2018 Russian wildfires
On July 24, the U.S. National Weather Service said smoke had crossed the Canada-U.S. border and reached Bellingham, Washington. Siberian fires were partly blamed by Environment Canada which issued an air quality statement on July 25 for Prince George, BC. On July 29, the Puget Sound Clean Air Agency stated the Puget Sound region would experience "moderate air quality at times with some upper level smoke making for pretty sunsets. This smoke comes from distant fires, mostly originating from Siberia."
