.Synopsis for Massachusetts and Rhode Island coastal waters...
The remnants of Jose centered about 150 miles southeast of
Nantucket will continue to weaken and slowly drift east through
Sunday. High pressure will build over the waters 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
