Gatlinburg, Sevier County (WVLT) - Two fires burning in the Smokies are contributing to the hazy conditions in Knoxville, those fires have already burned almost 900 acres.
Firefighters in the Smokies have their hands full and are keeping a close watch now that two new fires are burning.
After a lightning strike on Monday, a fire finally burned through near Cades Cove Wednesday.
Firefighters had it contained by noon Thursday.
Then, they discovered another near look rock on foothills parkway, about ten miles from Walland.
These, plus the 820 acre Buckshank fire that has been burning since May 20th, have firefighters keeping a close eye on any potential problems.
So should you be concerned if you're heading up here?
The National Park Service says the smoke and dust particles are adding to pollution already in the higher elevations, and if you have health conditions, you may need to take caution.
"People especially, if they have health concerns, need to be a little bit conservative about how high and how fast they hike. There are things we advise every year when we have things like this,” says Bob Miller from the National Park Service.
But the National Park Service says these fires don't affect people's use of the park.
Only four trails are closed out of 860 miles of trails, and all campgrounds, picnic areas and roads are still open.
