ST. HELENA, Calif. — California firefighters battled destructive new wildfires in wine country north of San Francisco Monday as strong winds fanned flames in the already badly scorched state.

The new fires erupted Sunday in the famed Napa-Sonoma wine region and in far Northern California’s Shasta County, forcing hasty evacuations of neighborhoods.

Flames engulfed the distinctive Chateau Boswell Winery north of St. Helena, The Black Rock Inn in the small community of St. Helena and multiple homes in the city of Santa Rosa, the San Francisco Chronicle reported. Residents of a senior home were among those evacuated.

The Adventist Health St. Helena hospital suspended care and transferred all patients elsewhere, according to a statement on its website.

The wine country blaze had burned 17 square miles as of early Monday, according to the California Department of Forestry and Fire Protection, or Cal Fire.

The wine country has been scarred by terrible fires in recent years, including the 2017 Tubbs Fire that killed 22 people and destroyed more than 5,600 homes and other buildings.

Numerous studies in recent years have linked bigger wildfires in America to global warming from the burning of coal, oil and gas, especially because climate change has made California much drier. A drier California means plants are more flammable.

Evacuations were also ordered in Shasta County as that fire spread.

The causes of both new fires were under investigation.

During the weekend, Pacific Gas & Electric turned off electricity to targeted areas where the winds raised the potential for arcing or other power equipment damage that could spark new fires.

So far this year, more than 8,100 California wildfires have scorched 5,780 square miles, destroyed more than 7,000 buildings and killed 26 people.

Most of the losses occurred after a frenzy of dry lightning strikes in mid-August ignited a massive outbreak of fires.

Fire worries were also developing Monday across Southern California although it was unclear how strong predicted Santa Ana winds would be. Heat and extreme dryness were expected to be problematic nonetheless.

Conditions were also hot, dry and windy in parts of Arizona, where the Sears Fire in Tonto National Forest north of Phoenix has grown to more than 14 square miles since it erupted Friday afternoon. Authorities reported zero containment.
