.Synopsis for Massachusetts and Rhode Island coastal waters...
Tropical Storm Jose has stalled well southeast of Nantucket and
will slowly drift toward the southwest and weaken over the next  few
days. This will maintain strong winds along with large waves  and a
chaotic sea. Scattered rain bands will persist, especially across
the southern half of the waters. A ridge of high pressure  may build
over the waters for Sunday and Monday. Hurricane Maria  may approach
the southern waters mid week next week therefore  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
follow the Current Hazards link above the map on the left.
