As a series of deadly hurricanes have made landfall throughout the US and the Gulf of Mexico, wildfires have gripped Washington and Oregon, two states in the west that are currently dealing with more than a dozen separate wildfires.

Fires have burned through almost a million acres between the two states so far in 2017, according to figures provided to Quartz (as of Sept. 7) from the Northwest Interagency Coordination Center. That’s up from the 2016 total of 513, 226 acres, though both 2015 and 2014 each saw more than a million acres affected by fires.

This summer’s wildfire season produced terrifying images. Smoke and ash even turned typically lush cities like Portland, Oregon and Seattle, Washington a hazy yellow reminiscent of Beijing’s signature smog (though weather patterns in the past few days improved air quality).
