Forecasters are warning Britain will be hit by the Beast from the East part three as freezing Scandinavian winds sweep towards the country in the coming days.
A spokesman for Lancashire Council Council said: "When the bad weather strikes this winter, our fleet of gritters and snow ploughs will be working hard to keep Lancashire's roads moving.
"All priority routes in Central and South Lancs to be gritted this evening.
"We have weather predictions of ice with temperatures falling below zero. We will apply salt to all priority routes."
Priority routes only cover a third of the highway network and ice patches can develop on treated surfaces caused by water run-off from fields or other sources, a spokesman said.
