Des Moines, IA (northwestiowanow.com) — Iowans are warned our sidewalks and roads may be dangerously icy this afternoon and tonight as a winter storm front moves across the state, bringing the potential for freezing rain.

National Weather Service Meteorologist Jim Lee says 64 Iowa counties are under a Winter Weather Advisory from noon until 9 o’clock tonight.

The advisory covers about two-thirds of Iowa, roughly from Highway 20 south. Lee says Iowans need to be prepared for a thin layer of ice and slick conditions later today.

The state DOT offers an updated road conditions website that shows where icy roads are located at 511ia.org.
