Travel alert: Wildfire smoke impacts some of America's most popular national parks

As millions of Americans flock to national parks this summer, the smoke could create hazy skies and unhealthy air quality.

SPOKANE, Wash. - As wildfires rage in Spokane, Washington, you may be wondering where all that wildfire smoke will end up.

By Thursday night, wildfire smoke will have engulfed cities and towns in many states, including Washington, Oregon, Idaho, Nevada, Utah, Wyoming and Montana. Portions of Colorado are also included in Air Quality Alerts, including the city of Denver, for increased amounts of wildfire smoke.

HERE'S HOW THE WILDFIRES IN SPOKANE COMPARE WITH THE MOST DESTRUCTIVE IN US HISTORY

The current Air Quality Index has these states at moderate to unhealthy for sensitive groups, and that will likely continue over the next few days.

There are currently three major wildfires burning around the Spokane area, with a combined footprint of over 10,000 acres. Tens of thousands of residents were evacuated over the weekend and at least 700 structures have been destroyed as a result of the wildfires.

You may remember the recent Canadian wildfires which caused hazy skies in much of the Northeast last month. The smoke returns, but this time, on the other side of the country.
