A brush fire in Canyon Country was threatening structures and running downhill Thursday, fire officials said.

The brush fire, reported in the 31600 block of Tick Canyon Road burned through roughly 200 acres very rapidly Thursday afternoon by 2 p.m., Los Angeles County Fire officials said.

One structure was already ablaze, as the line of fire quickly advanced on a home, with firefighters poised to protect it. 

The fire comes as some 80 homes were evacuated overnight in San Bernardino County as a 70-acre blaze forced road closures. A 10,000-acre blaze was also burning in the Bay Area. 

Utility companies including SoCal Edison preemptively cut power to thousands of homes Thursday in an effort to diminish the threat of wildfires. See all locations here.
