Firefighters on Saturday made progress in containing a fast-moving brush fire along Cajon Pass, which has spread to 1,200-acres.
The fire closed Interstate 15 for parts of Friday and left some people in bumper-to-bumper traffic later on, but was flowing Saturday morning.
I-15 is open in both directions but closures may occur periodically due to smoke, according to the San Bernardino National Forest Service.
Officials did warn however, that more closures are possible depending on smoke and fire conditions.
The fire, which broke out around 1 p.m. on Saturday grew to 250 acres in a little more than an hour, and doubled in a little more than two hours. By Friday night, officials said, weather conditions for battling the Hill fire were becoming more favorable, as the winds were easing.Firefighters Contain
U.S. Forest Service spokesman John Miller told The Associated Press that the fire was fueled by winds up to 15 mph and 90 degree temperatures, but by dusk cooler weather and calmer winds helped 750 firefighters surround 20 percent of the blaze.
Reports are that crews were using at least 50 fire engines, four bulldozers, four helicopters and 14 air tankers, including a DC-10 was flown in from Sacramento to help battle the blaze.
At least one home sustained heavy damage, two mobile homes were lost and two other structures were damaged, the San Bernardino National Forest Service told the media.
One firefighter was evacuated from the area for a medical emergency and his condition hasn't been released. Reports are that a second firefighter suffered heat exhaustion.
Authorities have called for the evacuation of several San Bernardino County, Calif. neighborhoods close to the blaze.
