Due to weather conditions Butte County officials extend the Check Before You Light Advisory for the Chico area. According to a Butte County Air Quality Management District press release, a strong high pressure weather system is creating an extended period of weak winds and cold nights. It is also creating strong pollution-trapping inversions. That's why the Butte County Air Quality Management District is asking residents in the Chico area to refrain from using their wood stoves and fireplaces today until midnight tonight. Officials say the air quality is expected to be the poorest during the evening and overnight hours when inversions trap wood smoke close to the ground.
