Santa Barbara County fire agencies were responding to a 5-acre vegetation fire at Highway 101 and Zaca Station Road north of Buellton on Thursday afternoon, which resulted in the closure of the highway in both directions.
Santa Barbara County fire officials called in air resources, and at least two tankers and a helicopter responded to the scene, spokesman Mike Eliason said.
Winds were reportedly calm in the area, but downed, live power lines made the scene difficult for firefighting resources to access, Eliason added.
The fire is burning near Highway 101 and Highway 154, north of Buellton and the Santa Ynez Valley.
California Highway Patrol began stopping traffic at 12:23 p.m.
No further details were available.
