Flames broke out around 2:00 a.m. at a mushroom farm located along the 8100 block of Gap Newport Pike (Route 41).
Fire department officials initially reported at least a dozen large hay bales burning, but the flames quickly spread due to the high winds still blowing overnight in the area.
Front-end loaders were brought to the scene in an attempt to separate non-burning bales from the burning bales.
Smoke could be seen for miles.
So far, no reports of injuries.
