Firefighters battled blazes in Contra Costa, San Mateo and Alameda counties on Saturday, after containing several other blazes that have scorched hundreds of acres in the Bay Area over the past few days.
Cal Fire’s incident map shows five “active fires of interest” around the state Saturday night, three of which are burning in counties that surround the San Francisco Bay Area.
The Scenic Fire in Contra Costa County started as a brush fire on Thursday and by Saturday morning was 80% contained, having burned 120 acres. An evacuation warning was issued in Port Costa on Thursday when the blaze burned dangerously close to homes, but authorities gave the ‘green light’ for residents to return later in the day.
Between Pleasanton and Sunol in Alameda County, the Canyon Fire is 70% contained Saturday night and has burned 71 acres. This fire caused the evacuation of a few hundred houses on Thursday but the inhabitants were authorized to return the same evening.
The Edgewood Fire, which has been burning in San Mateo County since the start of the week, was 98% contained by the end of the week and has burned 20 acres, and also triggered evacuation warnings earlier this week.
Several other wildfires have burned across the Bay Area in the past few days. The Kirker Fire in Contra Costa County was 100% contained Friday night after burning 90 acres. The Tesla Fire, south of Livermore, started Thursday evening and burned more than 500 acres, but was 100% contained by Saturday morning.
Smoke was visible in many parts of the Bay Area after hundreds of acres burned in the past few days, but it was high ozone levels that sent air quality plummeting at “moderate” yellow levels in the East Bay on Saturday, with the Peninsula and North Bay in the “good” green air quality range. The forecast looks more yellow, the entire Bay Area Air Quality District is expected to have moderately poor air quality on Sunday.
