The dry weather is making it difficult for forestry officials trying to fight several wildfires.
An 80 acre fire in the Little Bull Creek area of Knox County is one of them.
Forestry officials say it's one of 11 fires burning in the southeastern forestry district.
They say only three of the fires are contained, but at last check, their efforts have prevented any fires from reaching homes.
Firefighters in Rockcastle County are working to make sure a fire there doesn't spread.
Early Thursday morning, the fire could be seen from the northbound lanes of I-75.
Firefighters were first called to it Wednesday afternoon.
They say no homes are in danger.
