REMARKS:
201500Z8 POSITION 16.9N6  112.1E5
DURING THE PAST 06 HOURS, TROPICAL STORM BETH (32W) HAS
TRACKED WEST-SOUTHWESTWARD AND CONTINUED TO WEAKEN. MOST
OF THE DEEP CONVECTION WEAKENED OR DISSIPATED NEAR THE
SYSTEM CENTER ABOUT 06 TO 12 HOURS AGO, BUT NEW
CONVECTION HAS RE-DEVELOPED NEAR THE CENTER DURING THE
PAST THREE HOURS AND THIS IS THE REASON WHY WE
HAVEN=T BROUGHT THE INTENSITY DOWN VERY MUCH. ALSO,
20/12Z SYNOPTIC DATA INDICATES A LONG FETCH OF 30 TO 40
KNOT GALES TO THE NORTHWEST THROUGH NORTHEAST OF THE
SYSTEM CENTER WHICH COULD EVENTUALLY WORK INTO THE STORM
CIRCULATION AND HELP GENERATE ONE LAST BRIEF SPIN-UP OF
THE WIND FIELD. MINIMUM SEA-LEVEL PRESSURE IS ESTIMATED
TO BE 991 MB. NEXT WARNINGS AT 202100Z5 (DTG 201955Z2),
210300Z6 (DTG 210155Z4), 210900Z2 (DTG 210755Z0) AND
211500Z9 (DTG 211355Z7). MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 201200Z IS 20 FEET. REFER TO WWPW31 PGFW FOR
ADDITIONAL SEA HEIGHT INFORMATION.//
