.Synopsis for Massachusetts and Rhode Island coastal waters...
The remnants of Jose centered about 150 miles south-southeast of
Nantucket will continue to weaken and slowly drift southeast  today.
This will keep some fog and showers over the waters this morning.
High pressure will build over the waters tonight and Sunday and
remain in control through midweek. Hurricane Maria  will slowly lift
north and be located off the North Carolina coast by the middle of
next week. It will generate southerly swell  particularly across our
southern outer waters during the first  half of next week. Mariners
should monitor the latest forecasts  from the National Hurricane
Center at www.nhc.noaa.gov.

For information on possible hazardous weather beyond the 24-36
hour forecast period, please visit www.weather.gov/boston and
