SAN FRANCISCO (KGO) -- Firefighters in the Bay Area are racing to slow the spread of wildfires that burned nearly one million acres in a week and destroyed hundreds of homes.
The fires have killed five people, torched nearly 700 homes and other structures and forced tens of thousands from their houses.
Light winds, cooler nighttime weather helped fire crews make a bit of progress on Saturday. But their efforts could be hurt by warm, dry weather, erratic wind gusts and lightning in the forecast.
