WHITESBURG, Ky. (WYMT) - Several acres have burned in Letcher county after a forest fire began last night near Whitesburg, and weather conditions may be partly to blame.

Forest rangers got the first call about the fire around 7 p.m. Wednesday. Fire fighters worked late into the night, establishing containment lines and burning out a perimeter.

"This morning we came back to check what portions did burn out last night and make sure nothing had fell across the containment line to make the fire spread," said ranger Robert Keith.

Forestry officials have been responding to several forest fires in recent days. They say the low humidity has been helping the fires spread.

"When it gets down into the high 20s, mid 20s, is when it's usually normal for us, but sometimes it'll go lower and we'll have a lot worse fires out of that," said Keith.

In all some 28 acres have burned in Letcher county, however forestry officials say the blaze has been contained, at least for now.

"It is contained. We're just watching it right now, making sure nothing comes over the containment lines, but it's almost completely burned in," Keith said.

Officials say they are looking into what may have sparked the fire, but they do suspect arson.
