DENVER (CBS4) – There’s a lot of prep work to be done to keep drivers moving through the metro area before that snow begins to fall.

Officials from Denver Public Works say the first plows will hit the road as soon as there’s accumulation on major Denver streets. Seventy trucks in total will be plowing the roads in preparation for the big storm.

“We are expecting the streets to freeze sometime tonight, which means the morning commute will be slick, icy and snow packed,” Emily Williams with Denver Public Works said. “We will be out there all night long but we want to remind people to plan ahead for your drive in to work.”
