According to the National Weather Service, for the Coastal Flood Warning, there’s two to three feet of inundation above ground level expected in low-lying areas near shorelines and tidal waterways.

The warning is in effect for Essex, Suffolk, Norfolk, Plymouth, Barnstable, Dukes, and Nantucket counties.

The National Weather Service says many roads near Nantucket Harbor become impassable with 1 to 2 feet of water and affects access to the ferry terminals.

The warning is in effect from 1 a.m. to 7 a.m. on Monday.
