REMARKS:
280300Z3 POSITION 21.4N7  138.5E7
TYPHOON YATES (28W) IS MOVING NORTHWESTWARD AT 06 KNOTS.
IT HAS INCREASED INTENSITY DURING THE PAST 6 HOURS AND
DEVELOPED A VERY WARM EYE. DUE TO THIS VERY PRONOUNCED
EYE CYCLE THE SYSTEM IS VERY CLOSE TO SUPER TYPHOON
INTENSITY AT THIS TIME. DURING THE NEXT 24 HOURS THIS
SYSTEM IS FORECAST TO SLOWLY START WEAKENING. WITHIN 72
HOURS WE ANTICIPATE THIS SYSTEM TO BEGIN TRANSITIONING
INTO AN EXTRATROPICAL LOW. NEXT WARNINGS AT 280900Z9
(DTG 280751Z3), 281500Z6 (DTG 281351Z0), 282100Z3 (DTG
281951Z6) AND 290300Z4 (DTG 290151Z8). MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 280000Z0 IS 24 FEET. REFER TO
WWPW31 PGFW FOR ADDITIONAL SEA HEIGHT INFORMATION.
REFER TO TYPHOON ZANE (29W) WARNINGS (WTPN32 PGTW) FOR
SIX-HOURLY UPDATES.//
