The fires burning in Washington state's wildland-urban interface zones highlight the risk of building homes in these areas, where thicker vegetation combines with houses to pose greater danger. 

As Kylie Mohr explains in High Country News, "Almost a third of housing nationwide today is situated in the wildland-urban interface, according to 2020 Forest Service research. As climate change primes the landscape for wildfires, these places are increasingly in harm’s way." Homes in Spokane County face more fire risk than 82% of counties nationwide. As high winds fanned the flames in the recent fires, "For the first time in Washington state history, the National Weather Service designated a 'particularly dangerous situation.'"
