Firefighters took advantage of cooler temperatures Wednesday and increased containment on several destructive wildfires in California just ahead of another forecast of triple-digit heat this weekend.
The slight cool-down kept fire activity at minimal levels and allowed firefighters to improve containment lines around the blazes. The fires, which erupted over the weekend amid a searing heat wave, have destroyed more than four dozen homes statewide.
Wildfire risk will increase this weekend, as a massive high-pressure system settles over the American Southwest. That system is expected to raise temperatures in Northern California by as much as 10 degrees and 3 to 6 degrees in Southern California, according to the
Light "sundowner winds" could be problematic for firefighters battling the 11,920-acre Whittier fire in Santa Barbara County, forecasters said. The strong offshore winds are formed by a building high pressure, which pushes the northerly gusts through canyons and passes in the Santa Ynez Mountains.
"This will make conditions in and around the Whittier fire worse," meteorologist Andrew Rorke said in a weather statement.
Fire crews tackling the Whittier fire in the Los Padres National Forest put out hot spots overnight and constructed new containment lines to hold the massive blaze, according to the U.S. Forest Service. The fire was 48% contained.
The blaze, which started Saturday along Highway 154, has destroyed eight homes and 12 outbuildings south of Lake Cachuma, and prompted the evacuation of more than 3,500.

Despite the warm temperatures and low humidity, nearly 1,700 firefighters have surrounded the blaze, strengthened containment lines and slowed its growth, Cal Fire said. The fire, which was 60% contained, still threatens 606 structures.
