The homes that are being closed are home to about 1,400 people, and they are expected to remain open through at least Monday night, officials said.
The closure is affecting the communities of Devon and Rockland counties, officials from the Rockland County Board of Supervisors said.
Devon County’s fire chief, Michael Tackett, said in a news conference Tuesday afternoon that a group of vacation homes are being evacuated.
The homes are owned by three families and are being held at a county building that is being used for temporary housing, he said.
“We’re asking people to evacuate immediately, but if you are staying in the county building, stay in your hotel rooms and call 911,” Tackette said.
He said that the county’s Emergency Operations Center had received reports of a fire and “there is a high risk to the community.”
“We need to get everyone out of here as soon as possible,” Tachett said.
There are more than 1,000 vacation homes in the Rocklands County.
The Rockland National Forest Service and the Rock Island National Lakeshore Authority were preparing to clear the beachfront homes as part of a multi-agency response, the county said.
No injuries were reported in the fire, but officials said the fire could have been started by an electrical malfunction or a water leak.
