(CNN) -- It was a menacing sight -- two powerful tornadoes swirling side by side through the countryside of northeastern Nebraska.
At one point, the twin twisters straddled a state highway.

"It was terribly wide," Marianne Pesotta told CNN affiliate KETV in the town of Pilger. "I drove east (to escape). I could see how bad it was. I had to get out of there."
Stanton County Sheriff Mike Unger said up to three-quarters of Pilger, a town of about 350 people, was destroyed Monday. The severe weather also caused damage in the towns of Wisner, Stanton and Pender.
All four communities are within about 40 miles (64 kilometers) of one another, about and hour and a half northwest of Omaha.
The National Weather Service also received unconfirmed tornado reports in Iowa, North Dakota and Wisconsin, where emergency workers were searching homes in the cities of Madison and Verona after possible wind damage there, according to police. There were no reports of injuries or deaths, said Tom Prochaska of the Madison police communication center.
The aftermath was almost too much to take for some like Marilyn Andersen, another Pilger resident.
"I've never been through this before," she told affiliate KMTVthrough tears. "It was an experience, and I don't want to go through it again."
Two deaths were reported. Unger said a 5-year-old was killed in Pilger, but he didn't say how. Another person died outside of town, he said.
Faith Regional Health Services in Norfolk said 16 people were critically injured in the severe weather.
Early into Tuesday morning, officials were assessing the damage, trying to determine how many were injured and how much damage was done.
"We're still digging people out," said Sanford Goshorn, the emergency manager in Stanton County, where Pilger and Stanton are located.
Wisner is in Cuming County, and Pender in Thurston County.
Nebraska Gov. Dave Heineman, who will tour the storm damage Tuesday, issued a state of emergency, putting the National Guard on standby to help if needed.
The state emergency management agency reported "severe damage" across the affected counties.
"They talk about war zones -- yes, this looks like a war zone," Goshorn said. "This looks like a war zone in Pilger."
