Wildfires are rampaging across Los Angeles County this week.Hundreds of thousands of people are under evacuation orders or warnings.Insured losses could top $20 billion, JPMorgan analysts estimated the most-ever in California.The Los Angeles area battled a series of massive wildfires Thursday that continued to rip through its picturesque mountains and hillsides creating a hellscape of burned-out neighborhoods and livelihoods that could end up being the most costly fire disaster in California history. JPMorgan analysts said the blazes tearing through the region could lead to more than $20 billion in insured losses and around $50 billion in total economic losses. That would make these conflagrations "significantly more severe" than the Camp Fires that struck the state in 2018 and racked up $10 billion in insured losses, the current record.As of Thursday morning local time, an additional 200,000 people had been placed under evacuation warnings with officials advising them to get ready to leave their homes if the fires raging near their residences got closer.Thick bands of smoke could be seen in several directions from the city's downtown core with at least five fires burning throughout the 4,000 square-mile county that's home to nearly 10 million people.More than 29,000 acres have burned so far and at least 10 deaths have been reported as of 9 p.m. local time on Thursday.And at least 10,000 homes and other structures have been destroyed so far, per the California Department of Forestry and Fire Protection.
