Multiple wildfires burning across Oregon are contributing to elevated smoke levels in Union County. A layer of stagnant air, known as an inversion, has been holding smoke close to the ground and limiting its ability to clear from the Grande Ronde Valley.
Residents interested in checking current air quality conditions before spending extended time outdoors can visit AirNow.gov for current air quality information, smoke maps, and health recommendations.
Air quality can vary across the County and may change throughout the day as smoke moves and conditions change.
