ST. LOUIS, Mo. (KMOV.com) -

MoDOT said it will not be pretreating the roads ahead of a storm system expected to drop snow on the St. Louis area late Wednesday into Thursday.

2-3 inches of snow is expected to fall in the St. Louis area late Wednesday night into Thursday morning. The timing is expected to cause problems during the morning commute.

Tom Blair of MoDOT said crews are ready to go, but added there will be no pretreatment of the roads for several reasons:

  • It is too cold for some of the pretreatment to work.
  • If salt is down before the snow, it will be pushed away by traffic before the snow hits.
  • MoDOT believes the pretreatment will cause the initial snow to stick.
  • Because the snow is expected to dry, MoDOT wants some of it to blow off the road before plows come out

Once the snow starts falling, MoDOT said it will treat the roads and have plows out.

Blair said all crews in the St. Louis area will be out by 10:00 p.m.

The agency is urging anyone who does not have to travel during the overnight hours or during morning rush hour to stay home.

Both IDOT and St. Louis City said they are pretreating the roads. IDOT told News 4 putting down brine treatment before it snows breaks the bond between the snow and pavement.
