NEWBURY — Like a life-sized doll house, the home at 31 Annapolis Way is missing a wall and floor, lost to pounding surf, as yet another storm ravaged the Massachusetts coast, endangering more beachfront homes on Plum Island.

“This used to be a bedroom,” said Stephen Breshnahan of Newburyport, waving an arm across the back of his mother-in-law’s house as he stood in pelting, freezing snow and rain during high tide on Monday.
