A new fire broke out near Los Angeles’ Bel Air neighborhood early on Thursday as the Hughes fire which was first reported a day earlier in northern Los Angeles County grew rapidly to set ablaze more than 10,000 acres, prompting authorities to issue evacuation orders and warnings to more than 50,000 people.

Firefighters in Southern California are battling two new wildfires that erupted early Tuesday morning, prompting fresh evacuations as dangerous fire weather conditions continue to grip the region. The Lilac Fire was first reported around 1:20 a.
