Smoke from multiple wildfires merges into blanket over Bay Area, video shows

Smoke from multiple California wildfires is combining to create a thick cloud that’s so extreme it has been caught on satellite images, video shows.

The dark smoke came from the quickly spreading Glass Fire and several wildfires in Northern California, the San Francisco Chronicle reported.

“On top of the elevated smoke plume from the Sierra wildfires that will gradually move closer to our area this evening, there is now a thin line of elevated smoke coming from the Glass Fire that is being driven by offshore winds into Sonoma and Marin counties,” the National Weather Service Bay Area tweeted on Sunday.

As the hazy smoke from multiple wildfires blanketed Napa County and the Bay Area again, air quality became unhealthy for sensitive groups, according to AirNow. The air quality could get even worse in the North Bay because smoke from the Complex Fire in August is moving south, according to ABC 7.

The Glass Fire spread quickly overnight from 2,500 acres Sunday evening to 11,000 acres by Monday morning, The Sacramento Bee reported. It’s uncontained and threatens more than 8,500 structures, according to the newspaper.

“There have been numerous evacuations, that’s been going on through the night,” Cal Fire spokesman Tyree Zander told The Sacramento Bee on Monday. “They have a rapid rate of spread, a dangerous rate of spread.”
