Residents of a Southern California mountain community near the Eaton Fire burn scar were digging out of roads submerged in sludge Friday after the strongest storm of the year swept through the area, unleashing debris flows.

The storm prompted evacuation orders, as officials warned of flash floods in burn-scarred areas near the Eaton and Palisades fires and cautioned drivers to stay off the roads.
