At least 10 people have died and at least 1,500 homes, businesses and other structures have been destroyed as more than 14 fires ravaged eight counties throughout Northern California on Monday, authorities said, according to the Los Angeles Times.

The Sonoma County Sheriff's Office reported seven fire-related deaths late Monday. Two people died because of the Atlas fire in Napa County, said a CalFire spokesperson.

One person died as result of the Redwood Valley fire in Mendocino County.

Earlier on Monday, California Governor Jerry Brown declared a state of emergency for much of Northern California and beyond because of the multiple wildfires.

The declaration covers Napa, Sonoma and Yuba counties.
