About a dozen homes in the Sun Valley area were threatened Friday by a fast-moving brush fire that forced a partial closure of the 210 Freeway.
At one point, flames spread in four directions in intense heat and wild winds.
According to the Los Angeles Fire Department spokesman, Erik Scott, police officers realized on Saturday morning that the wildfire had taken more than 5,000 acres, and had to evacuate people from Haven Way, Joaquin Drive, Olney Place, Remy Place, Mystic View Place and View Crest Drive.
Further north in the State of Washington, several fires with the total area of approach 6,000 hectares, caused the evacuation of almost 4,000 homes.
This fire, which was controlled at 10%, was reported during the long weekend of "Labor Day" (labor day in u. s.), a heat wave in the west of the country.
Late on Saturday afternoon local time, he said firefighters were dealing with "very erratic weather and wind".
Those living in the Brace Canyon Park area were ordered to "leave immediately" and head to an evacuation shelter in Sunland, according to an alert issued at 10:35 p.m.by the Los Angeles Fire Department.
The fire continued to burn on multiple fronts Saturday southwest of the 210 Freeway, which remained closed between the 2 Freeway and Wheatland Avenue.More news: Why BRICS meeting is significant for India and China on Doklam backdrop
Thus far, no injuries have been reported.
Garcetti said fire officials have "great confidence" they can defeat the fire, "with the exception if winds just pick up and go wild".
"The primary help we're getting from weather right now is we don't have high winds", Stewart said.
Meanwhile in OR, 140 hikers were being evacuated Saturday after a fire broke out southeast of Portland near the Eagle Creek Trail.
As of Saturday afternoon, more than 500 firefighters were on scene, and a large portion of I-210 remained closed.
But officials say the fire's location in steep and rugged terrain plus hot and dry temperatures are complicating firefighters' efforts.
"We are anxious about the fire hooking, of course, into the southeast, into Glendale and working its way up from there", Garcetti said.
The region was under a red flag warning from the National Weather Service until at least Saturday evening as temperatures were expected to climb above 100 degrees Fahrenheit (37.8 degrees Celsius) with strong winds and low humidity.
