Smoke from more than 100 wildfires in Saskatchewan has drifted hundreds of miles south to the air above Colorado. That's prompted the state Department of Public Health and Environment to issue a smoke advisory for all of Colorado east of the Continental Divide through Wednesday morning.
CDPHE says the affected areas include Denver, Boulder, Fort Collins, Greeley, Colorado Springs, Pueblo, Trinidad, Lamar, Burlington, and Sterling.
Officials advise remaining indoors if smoke becomes thick in your neighborhood:
This is especially true for those with heart disease, respiratory illnesses, the very young, and the elderly. Consider limiting outdoor activity when moderate to heavy smoke is present. Consider relocating temporarily if smoke is present indoors and is making you ill. If visibility is less than 5 miles in smoke in your neighborhood, smoke has reached levels that are unhealthy.
The warning is set to expire Wednesday at 9 a.m.
