Multiple fires raging across the Los Angeles area will cost insurers as much as $30 billion, Wells Fargo and Goldman Sachs estimated in a report released this week. After accounting for non-insured damages, the total costs will balloon to $40 billion, the report said.

As wildfires continue to devastate Los Angeles, leaving thousands displaced and causing widespread destruction, experts urge long-term support and careful giving.

A beefed-up firefighting force was staged around Los Angeles to attack flare-ups or new blazes and anxious residents prepared for more fire danger as winds began to build Tuesday, a week after two massive infernos destroyed thousands of homes and killed at least 24 people.
