(Near Hartford - WBIR) On Sunday, fire crews hope to put an end to a blaze that's burned hundreds of acres in an East Tennessee forest.

The Halls Top fire has so far burned 340 acres in the Cherokee National Forest in Cocke County.

The United States Forest Service said it started Saturday night. Right now, it is unsure as to how the fire started.

On Thursday, rain slowed the Halls Top fire down.

"There was one home that was mildly threatened and we got a liner around that the night we were working on it," said Unaka District Ranger Terry Bowerman.

Crews on the scene are using bulldozers to plow bare lines into the Earth Saturday. Those lines will make a perimeter for the US Forest Service's controlled burn Sunday.

"On Halls Top, we have a lot of heavy fuels, which means it's the bigger trees that have fallen down, dead pines from the beatle kills years ago and those will hold heat and fire," said Bowerman. "And, what we're concerned about is that we get a good line around it and get all the remaining fuel around, those heavy fuels burned, so there really is anything to burn and it can't spread larger.

Now, a fire this time of year is not uncommon.

This is actually wildfire season in Tennessee.

"We've had some fires," said Tennessee we've been very fortunate we haven't had more," said Nathan Waters, an assistant district forester for the state of Tennessee.

He said East Tennessee has been lucky considering the dry weather and low humidity that has been in the region as of late.

However, he said for the entire season, the fire danger has been about average.

"And, we still urge people to be careful," he said. "We're still issuing permits in most counties in East Tennessee."

Waters says burn away from forests. He added it also important to have a water hose nearby.Waters added that burn permits are still available in most East Tennessee counties.

Sunday's controlled burn will bump the fire up to near 850 acres, before it finally burns out.
