Firefighters reported some progress fighting the wildfires that have charred hillsides, homes and streets in Los Angeles County, but the strong winds that fanned the flames were expected to pick up again on Friday,

Fierce winds fueled new fires and made it harder to contain the largest blazes, which have destroyed whole neighborhoods and have become some of the most devastating in California’s history.

A new fire — the Kenneth Fire — erupted Thursday afternoon, so far spreading across 960 acres in Los Angeles and Ventura counties. The California Department of Forestry and Fire Protection says that blaze is 0% contained.
