Environment Canada is looking into reports that a tornado that hit Manitoba on Monday stayed on the ground for an “incredible” three hours.

"We generally don't see them last that long," Environment Canada meteorologist Terri Lang told The Canadian Press.

In fact, twisters normally touch down for just a few minutes.

Lang said workers are assessing the damage to determine the strength of the tornado, which travelled approximately 100 kilometres, and appears to have struck hardest near the town of Virden.

Damage reported so far includes toppled grain bins, torn up asphalt, damaged roofs and downed power lines.

Lang said the storm didn’t hit any towns or cities, and there were no injuries reported.

Fred Raynor, a farmer near the town of Tilston, said his two grandchildren and other family members took cover in a cellar as the storm approached. He watched from upstairs.

"There were chunks of trees and debris just flying everywhere. Some of it was going clockwise, some of it was going counter-clockwise, all at once,” he said.

Raynor said trees were uprooted and fell on the home’s roof.

There were also reports of rotating wall clouds and funnel clouds in southeastern Saskatchewan on Monday.

Saskatchewan had tornado warnings lifted by 11 p.m. and Manitoba had the warnings lifted by 12:30 a.m. Central Time.

Regina, meanwhile, was deluged with 73 millimetres of rain Monday, which caused some flash flooding in city streets.

Several members of storm-chasing groups tweeted videos and pictures of the violent storm.
