SAN FRANCISCO (CBS SF) – A large plume of smoke from several wildfires raging in the state drifted over the San Francisco Bay on Friday, casting a haze on the horizon and triggering an advisory on air quality which will remain in effect until Sunday.
Air quality levels across much of the Bay Area have remained at healthy levels, according to Air Now, a federal government air quality website Friday afternoon. But the levels went from moderately unhealthy to unhealthy when you traveled to eastern Contra Costa County.
For those heading to Lake Tahoe for the weekend, the skies were clouded with smoke from the Dixie and Tamarack fires on Friday. Air quality levels across the lake ranged from unhealthy to extremely unhealthy.
As requested, here are the latest high resolution forecasts for NEAR SURFACE smoke over the next 44 hours. Another loop for suspended smoke at about ridge level will follow shortly. It is more important to focus on the smoke NEAR THE SURFACE. pic.twitter.com/6maez58bLO

Bay Area Air Quality Management District officials said the smoke over the east bay was from the McFarland, Monument and River Complex fires.
They said the plume of smoke rose above 1,500 feet and is not expected to cause widespread poor air quality in the bay area.
“Smoky and hazy skies will be visible throughout the Bay Area and the smoke may impact localized areas such as Napa, Sonoma and Solano counties, as well as higher places,” said the district officials in a statement.
DERIVATIVE SMOKE: Fires north, including the #DixieFire, sent drift smoke over the South Bay area. Expect drift smoke to continue to blow over our area throughout the weekend. #CaWx #CaliforniaForest fires pic.twitter.com/XaAsKp4NDT

Coastal winds were expected to become stronger in the afternoon of Friday and Saturday along the coast, clearing the plume of smoke.
Smoke from the massive Bootleg fire in Oregon last month drifted east and caused hazy skies as far away as New York City, New Jersey and Pennsylvania.
