The Bay Area Air Quality Management District has issued a fourth straight Spare the Air alert for Thursday, Halloween, as smoke from the Kincade Fire in Sonoma County continues to impact the region.
The air district is forecasting air quality to be moderate in much of the Bay Area, but it will likely still be unhealthy in parts of the North Bay such as Windsor and Santa Rosa.
The Kincade Fire has burned more than 76,000 acres as of Wednesday morning and is not expected to be fully contained until Nov. 7, according to Cal Fire.
