REMARKS:
150300Z9 POSITION NEAR 16.3N0 83.7E8.  ANIMATED INFRARED SATELLITE
IMAGERY INDICATES TROPICAL CYCLONE 06B HAS TRACKED TOWARDS THE
NORTHWEST OVER THE PAST 12 HOURS. ADDITIONALLY, THE SYSTEM HAS
SLOWED TO 6 KNOTS.  THE WARNING POSITION AND INTENSITY ARE BASED ON
142330Z3 INFRARED SATELLITE IMAGERY. TROPICAL CYCLONE 06B IS
EXPECTED TO CONTINUE TOWARDS THE NORTHWEST OVER THE NEXT 24 HOURS
UNDER THE INFLUENCE OF A WEAKNESS IN THE HIGH PRESSURE RIDGE TO ITS
NORTHEAST. THE SYSTEM IS ALSO EXPECTED TO MAINTAIN ITS CURRENT
INTENSITY FOR THE NEXT 12 HOURS AS TC 06B REMAINS OVER WARM WATER.
AFTERWARDS, TC 06B IS FORECAST TO WEAKEN DUE TO INCREASED VERTICAL
WIND SHEAR AND INTERACTION WITH LAND. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 150000Z IS 18 FEET. REFER TO WWIO31 PGFW FOR ADDITIONAL
SEA HEIGHT INFORMATION. NEXT WARNINGS AT 151500Z2 (DTG 151351Z6)
AND 160300Z0 (DTG 160151Z4).//
