EDMOND, Okla. (AP) — A wildfire fueled by dry vegetation and strong winds has spread to structures in central Oklahoma.

Firefighters responded Tuesday to reports that several structures were engulfed in flames as the fire spread north of Edmond. Officials say several residences have been damaged or destroyed by flames. There were no reports of injuries or evacuations.

The fire has consumed about 50 acres of land behind wind gusts of up to 36 miles per hour. The cause of the blaze has not been determined.

Additional wildfires were also reported near Tuttle in Grady County and east of Shawnee in Pottawatomie County.

A red flag warning is in effect for central and western Oklahoma until 7 p.m. The National Weather Service says unseasonably high temperatures and low humidity contribute to the wildfire threat.
