Cooler weather helps fire crews corral a third of California’s largest blaze of year

Firefighters make advances on wildfire that has burned 627 sq miles, but return of high temperatures may help it grow

Fire crews battling California's largest wildfire this year have corralled a third of the blaze aided in part by cooler weather, but a return of triple-digit temperatures could allow it to grow, fire officials said Sunday.

Cooler temperatures and increased humidity gave firefighters a great opportunity to make some good advances" on the fire in the Sierra Nevada foothills, said Chris Vestal, a spokesperson for the California department of forestry and fire protection.
