REMARKS:
240900Z5 POSITION 16.2N9  151.2E9
TYPHOON YATES (28W) HAS TRACKED A LITTLE SOUTH OF DUE
WEST DURING THE PAST 06 HOURS ALONG OUR PREVIOUS FORECAST
TRACK AND, AS A RESULT, OUR CURRENT TRACK IS AN EXTENSION
OF OUR PREVIOUS FORECAST TRACK. LATEST SYNOPTIC AND WATER
VAPOR SATELLITE DATA INDICATE THE SUBTROPICAL RIDGE TO
THE NORTH OF TYPHOON YATES HAS CONTINUED TO STRENGHTEN
AND BUILD WESTWARD. THE RIDGE, IN COMBINATION WITH WEAK
BINARY INTERACTION WITH TD 29W, SHOULD KEEP YATES ON A
GENERAL WESTWARD TRACK THROUGH 24-36 HOURS, WITH A RETURN
TO A MORE WEST-NORTHWEST TRACK AS TD 29W PULLS
NORTHWESTWARD AND INCREASES THE SEPARATION BETWEEN THE
TWO STORMS. OUR TRACK FORECAST REMAINS TO THE LEFT
(SOUTH) OF MOST OF OUR NUMERICAL FORECAST GUIDANCE.
NEXT WARNINGS AT 241500Z2 (DTG 241351Z6), 242100Z9 (DTG
241951Z2), 250300Z0 (DTG 250151Z4) AND 250900Z6 (DTG
250751Z0). MAXIMUM SIGNIFICANT WAVE HEIGHT AT 240600Z ARE
23 FEET. REFER TO WWPW30 PGFW FOR ADDITIONAL SEA HEIGHT
INFORMATION. REFER TO TROPICAL DEPRESSION 29W (WTPN 32
PGTW) FOR SIX-HOURLY UPDATES.//
