Gusty northeast winds will continue across portions of the Southern California mountain ranges and favored canyons and passes before weakening overnight. The strongest gusts are expected to reach 40 to 50 mph, well below the 90 to 100 mph gusts that impacted communities near Los Angeles six days ago. Very dry conditions and offshore winds over the region will continue to create enhanced fire danger through Wednesday morning.

Initial damage assessments continue in Los Angeles County.
