Coastal Waters Forecast for Massachusetts and Rhode Island

National Weather Service Boston/Norton MA

for Massachusetts and Rhode Island coastal waters. Low pres system brings the threat of widespread rain, especially the southern waters tomorrow. High pres builds in from the N early next week with the distant system off shore, this could provide a period of strong easterly wind, near gale force, Tue into Wed. There is potential for a coastal low to track northward late week bringing strong winds and rough seas but confidence is low in the exact track and thus impacts.
