SEATTLE, WA — The air quality in Puget Sound will be a little bit poorer than normal this week, according to the Puget Sound Clear Air Agency (PSCAA), due to wildfires burning around the region.

Through at least Wednesday, air quality will be "moderate" for healthy adults and sensitive groups for rigorous outdoor activity like biking or running. Air quality will also be moderate for light outdoor activity like walking for sensitive groups.

A shift in wind patterns may clear out the air by Wednesday, according to PSCAA.
