FALLS, S.D. (AP) – A strong spring storm has made travel hazardous in much of South Dakota, shutting down schools, delaying some local elections and hampering construction projects.

The National Weather Service has issued various storm advisories, watches and warnings for the state. Forecasters say the storm moving across the Rocky Mountains and Greats Plains packs up to 20 inches of snow, sleet, freezing rain and strong winds.

The storm comes a day after heavy snow created bad travel conditions in southwest North Dakota, leading to numerous accidents. An oil tanker crashed near South Heart and spilled what authorities called a minimal amount of oil.
