Judging from these maps, the air quality in southern British Columbia and the U.S. Northwest looks particularly rotten today. (“Rotten” is not a term I’ve seen NOAA use to describe air quality, but it seems appropriate here.)
Locations in Washington and Idaho had the distinction of taking four of the top five positions on the forecast for the “highest 5”, AKA worst air, in the United States today.
