(CNN/AP) - This is the last weekend of winter 2019, and it’s making a grand exit.
More than 100 million people are under a watch, warning or advisory as the storm heads toward Canada.
Authorities say four tornadoes touched down in mid-Michigan during a fast-moving storm that swept across the state.
Homes were reported damaged, while power was knocked out to thousands of utility customers. No injuries have been reported, however.
Lower Michigan also saw severe thunderstorm warnings, watches, flooding, high winds and hail as a late-winter storm system trekked across the Midwest.
A bomb cyclone is when pressure drops at least 24-millibars within a 24-hour period.
The wrath of the bomb cyclone was seen and felt in Omaha, Nebraska, where the Mormon Canal Bridge washed out.
President Donald Trump said he spoke to Nebraska Gov. Pete Ricketts, and praised first responders and emergency response teams for doing “a great job dealing” with flooding, high winds and road closures.
Trump tweeted Friday that the people of Nebraska and across the Midwest, especially farmers and ranchers, are feeling the impacts from severe weather.
Thousands of people have been urged to evacuate along eastern Nebraska rivers as the massive late-winter storm system has pushed streams and rivers out of their banks throughout the Midwest.
Some residents in nearly 30 communities along the Missouri, Platte and Elkhorn rivers have been asked to evacuate.
In Lowell, IN, heavy winds knocked down power lines and 40-foot-tall pines.
“I don’t know where that tree came from because it wasn’t one of these. I don’t know,” said Madonna Snyder of the tree that fell on her house.
"You could hear it run through there. It was real loud, like a train," she said.
Severe weather and flooding also impacted the Evansville, IN, area, according to WFIE.
The heavy rains from the bomb cyclone caused major flooding in Missouri and Wisconsin, as well.
“We all of a sudden heard our washer and drier start buzzing and the water started rising in the basement,” one Fond Du Lac, WI, resident said.
Wisconsin Gov. Tony Evers has declared a state of emergency for much of the state as heavy rain and melting snow flood roads, fields and communities. And in Iowa, Gov. Kim Reynolds issued a disaster declaration as dozens of residents had to be rescued from floodwaters.
Some areas saw a lot of snow. Nearly four feet fell in southern Colorado.
The bomb cyclone is forecast to move east and then north to Canada, but its aftermath won't fade away anytime soon.
“With this melting snow and high temperatures, it’s really gonna bring the rivers up. We’ll be dealing with this for a while. We’ll be patient and do the best we can,” said Dennis Yoder with the Minnesota Department of Transportation’s highway maintenance.
