MESA COUNTY, Colo. (KKCO/KJCT)-- It wasn't hard to see the smoke covering up the Bookcliffs or the Grand Mesa on Monday. It created a hazy day in the Grand Valley.
"We have those westerly winds overhead and that's bringing that smoke into our area,” said Megan Stackhouse, a meteorologist with the National Weather Service.
Stackhouse said the smoke was coming from The Trail Mountain Wildfire, burning southwest of Price, Utah. More than 2,000 acres have burned.
There was enough smoke to prompt Mesa County Public Health to issue a smoke advisory which means the air outside is not the best to breathe.
"When we're in a smoke advisory you want to make sure you're not exercising outside,” said Katie Nelson, a spokesperson with Mesa County Public Health.
Someone can experience a number of symptoms if they were to exercise outside during a smoke advisory.
"Shortness of breath, coughing, that sort of thing,” said Nelson.
Nelson adds people won’t want that smoky air inside their house.
"You don't want your swamp cooler running because that pulls in air from the outside,” said Nelson.
With the drought Colorado is in, the smoke probably won't be the only time it covers up the mountains.
"When we get the right wind set up and we can get smoke from the wildfires across the area,” said Stackhouse. "We're expecting the smoke to stick around through the evening and first part of tomorrow and then the flow shifts to the southwest.”
This should push the smoke to the northeast.
