(KMOV.com) -- The Missouri Department of Transportation had a busy Sunday with several inches of snow being dumped in the St. Louis area. But it's only going to get worse as the agency says sub-zero temperatures expected on Monday will render some chemical treatments ineffective.

MoDOT says the liquid salt trucks spray out on the roads won’t work as well as it normally does when the temperature fall below 25 degrees.

Normally, a pound of the liquid salt can melt 45 pounds of ice, but MoDOT says that number drops to just 10 pounds of ice when the temperatures fall.

St. Louis Streets Department Director Todd Waeltermann says the agency deployed 70 plows to treat the St. Louis roadways. 

"We're going to have a long road ahead of us, and we'll be out there all night," he said. 

The winter storm that hit this weekend is expected to bring temperatures below zero come Monday. That will have an adverse affect on the road treatments.

MoDOT warns drivers that despite their best efforts to treat the roads, they will still be dicey drivers should use caution.
