REMARKS:
221500Z0 POSITION 18.5N4  131.9E4
SUPER TYPHOON ROSIE (10W) IS MOVING NORTH-NORTHWESTWARD
AT 04 KNOTS. THE WARNING POSITION AND INTENSITY ARE BASED
ON 221132Z INFRARED SATELLITE DATA. CURRENT WIND RADII
ARE ADJUSTED USING TWO 220600Z SHIP REPORTS AS WELL AS
220117Z SATELLITE SCATTEROMETRY DATA. SUPER TYPHOON ROSIE
(10W) CURRENTLY DISPLAYS A 15 NM CLOUD FREE EYE. IT IS
FORECAST TO GRADUALLY TURN NORTHWARD AS A MID-LEVEL RIDGE
BUILDS TO THE EAST AND BECOMES THE PRIMARY STEERING
INFLUENCE. IT SHOULD BE NEARING SOUTHERN JAPAN WITHIN 72
HOURS. THIS SYSTEM IS NEAR PEAK INTENSITY AND IS EXPECTED
TO GRADUALLY WEAKEN DURING THE REMAINDER OF THE FORECAST
PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 221200Z IS 35
FEET. REFER TO WWPW31 PGFW FOR ADDITIONAL SEA HEIGHT
INFORMATION. NEXT WARNINGS AT 222100Z7 (DTG 221951Z0),
230300Z8 (DTG 230151Z2), 230900Z4 (DTG 230751Z8) AND
231500Z1 (DTG 231351Z5).//
