UPDATE: Bay Area Air Quality Advisory Issued Due to Fires, Smoke

Smoke from wildfires in southern Oregon has persisted in the Bay Area, prompting the extension of an air quality advisory in the region through Sunday, according to the Bay Area Air Quality Management District.

The BAAQMD is extending an ongoing air quality advisory because fine particulate concentrations and visibility are expacted to be impacted. Air quality is not, however, expected to fall below federal health standards.

There was a light smoky haze over parts of the Bay Area on Friday, but Air District spokesman Ralph Borrmann said that it doesn't present a health concern. If there's additional smoke, and smoke closer to ground level, it could become more of an issue, he said.

"We're not getting exceedances of federal health standards - the smoke is higher aloft, not at ground level where our monitors would pick it up," Borrmann said.

Barring a major influx of such smoke, Bay Area air quality is expected to remain in the "moderate" range, and no "Spare the Air" alert is expected to be called, Borrmann said.

Anyone who smells smoke is advised to stay inside if possible and keep windows and doors closed. People can set air conditioning units and car vent systems to re-circulate so outside air does not move inside, according to the air district.
