(KMOV.com) -- For residents south of St. Louis, Thursday’s chief concern will be ice.
Crews in both Franklin and Jefferson Counties are expecting snow, then sleet, and finally freezing rain.
Fighting the freezing roadways will be a challenge especially because of the amount of rural, hilly roads in the area.
Festus and Hillsboro say their crews will start treating the roads once the weather moves in, using salt along with a sand mixture for traction.
Desoto started pre-treating roads around 9 p.m. Thursday night, keeping eight trucks on duty around the clock until the winter weather moves out.
The Jefferson County Public Works Department is sending crews out starting at 11 p.m. Thursday to pre-treat the roads in unincorporated Jefferson County.
“We’re dealing with sharp turns, and topography changes; high grades, Highs and lows. It’s not easy,” said Jefferson County Public Works Director Jason Jonas. “We’re not in the middle of Iowa here so it’s difficult but we have very experienced crews.”
Are officials say it’ll be a lot of hands on deck including chainsaws, and loaders to pick up big trees.
“If we have a heavy icing then you would have tree breakage you have trees down, then we’ll activate the brush crew,” said Eva Gadcke, Franklin County Highway Administrator. “And we’ll have them in.”
During the last ice storm, Franklin County officials say they had to close roads because of ice taking down trees.
