.Synopsis for Massachusetts and Rhode Island coastal waters...
Areas of dense fog will impact the waters at times, mainly during
the overnight and early to mid morning hours through Thu. Meanwhile,
large southerly swell from distant Hurricane Maria will continue
to impact our southern waters through the end of the work week. A
cold front from Canada will cross the waters on Thu and force
Maria to pass well southeast of our waters. Large high pres over
the Great Lakes Sat will build across the waters Sun into Mon.

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.
