REMARKS:
290900Z0 POSITION 27.2N1  126.7E6
TYPHOON ZANE (29W) IS MOVING NORTH-NORTHEASTWARD AT 06
KNOTS. ANIMATED VISIBLE AND INFRARED IMAGERY OVER THE
PAST THREE HOURS INDICATE THIS SYSTEM HAS SLOWED ITS
FORWARD MOTION SIGNIFICANTLY. RADAR ANIMATION FROM THE
WSR-88D DOPPLER RADAR ON OKINAWA ALSO SUGGEST THIS SYSTEM
HAS SLOWED, AND POSSIBLY THAT ITS MOTION IS MORE
NORTHWARD THAN INDICATED BY SATELLITE IMAGERY. OUR SHORT
TERM FORECAST IS FOR TY ZANE TO CONTINUE MOVING VERY
SLOWLY TO THE NORTH-NORTHEAST DURING THE NEXT 12 HOURS,
AND THEN MAKE A SHARP EASTWARD TURN BY 24 HOURS AS THE
SYSTEM MOVES NORTH OF THE SUBTROPICAL RIDGE AXIS AND
COMES UNDER THE INFLUENCE OF THE MIDLATITUDE WESTERLIES.
NEXT WARNINGS AT 291500Z7 (DTG 291353Z3), 292100Z4 (DTG
291953Z9), 300300Z6 (DTG 300153Z2) AND 300900Z2 (DTG
300753Z8). MAXIMUM SIGNIFICANT WAVE HEIGHT AT 290600Z7 IS
24 FEET. REFER TO WWPW30 PGFW FOR ADDITIONAL SEA HEIGHT
INFORMATION. REFER TO TYPHOON YATES (28W) WARNINGS
(WTPN31 PGTW) FOR SIX-H
