New Smyrna Beach, Fla. ? About 1,000 residents in New Smyrna Beach were ordered to evacuate their homes Sunday as strong winds pushed a brush fire across Interstate 95 toward their homes, authorities said.

More than 100 firefighters were working to contain the blaze that had consumed about 1,000 acres and destroyed at least one home, Volusia County officials said.

“Our problem is no rain, dry conditions and strong winds,” said Greg Dunn, a spokesman for the Division of Forestry.

The cause of the fire was under investigation. One firefighter was treated for smoke inhalation, authorities said.

A seven-mile stretch of I-95 shut down Sunday afternoon because of smoke from other fires that began Friday would remain closed until at least midmorning Monday, according to Florida Highway Patrol.

More than 2,200 wildfires have burned over 44,000 acres in Florida since Jan. 1, according to the state Division of Forestry.
