Dozens of towns still have no power or are close to 100 percent outages, which is creating a demand for shelters.
About 93 percent of Middletown is in the dark and the shelter at Middletown High School was already at capacity on Monday.
Mayor Sebastian Giuliano said city officials are doing everything in their power to accommodate people.
Wallingford is sending in volunteers to help out and police in Old Saybrook, where about 10 customers have no power, are sending officers.
Giuliano told the Middletown Patch that moods were positive “but two days of this and I think their nerves are going to get frazzled.”
