Wildfires[edit]
The heat wave was responsible for multiple wildfires in the Southern Interior of British Columbia. The heat wave was also most notably responsible for causing the worst wildfire season in Washington state history,[3][4] of which almost all fires occurred in Eastern Washington. Eastern Oregon also experienced an abnormally severe wildfire season, although temperatures here were lower due to higher elevations and many of the fires were actually caused by lightning strikes.[5] The heatwave caused the summer to start off dry, making the rest of the wildfire seasons in both states far worse than normal.[6] Overall, the largest fires occurred in the Okanagan Valley of Eastern Washington and British Columbia.[citation needed]
