  • Wildfires

    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, of which almost all fires occurred in Eastern Washington. Eastern Oregon also experienced wildfires, although due to the high elevation, the temperatures were lower and most fires were actually caused by lightning strikes (although the heat made it worse). The heatwave caused the summer to start off dry, making the rest of the season even worse. Because of this, it is thought that the heatwave most likely had a large effect on the fires in Oregon later that year. Overall, the largest fires occurred in the Okanogan Valley of Eastern Washington and British Columbia.
