Temporary evacuation sites were established at Benjamin Foxen Elementary School in Santa Maria and the Cuyama Valley Family Resource Center in New Cuyama, Cal Fire said. The agency also reported that Highway 166 was closed between Highway 101 and New Cuyama.

Gifford started along Highway 166 east of Santa Maria, adjacent to the footprint of the year’s previous biggest fire: Madre, which last month burned 80,779 acres in the Carrizo Plain area. Evacuation orders for Gifford covered almost 600 square miles, and Highway 166 was closed between Highway 101 and New Cuyama.

A massive wildfire burning in eastern San Luis Obispo and Santa Barbara counties is now California’s largest wildfire of the year, according to Cal Fire.
