLD FRONTAL BOUNDARIES. THE CURRENT
INTENSITY ESTIMATE IS BASED ON OBSERVATIONS FROM MIE PREFECTURE AND
ISE WAN. CHUBU CENTRAIR INTERNATIONAL AIRPORT (RJGG), UPSTREAM OF THE |
LLCC, REPORTED SUSTAINED WINDS RANGING FROM 20 TO 30 KNOTS AND GUSTS
UP TO 40 KNOTS AS THE SYSTEM APPROACHED. TD 04W IS EXPECTED TO RESUME
AN OVER-WATER TRACK WHILE COMPLETING XTT DURING THE NEXT 12 HOURS.
THE RESUMPTION OF AN OVER-WATER TRACK WILL HELP MAINTAIN SYSTEM
INTENSITY UNTIL IT DEVELOPS INTO A GALE FORCE LOW EAST OF THE CHIBA
PENINSULA. 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.//..(more)
