Smoke from a wildfire can bee seen in Rancho Cucamonga, California on April 30, 2014.
A Southern California wildfire that forced the evacuation of at least 1,100 homes has grown to 800 acres.
Fire officials said on Wednesday winds gusting to 60 mph are pushing the flames through the foothills of the San Bernardino Mountains east of Los Angeles, although no homes are in immediate danger.
Officials said earlier that 200 acres had been charred.
Mandatory evacuations were ordered due to the smoky conditions in parts of Rancho Cucamonga, a city of 165,000 people east of Los Angeles.
Several neighbourhoods and at least seven schools have been evacuated.
There's no word on what sparked the blaze, but it comes in the midst of a heat wave that's created extreme fire danger.
