Due to the residual smoke lingering in the region, the Air Quality Alert has been expanded to include all Central and Eastern Washington counties. The Air Quality Alert will expire tomorrow morning at 10am.

We'll return to our normal May air quality conditions by the end of the weekend with the arrival of a cold front.
