The Colorado Department of Public Health and Environment issued an Air Quality Health Advisory for Colorado.
The counties include Sedgwick, Logan, Larimer, Weld, Morgan, Boulder, Broomfield, Washington, Adams, Denver, Arapahoe, Jefferson, Douglas, Elbert, Kit Carson, Lincoln, Cheyenne, El Paso and Phillips Counties.
CDPHE expects that smoke from wildfires in Canada will impact local air quality through the afternoon.
A record-breaking heatwave in western Canada has fueled 90 wildfires.
“This is a very unusual pattern. We often don’t see these types of patterns set up this early in the year. We see these patterns in the summer,” said Terri Lang, a warning preparedness meteorologist for Environment and Climate Change Canada told NBC News.
CDPHE recommends that people with heart disease, respiratory illness, the very young and elderly limit outdoor activity when moderate to heavy smoke is present.
The warning also states that if visibility is less than 5 miles in your neighborhood, "smoke has reached levels that are unhealthy" and you should consider relocating if smoke enters your indoor space and is making you feel ill.
