Snow-swept interstates in the Upper Midwest are slowly starting to reopen following a massive late-winter storm that has also caused flooding in several states.

Interstate 29 between Fargo and the Canadian border in eastern North Dakota is now open to travel. KFGO radio reports that a snow plow driver cleared a path on Interstate 94 in southeastern North Dakota on Thursday for an ambulance that needed to get a patient to a hospital.

State government in South Dakota is also returning to normal as travel conditions improve. Most offices have been closed for the last two days because of bad weather and treacherous travel conditions.

Heavy rain falling atop deeply frozen ground has prompted evacuations along swollen rivers in Wisconsin, Nebraska, South Dakota and Iowa. Meteorologists say the flooding is likely to persist into the weekend in states where frozen ground is preventing rain and snowmelt from soaking into the soil.

Snow, rain and powerful winds are sweeping across the Upper Midwest.

No travel is advised Friday morning in areas near Fargo, North Dakota, as heavy snow and poor visibility prompted the closure of two interstates.

In South Dakota, schools in Rapid City are closed as authorities dig out from a blizzard. Flooding on the other side of the state prompted officials in Sioux Falls to go door-to-door and evacuate residents from homes.

Flooding has also made several highways in Wisconsin unpassable. In Fond du Lac, rescuers had to move residents to higher ground after flooding on the Fond du Lac River.

Authorities say a tornado swept through mid-Michigan, damaging homes and knocking out power to thousands late Thursday. State police said first-responders say at least 21 homes were damaged, though no injuries have been reported.

A late-winter storm system continues its trek across the Midwest. It will send rain and snow into Minnesota and Illinois on Friday.

The storm left quickly rising floods in its wake in parts of eastern Nebraska and Iowa that saw residents evacuated from their homes, roads washed out in communities, and farmers worried all the water would drown livestock.

The National Weather Service says the system is expected to move into southern Minnesota and parts of Illinois, including Chicago, on Friday, with rain later turning to snow. But meteorologist Paul Fajman in Omaha says the effects aren't expected to be as bad as what was seen farther west and south.

A blizzard crippled parts of Wyoming, Colorado and western Nebraska on Wednesday.
