An escalation in the Palisades fire threatens thousands of properties in the region. More than 5,300 structures have already been destroyed in the region.

A brief break in the dangerous winds fueling California’s destructive blazes allowed firefighters to launch an aggressive bid for control—but it wasn’t enough to knock down Los Angeles’s two biggest fires.

Eleven deaths have been confirmed and more than 12,000 structures have been damaged or destroyed. More than 150,000 people remain under mandatory evacuation orders. Law enforcement sources told The Times that it’s likely many of the small fires will turn out to have been the work of arson.
