LOS ANGELES (AP) — Fire lines have been established around nearly a third of one of the largest wildfires in California history, but danger remains. Coastal communities in Ventura and Santa Barbara counties were warned Wednesday that they're still at risk if unpredictable winds whip up again and fan the flames. The National Weather Service extended warnings through Friday of extreme fire danger conditions throughout much of Southern California due to lack of moisture along with a possible increase in wind gust speeds at the end of the week. Firefighters made some progress Wednesday on corralling the so-called Thomas Fire, which has spread into national forest land northwest of Los Angeles.
