One week after a spring blizzard largely paralyzed the Black Hills and surrounding region, a second powerful storm again struck, closing roads, schools, businesses and government offices.

National Weather Service officials said that this week's version wasn't quite as powerful as last week's, but it is far more expansive.

A blizzard warning and winter storm warning that began early this morning and is scheduled to expire Tuesday, included most of South Dakota, with only the far southwest and southeast corners being spared.

Snowfall of 10 inches or more and winds to 40 mph were forecast in the warning area.

"This is one of those storms that's taking its time getting though the state," Gov. Mike Rounds said at midday Monday. "Western South Dakota is being impacted right how. We've got significant amounts of snow and high winds affecting most of West River South Dakota."

As of noon Monday, the National Weather Service reported 4-8 inches of snow in northwest South Dakota, 7-10 inches in the northern Black Hills and foothills, and 3-5 inches from Rapid City to Hermosa.

School closings blanketed the region, and most that weren't closed were either beginning late or letting out early.

No travel advisories were in effect for most U.S. and state highways in the region, and several cities, including Rapid City, put no travel advisories in place.

In Sturgis in the Northern Hills, officials said they would ticket and fine drivers who became stuck or standed in the rapidly deteriorating weather. In Rapid City, police said motorists seemed to be adhering to the advisories, noting that only a few motorists needed assistance throughout the morning.

Also on Monday morning, the Transportation Department closed Interstate 90 between Wall and the Wyoming border.

"The interstate right now literally just wasn't passable any more. We have a real tough time keeping the underpasses open. So rather than having people stuck in them, when Wyoming shut down their portion, we shut down our portion at the same time," Rounds On Monday morning, the Transportation Department closed Interstate 90 between Wall and the Wyoming border.

"The interstate right now literally just wasn't passable any more. We have a real tough time keeping the underpasses open. So rather than having people stuck in them, when Wyoming shut down their portion, we shut down our portion at the same time," said Rounds.

He said other interstate closings are likely as the storm moves east later Monday and overnight.

Meanwhile, closures were widespread.

Closures included YMCA child care, Pennington County Courts, Mount Rushmore National Memorial, Rapid City Area Chamber of Commerce and even Rapid City Regional Airport. Most of Rapid City Regional Health Care's non-emergency services were to be suspended by 1 p.m. today, with Rapid City Regional Hospital and Lead-Deadwood Regional Hospital being put on "Condition Snow."

Prairie Hills Transit was operating in Edgemont and Hot Springs in the Southern Hills but not in any other Hills' communities.

And the Eastside Band Concert originally scheduled for March 23 and rescheduled for March 30 has been cancelled. The concert will not be rescheduled. Refunds for advance ticket sales will be given to those returning the tickets at their school offices.

The storm, which rolled into the Hills between 3 a.m. and 5 a.m. Monday, wasn't expected to subside until some time Tuesday. By the team it leaves, it will be the Northern Hills that sees the most snow again. Twenty to 30 inches forecast at Deadwood and Lead.

Lead recorded 43 inches of snow in the March 23-24 storm and nearly 4 feet in a November storm.

For the year, the town has recorded 218 inches of snow this season. Deadwood has received 180 inches.

The National Weather Service's Jeff Johnson said the new storm will not be as powerful as the one a week ago but will still "carry a punch."

"This is still going to be a bad storm," he said. "We're in a real active part of the jet stream right now."
