Photos show how wildfires are ravaging parts of California's wine country

Massive wildfires engulfed huge swaths of Northern California's wine country early Monday, destroying hundreds of homes and businesses and sending residents fleeing for their lives.

Thousands of people in Napa and Sonoma counties have evacuated the area, which is known for its vineyards and wineries. Three other counties were affected after a series of fires ignited on Sunday and multiplied as strong, dry winds spread the flames over fields and freeways.

By the time most Californians woke for work on Monday, a blaze called the Tubbs Fire had burned at least 20,000 acres in the city of Santa Rosa, the San Francisco Chronicle reported. Nearby schools and hospitals have closed. Power outages are widespread.

The Atlas Fire in Napa devastated an additional 5,000 acres, according to the Chronicle.
