Smoke from Thursday’s Camp Fire in the foothills near Chico is drifting across the Bay Area, but officials in Bay Area counties said there is no local danger of the fire spreading at this point.

In San Francisco, officials issued a city-wide alert warning people who are sensitive to particle pollution to reduce outdoor activity until air quality improves.

Officials for the Bay Area Air Quality Management District issued a smoke advisory for Thursday and Friday, but they noted that conditions in the Bay Area currently do not exceed federal air quality standards.

High winds are carrying the smoke southwest from the 18,000-acre fire, according to a Sonoma County Sheriff’s Office alert. Parts of the Bay Area are under a red-flag warning, which cautions people about increased wildfire risks, through 7 a.m. Friday.

Low humidity levels and offshore winds blowing hot air inland, combined with dried out vegetation, could cause any wildfires that spark to spread quickly.

Pacific Gas and Electric Co. officials said Thursday that they will not preemptively shut off electricity in eight counties in Northern California. The utility did this for the first time in October to prevent downed power lines from igniting a blaze.

Text, emails and automated phone calls lifting the warning are going out to tens of thousands of customers in the area.

People can expect to see hazy skies and smell smoke over the next two days, officials said.
