According to officials, Oklahoma City and Deer Creek firefighters responded to a grass fire that started just south of N.W. 192nd Street and west of N. Portland Avenue.
News 9 pilot Jim Gardner said the fire burned towards N.W. 178th Street, and police had to evacuate a nearby Sonic, Dollar General, a convenience store and a strip mall.
While firefighters worked to extinguish the fire, the wind shifted from the northwest to the southeast, pushing the smoke towards the evacuated businesses.
Gardner said a farmer lost some hay bales, but no structures were damaged.
As of 3:45 p.m., the Oklahoma City Fire Department said 320 acres have burned.
N. Portland Avenue is closed between N.W. 178th and N.W. 192nd streets. Drivers are encouraged to avoid the area.
Gardner said the dry conditions and winds between 22 and 30 mph caused this to be a fast-moving fire.
Yukon and Piedmont Fire Departments assisted the Oklahoma City and Deer Creek firefighters with this grass fire.
