The map above shows Gifford’s evacuation area in red and the approximate fire perimeter as a black line. Shown as a gray tone is the perimeter of last month’s Madre Fire, previously the biggest fire of the year; it burned 80,779 acres in the Carrizo Plain area, just east of Gifford.

The Gifford Fire has now burned more than 100,000 acres, according to the latest mapping by Intel aircraft. As of Friday afternoon, the fire spanning San Luis Obispo and Santa Barbara counties had blackened a total of 104,590 acres.

The Gifford Fire was first reported Friday near the Gifford trailhead in Los Padres National Forest, around 15 miles east of Santa Maria. It quickly ballooned to more than 23,000 acres within 24 hours.
