According to local fire officials, buildings in California’s Napa and Sonoma counties were being evacuated on Monday morning, after multiple wildfires began spreading throughout the area with a thick smoke and large flames. According to the state Department of Forestry and Fire Protection, the fire was burning in the hills above Napa County and had damaged several buildings. As of Monday morning, firefighters have continued to struggle to contain the fire. Officials said dry winds were fanning the flames and asked residents in mandatory evacuation zones to leave immediately.

RENO — There’s enough wildfire activity in California and Nevada to blanket much of both states with a layer of smoke in the coming days.

In California alone more than 140,000 acres are burning in large, wildland fires throughout the state. A fire in rough terrain near Reno is also contributing to smoke in northern Nevada.

In just the past two days, fires in California’s wine country are thought to have produced as much small particulate matter as all the vehicles in the state produce in a year.

“It’s a lot,” said Sean Raffuse, an air-quality analyst at the Crocker Nuclear Laboratory at University of California in Davis.

Although the early estimates are rough, Raffuse said the fires in the wine country have probably produced about 10,000 tons of PM 2.5, an air pollutant that’s the main cause of haze in the United States.
