PG&E on Saturday preemptively cut power to around 1,600 customers in Napa, Solano and Yolo counties and another 20,500 in Butte and Yuba counties because of the fire danger.
Several vegetation fires sparked across the region over the weekend, including the Sand Fire in Yolo County, which sent smoke drifting into parts of the Bay Area. As of Sunday evening, the Sand Fire had burned 2,200 acres and was 20% contained, according to Cal Fire.
“Be very careful if you’re out in grassy areas," Tangen said. "With the strong winds and the very dry conditions, any spark could very easily ignite a fire, especially if you’re in a grassy area where the fuel is very dry.”
Tangen said even though the region just finished its wettest May in more than 20 years, finer fuels like grass dry out very quickly.
The high temperatures and winds also prompted the Bay Area Air Quality Management District to issue the year's first Spare the Air smog alert on Sunday — days earlier than the first alert last year — and a second alert for Monday. Officials expect ozone pollution to reach unhealthy levels and are asking people to avoid driving to limit the vehicle exhaust in the air.
