Included in flood watches are Worcester County, Middlesex County, and much of Essex County along with Southern New Hampshire. High wind warnings are in effect along coastlines south of Boston and also include the islands.
A strong cold front and developing low-pressure system arrive early Monday morning and carry hours of steady, heavy rain along with them. Rainfall will total 3-5″ across much of Central Mass, enough to reach our average for the entire month. Scattered occurrences of flash flooding is expected and you need to take caution, especially in the morning hours. In the Boston area, 2-3″ of rain is still expected by lunchtime Monday.

Wind will increase overnight with the highest gusts coming around sunrise. Central Mass will see gusts up to 45 mph, but the potential for gusts as strong as 65 mph will increase farther southeast. The highest wind potential exists for Southern Plymouth & Bristol Counties in addition to the Cape & Islands. Power outages and some minor damage is expected as a result of the wind.
The storm system will wrap up around lunchtime with temperatures sharply dropping into the afternoon.
The Steamship Authority has announced its waiving change and cancellation fees for ferries and from the island for all travel through part of Monday because of the storm. The Steamship Authority says cancellations are likely on the Martha’s Vineyard and Nantucket routes.
