REMARKS:
260900Z7 POSITION 17.3N1  142.6E3
TYPHOON YATES (28W) HAS TRACKED NORTHWESTWARD AND
INTENSIFIED SLIGHTLY DURING THE PAST 06 HOURS. THIS
SYSTEM IS EXPECTED TO MAKE A TURN TOWARD THE NORTH LATER
IN THE FORECAST PERIOD AS IT TRACKS TOWARD A DEVELOPING
BREAK IN THE SUBTROPICAL RIDGE. TYPHOON YATES MAY BRIEFLY
REACH SUPER TYPHOON INTENSITY (130 KT) LATER TONIGHT NOW
THAT THE NORTHWESTERLY WIND SHEAR HAS DECREASED. A SLOW
WEAKENING TREND IS EXPECTED LATER IN THE FORECAST PERIOD
AS YATES BECOMES ELONGATED NORTH-SOUTH IN THE BREAK IN
THE SUBTROPICAL RIDGE. NEXT WARNINGS AT 261500Z4
(DTG 261351Z8), 262100Z1 (DTG 261951Z4), 270300Z2 (DTG
270151Z6) AND 270900Z8 (DTG 270751Z2). MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 260600Z IS 29 FEET. REFER TO
WWPW30 PGFW FOR ADDITIONAL SEA HEIGHT INFORMATION. REFER
TO TYPHOON ZANE (29W) (WTPN32 PGTW) FOR SIX-HOURLY
UPDATES.//
