REMARKS:
162100Z0 POSITION 21.2N5  127.4E4
TYPHOON VIOLET (26W) IS MOVING NORTHEAST AT APPROXIMATELY
07 KNOTS. IT HAS WEAKENED OVER THE PAST SIX HOURS AND IS
EXPECTED TO CONTINUE WEAKENING THROUGH THE DURATION OF
THE FORECAST PERIOD. AS TY VIOLET APPROACHES THE INDUCED
RIDGE TO ITS EAST THE SOUTHERLY STEERING COMPONENT IS
EXPECTED TO INCREASE, RESULTING IN A MORE NORTHWARD
MOTION BETWEEN 12 AND 24 HOURS. AFTER 24 HOURS TY VIOLET
IS EXPECTED TO BE FAR ENOUGH NORTH TO MAKE A
NORTHEASTWARD TURN AROUND THE RIDGE. WARNING INTENSITY IS
BASED ON ENHANCED INFRARED IMAGERY ANALYSIS INDICATING
115 KNOT WINDS (DVORAK CI 6.0). WIND RADII AT WARNING
TIME ARE A BLEND OF SYNOPTIC DATA, MICROWAVE IMAGER
(SSM/I) ANALYSIS PROVIDED BY AFGWC (16/09Z), AND
SCATTEROMETRY (16/14Z). NEXT WARNINGS AT 170300Z1 (DTG
170157Z1), 170900Z7 (DTG 170757Z7), 171500Z4 (DTG
171357Z4) AND 172100Z1 (DTG 171957Z0). MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 161800Z6 IS 29 FEET. REFER TO
WWPW31 PGFW FOR ADDITIONAL SEA HEIGHT INFORMATION. REFER
TO TYPHOON TOM (25W) WARNINGS (WTPN31 PGTW) FOR SIX-
HOURLY UPDATES.//
