More than 600 acres, a chicken house and two barns have already burned in what was an out of control grass fire south and east of Southwest City this evening.

The fire is being fought by firefighters from three states including Jay Fire Department.

Witnesses say you can see the smoke from Grove and even from Bentonville, Ark.

Fire officials said the fire was spreading so fast it was "jumping roads like they weren't even there."

Although the fire is reportedly 80 percent contained at this time, fire departments are expected to be with the fire all night especially since the National Weather Service is calling for increased winds.

How the fire started has not been determined.
