The Valley fire in California's Lake County is spreading at "astonishing" speed: In less than 24 hours, it's grown to more than 40,000 acres.
"Several buildings have already been destroyed and hundreds more are threatened tonight. Right now, four firefighters are in the hospital after getting hurt in what has turned into an absolutely massive blaze," said KGO-TV's Larry Beil. (Video via KGO-TV)
It's the latest fire in what has been a punishing season for California. The California Department of Forestry and Fire Protection's numbers show as of Sept. 5, fires have burned close to 150,000 acres this year.
Meanwhile, hundreds of firefighters are on-scene or on their way to the Valley fire. Officials have yet to start tracking its containment.
