Wildfire smoke headed towards northeastern Colorado

 As northerly winds spread across northeastern Colorado on Monday, wildfire smoke in Wyoming is poised to move in.  Expect particle pollution to increase throughout the region on Monday, with the areas in northeastern Colorado most impacted likely to be bounded by the Wyoming stateline to the north, the Nebraska and Kansas statelines to the east, Interstate 70 to the south, and the foothills to the west.  This will result in many towns/cities being impacted by worsening air quality on Monday, including Sterling, Ft. Morgan, Greeley, Ft. Collins, Boulder, and Denver.  Please visit CDPHE's wildfire smoke and health page for more information on how you can protect your health.

The biggest area of concern will be areas along the Interstate 25 urban corridor from Denver northward to Wyoming, along with the foothills just to the west of this stretch of Interstate 25.  This is where we could see longer duration, higher concentration smoke that could last from late Monday afternoon into Tuesday.  Advisories/Action Day Alerts may be required for this area, so please remain updated with the latest information on CDPHE's advisory webpage.
