.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
overnight and Saturday. Large high pressure will begin to build
in from the west Saturday and remain in control of our weather
Sun and Mon. 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
