COPY-Midwest storms: Staff moves patients after hospital hit

CRESTON, IA (RNN) – A search effort is on after a possible tornado hit a hospital, according to a dispatcher with the Union County Sheriff's Department.

The storm that touched down was reported just before 9:30 p.m. eastern time in the community about an hour and a half southwest of Des Moines.

"We have been hit. We are triaging and moving patients," confirmed a spokeswoman at Greater Regional Medical Center.

No deaths or serious injuries have been reported.

Creston Mayor Warren Woods said that most of the city is without power.

The storm was part of a series of outbreaks that authorities have warned for almost two days could become potentially dangerous.  

Other large tornadoes touched down in the Midwest on Saturday evening in what officials believe could be one of the most serious outbreaks in U.S. history.

Most of those storms began in rural areas earlier, but they approached heavily populated areas later in the day.

About 50 tornadoes have been reported so far, and the threat of severe weather is expected to last until well into Sunday.

A wedge tornado – a large, wide storm that does not have a distinct point at the bottom because of its massive size – was reported near Wichita, KS, early Saturday evening. Wedge tornadoes are capable of causing significantly more damage.

Baseball-sized hail broke windows and ripped apart homes in northeast Nebraska. Hail also reportedly shattered windows and damaged vehicles in Petersburg, about 140 miles northwest of Omaha, and more tornadoes were spotted in Oklahoma.

The Storm Prediction Center, part of the National Weather Service, said the outbreak could be a "high-end, life-threatening event."

The National Weather Service's Wichita office used an experimental warning system that gave graphic terms to warn residents of potential harm. 

The destruction of the tornadoes was expected to be so widespread that on Friday the National Weather Service gave a more than 24-hour notice of the severe weather.

This is just the second time in U.S. history the National Weather Service has issued a severe storm notice more than a day in advance.

It happened once before in April 2006 when 100 tornadoes that swept across Tennessee killed 12 people and destroyed more than 1,000 homes.

More storms are possible in north Texas, Iowa, southeast South Dakota and southern Minnesota.
