The blizzard expected to begin Friday evening may crescendo into flood damage come Saturday morning.
Several areas along the Swampscott waterfront are susceptible to flooding, says town DPW Director Gino Cresta.
They include Humphrey Street from the Lynn line to Monument Avenue; on Puritan Road from Fisherman's Beach to Smith Lane; and on Atlantic Avenue from Beach Bluff to the Marblehead line.
The National Weather Service has declared a coastal flood watch for the entire Massachusetts coast line — including Swampscott.
You've probably heard about the coming storm that's expected to dump one to two feet of snow on much of the state. But early Thursday morning the Weather Service added the flood watch to the blizzard watch already in effect.
Forecasters say "numerous coastal roads" could become impassable Friday evening and during Saturday morning's high tide. In Swampscott Harbor, the Saturday morning high tide — an astronomically high tide — will come at 9:03. It could be accompanied by large waves and a storm surge, the Weather Service warns.
Major coastal flooding could occur around that Saturday morning high tide. If that does actually come to pass, the consequences could be dire — "Some vulnerable homes may be damaged or destroyed," the flood watch says. It also warns that evacuation of some neighborhoods might be called for.
