Haze covers parts of Snohomish County after Fourth of July fireworks

EVERETT — Air quality levels in parts of Snohomish County were at unhealthy levels Wednesday as the region bore the brunt of leftover firework smoke from the Fourth of July.

The haze in the air was also a result of a “handful” of local fires, according to the National Weather Service in Seattle.

In the morning, some cities in the county exceeded 150 on the Air Quality Index.

By noon, both Everett and Marysville were at an air quality level that was “unhealthy for sensitive groups,” with an Air Quality Index dropping slightly to 130.
