Watch Duty, a nonprofit that tracks wildfires, said that as of 11:26 p.m. the fire was estimated to be 10 acres, burning in heavy brush east of the freeway in the Sepulveda Pass. By about 12:23 it had grown to 20 acres, though fire crews were making good progress on the blaze, Watch Duty reported.

A new fire broke out Wednesday night along the 405 Freeway in the Sepulveda Pass. The fire was burning on the east side of the 405 near the Sepulveda Fire Road. Winds were at about 5 mph, according to the Los Angeles Fire Department.

Firefighters made progress on the more than 10,000-acre Hughes Fire Friday, which sent thousands fleeing after sparking near the Los Angeles County community of Castaic. Some mandatory evacuation orders have been downgraded to warnings while containment of the wildfire rose over Thursday.

Evacuation orders and warnings were issued to more than 31,000 people in the vicinity of two new wildfires north of Los Angeles on Wednesday.
