The Santa Ana winds, which blow through in the fall, bring high fire danger because their powerful gusts can whip flames into infernos.
Low humidity and high temperatures accompanied by a seasonal blast of Santa Ana winds have been keeping Southern California fire agencies on alert.
The National Weather Service said dry, gusty winds would continue Saturday before dying down towards the end of the weekend.
Firefighters moved quickly Friday to control small brush fires across the region.
A blaze that burned through patchy brush in the Fontana area below the Cajon Pass was held to about 10 to 15 acres, said San Bernardino County fire spokesman Eric Sherwin. More than 150 firefighters were brought in from many agencies. No structures were damaged.
Division Chief John Salvate said there had been concerns the fire could reach some homes due to sustained winds of 25 mph and 35 mph and gusts of up to 50 mph earlier in the day.
In Los Angeles County, firefighters held a fire to 1 acre along a road in the Santa Monica Mountains near Malibu.
Crews successfully contained a slow-moving brush fire that spread over about 2.5 acres on a hillside in eastern San Diego County.
The Santa Ana winds, which blow through in the fall, bring high fire danger because their powerful gusts can whip flames into infernos. The Santa Anas have been involved in many of Southern California's most destructive wildfires.
The winds are spawned by surface high pressure over the interior of the West that sends a cold, dry air mass toward Southern California. The air then warms and speeds up as it descends through mountain passes and canyons and rushes toward the coast and offshore.
Forecasters said the high pressure will slowly weaken through Sunday, gradually reducing wind speeds. A high wind warning was reduced to an advisory, but forecasters said there was a slight chance of an isolated gust to 58 mph or greater in some passes and canyons.
A 66 mph gust was reported before dawn Friday, the weather service said.
State and local fire agencies had prepared for Thursday's arrival of the wind event by staffing additional fire engines and positioning them in strategic locations.
With the improving outlook, Los Angeles city and county deactivated their emergency operations centers but were continuing to monitor the situation, the county Office of Emergency Management said in a statement.

As the Santa Ana winds kick up this weekend, long-time Californians know far too well that wildfires could spring up at any moment, as fire season in our region is nearly year-long. Herewith our primer on how to prepare for — and survive — a California fire.

Fire near the Getty Center close to the 405 freeway on Friday.
Firefighters continue to battle the brushfire for a second day in the hills around Sepulveda Blvd. near the Getty Center Saturday. The wildfire that started Friday scorched approximate 90 acres near the 405 freeway and is about 40 percent contained according to the Los Angeles County Fire Department.
"Our focus is to be 100 percent," LAFD spokesman Brain Humphrey said Saturday. "But the most important thing is there were no injuries, no structure damage, and the impact to wildlife is minimal. That's amazing."
Humphrey stressed that containment estimates shouldn't be used as a bellwether statistic.
"There were no firefighter injuries. We are thrilled by that. That's the only real metric that matters," Humphrey said, adding that crews will be working throughout the weekend and they hope to have the fire fully contained by Sunday.

U.S. Forest Service firefighters stand near flames at the Williams fire in the Angeles National Forest on Sept. 4, 2012 north of Glendora.
Despite Wednesday's forecast packing a possible fire-starting lightning risk, raindrops from the remainder of a tropical storm in the region could help the fight against a 3,800-acre blaze in the San Gabriel Mountains northeast of Los Angeles
The area, located in Angeles National Forest, began to burn on Sunday, and was 24 percent contained before the rain started. The blaze called more than 1,100 firefighters to battle in the treacherous terrain -- at least seven responders have sustained injuries.
The fight is currently contained in the mountains and has not moved toward nearby foothill cities. Officials expect it to be fully surrounded on Sept. 13.

Critical fire weather conditions could occur through 5 p.m. Wednesday for the mountains, valleys and deserts of Los Angeles, Ventura and Santa Barbara counties.
According to forecasters, thunderstorms containing little or no rainfall -- but with potential for dry lightning and wind gusts -- could occur as low pressure drops along the California coast.
Meteorologist Stuart Seto told KPCC that dry lightning strikes could fuel wildfires.
"There’s not a lot of precipitation with these storms. So it’s like regular lightning, but the precipitation isn’t there to put out the fires. And also with these thunderstorms, there could be gusty outflow winds. And that’s mainly winds that are coming out of thunderstorms that could enhance some of the fires."
