reporter: the kincaide fire is the biggest in the state charring 30,000 acres and destroying 79 buildings including 31 homes. it has 3,000 firefighters working it. the goal is to have it contained by november 7th. so many people in the state are affected by fires in different ways. a grass fire in vallejo shut down interstate 80. 2.3 million people are without power because the utility pg&e proactively put in place blackouts to avoid the wind bringing down charged power lines and starting more fires. but the governor is still not satisfied. difficult calls, professionals need to make them. but a society as industrious and innovative as ours should not have to face the choice between public safety and public blackouts. reporter: a red flag warning will be in effect all throughout the night and not be lifted until 1 11:00 tomorrow
