ST. HELENA, Calif.—A wind-driven wildfire erupted on Sunday in the heart of northern California’s Napa Valley wine country to spread across nearly 2,000 acres (809 hectares), forcing the evacuation of a hospital and hundreds of homes, authorities said.
Fire crews were out in force, scrambling to fend off flames threatening neighborhoods and vineyards at the northern end of the famed wine-growing valley and surrounding hillsides, about 75 miles (120 km) north of San Francisco.
