Marco Noriega, brewmaster at Mount Shasta Brewing Company, said they received the notice to evacuate about an hour ago and he sent the 10 customers and three employees away. He said the power is out and they have received little information.

Smoke is to the north and winds are blowing from the south, keeping the fire away. He sounded calm as he cleaned up.

“I’ve been through it before, so long as the wind stays in the direction it is, I’m all right. But I know the wind switches quickly,” he said by phone.

The National Weather Service issued a red flag warning for Siskiyou County from 11 a.m. to 11 p.m. Friday. Winds were expected to reach up to 31 mph in the Weed area, the weather service said.

In Southern California, firefighters were making progress Friday against two big wildfires despite dangerously hot weather.

Containment of the Route Fire along Interstate 5 north of Los Angeles increased to 37% and it remained at just over 8 square miles (21 square kilometers) in size, a California Department of Forestry and Fire Protection statement said.

Firefighters were focusing on mopping up hotspots and building more containment lines, trying to get most of the hard work done before the midday heat, Cal Fire said.
