The highest water levels and greatest impacts are forecast to occur during the Sunday morning high tide, when isolated Moderate coastal flood impacts are possible along the back bays. Ice from the back bays could get pushed onshore during high tide, and flood waters could freeze on roadways, further complicating impacts.

Do not leave your vehicle at a location that is prone to tidal flooding. Do not drive your vehicle through flood waters. The water may be deeper than you think it is. You will be putting yourself in danger and your vehicle may be damaged, leading to costly repairs.
