An air quality advisory was released by the Bay Area Air Quality Management District for Wednesday as Northern California wildfires are expected to emit smoke that can reach the region.

In recent weeks, the air district gave out a series of air quality advisories because of the blazes. The forecast on Wednesday, meanwhile, was released due to the smoky and hazy conditions, especially in North Bay.

The district said that air quality, however, is not expected to become worse to surpass deferral health standards and trigger a Spare the Air alert as well as the wood burning ban.

Those who are affected can smell the smoke and are told to remain indoors with doors and windows shut. To prevent air from the outside from getting inside, it is advised to set air conditioning and car vent systems to re-circulate, KTVU reported.
