The National Weather Service has issued winter storm and coastal flood watches for Swampscott and parts of Essex County in the coming days.
A coastal storm could generate heavy wet snow and high winds and churn storm surges to 3 feet from late Wednesday night through Friday morning.
Offshore waves will likely climb to 25 to 30 feet and surging tides could cause coastal flooding.
It is still early to for forecasters to project snow totals for Swampscott but early estimates say the March storm could deliver 2- to 8-inches.
The snow is expected to be the heavy wet variety that can bring tree limbs down on power wires and knock out electricity.
