Harsh weather moved west on Monday as a polar vortex was expected to grip the Rockies and the northern Plains after winter storms pummeled the eastern US over the weekend, killing at least 10 people, including nine victims in Kentucky who died during flooding from heavy rains.

The National Weather Service warned of “life-threatening cold” into Tuesday, with temperatures in northeastern Montana predicted to dip as low as 45 degrees below zero (-42.7 degrees Celsius) with wind chills down to 60 below (-51 degrees Celsius).

Dangerously cold wind chill temperatures as low as 50 degrees below zero (minus 45.6) were expected in most of North Dakota, which remained under an “extreme cold warning” along with large swaths of South Dakota and Minnesota, according to the weather service.

Meteorologists said several states would experience the 10th and coldest polar vortex event this season. Weather forces in the Arctic are combining to push the chilly air that usually stays near the North Pole into the US and Europe.

Kentucky, Appalachia battered by flooding

Kentucky Gov. Andy Beshear announced Sunday that the death toll in his state had risen to nine and at least 1,000 people stranded by floods had to be rescued. President Donald Trump approved Kentucky's request for a disaster declaration, authorizing the Federal Emergency Management Agency to coordinate relief efforts throughout the state.

In Atlanta, a person was killed when a large tree fell on a home early Sunday, raising the overall death toll from harsh weather to 10.

Parts of Kentucky and Tennessee received up to 6 inches (15 centimeters) of rain, Bob Oravec, a senior forecaster with the National Weather Service, said Sunday.

Water submerged cars and buildings in Kentucky and mudslides blocked roads in Virginia over the weekend. Flood warnings extended throughout Tennessee and Arkansas.

In West Virginia, 13 southern counties were under a state of emergency for flooding and some areas were cut off to vehicle traffic Sunday. Several volunteer fire departments dealt with flooding in their own buildings while answering rescue and evacuation calls.

Rockies, Midwest, Northeast hit with snow storms

Ice and snow made road travel treacherous in large swaths of Michigan, which remained under a winter weather advisory until Monday afternoon. Michigan State Police reported 114 crashes Sunday around the Detroit area since snow started falling Saturday.

“Fortunately, most were one-car spin outs and there were no serious injuries,” Michigan State Police said on X.

Authorities in Colorado reported eight people were killed in fatal vehicle crashes since Valentine’s Day and warned drivers to be cautious as the weather made driving more difficult. The causes of the fatal crashes weren’t immediately known.

Also in Colorado, three state patrol cruisers that had pulled over along roadsides were struck by other vehicles, including one on Sunday where a trooper had stopped as officials prepared to close a road because of ice. In each case the troopers were out of their cruisers at the time and were uninjured.

Avalanche warnings were issued for numerous areas of the Rocky Mountains stretching from Colorado to Washington state, with the danger rated highest in Utah.

Part of Detroit is submerged in water after pipe burst

Parts of a southwest Detroit neighborhood are submerged after a nearly century-old water main burst early Monday.

The 54-inch (137-centimeter) transmission main was built in 1930 and has left several feet of water over streets, sidewalks and yards, according to the Great Lakes Water Authority.

Crews and contractors were in the area attempting to isolate the break. It was not clear what caused the main to burst, but temperatures late Sunday into Monday morning were well below zero degrees Fahrenheit (minus 17 degrees C).

No injuries have been reported. Firefighters used a ladder to help one person from the roof of a car in waist-deep water and a bulldozer was used to navigate a flooded street and help people leave a home, according to the fire department.

Mayor Mike Duggan says people impacted by the flooding can shelter in place if they have power and feel safe. Those who want to leave can call 911 and fire crews will help them from their homes and take them to a temporary shelter.

Avalanche warnings for Rockies and elsewhere

Avalanche warnings were issued for numerous areas of the Rocky Mountains stretching from Colorado to Washington state, with the danger rated highest in Utah.

The Mount Washington Avalanche Center issued an avalanche warning Monday for several places in the White Mountains — including Tuckerman Ravine, Gulf of Slides, Huntington Ravine, and Great Gulf — in the state of New Hampshire.

Two ice climbers were rescued in the White Mountains on Sunday after they triggered an avalanche and one of them became partially buried in the snow, the New Hampshire Fish and Game said in a statement.

Before Swedish slow TV hit “The Great Moose Migration” began airing Tuesday, Ulla Malmgren stocked up on coffee and prepared meals so she doesn't miss a moment of the 20-day, 24-hour event.

“Sleep? Forget it. I don’t sleep,” she said.

Malmgren, 62, isn't alone. The show, called “Den stora älgvandringen” in Swedish, and sometimes translated as “The Great Elk Trek” in English, began in 2019 with nearly a million people watching. In 2024, the production hit 9 million viewers on SVT Play, the streaming platform for national broadcaster SVT.

The livestream kicked off a week ahead of schedule due to warm weather and early moose movement. Malmgren was ready.

From now until May 4, the livestream's remote cameras will capture dozens of moose as they swim across the Ångerman River, some 300 kilometers (187 miles) northwest of Stockholm, in the annual spring migration toward summer grazing pastures.

Not much happens for hours at a time, and fans say that's the beauty of it.

“I feel relaxed, but at the same time I’m like, ‘Oh, there’s a moose. Oh, what if there’s a moose? I can’t go to the toilet!’” said William Garp Liljefors, 20, who has collected more than 150 moose plush toys since 2020.

Slow TV success “The Great Moose Migration” is part of a trend that began in 2009 with Norwegian public broadcaster NRK's minute-by-minute airing of a seven-hour train trip across the southern part of the country.

The slow TV style of programming has spread, with productions in the United Kingdom, China and elsewhere. The central Dutch city of Utrecht, for example, installed a “fish doorbell” on a river lock that lets livestream viewers alert authorities to fish being held up as they migrate to spawning grounds.

Annette Hill, a professor of media and communications at Jönköping University in Sweden, said slow TV has roots in reality television but lacks the staging and therefore feels more authentic for viewers. The productions allow the audience to relax and watch the journey unfold.

“It became, in a strange way, gripping because nothing catastrophic is happening, nothing spectacular is happening,” she said. “But something very beautiful is happening in that minute-by-minute moment.”

As an expert and a fan of “The Great Moose Migration,” Hill said the livestream helps her slow down her day by following the natural rhythms of spring.

“This is definitely a moment to have a calm, atmospheric setting in my own home, and I really appreciate it,” she said.

The calming effect extends to the crew, according to Johan Erhag, SVT's project manager for “The Great Moose Migration.”

“Everyone who works with it goes down in their normal stress,” he said.

The moose have walked the route for thousands of years, making it easy for the crew to know where to lay some 20,000 meters (almost 12 miles) of cable and position 26 remote cameras and seven night cameras. A drone is also used.

The crew of up to 15 people works out of SVT’s control room in Umeå, producing the show at a distance to avoid interfering with the migration.

SVT won't say how much the production costs, but Erhag said it's cheap when accounting for the 506 hours of footage aired last year.

Erhag said Swedes have always been fascinated by the roughly 300,000 moose roaming in their woods. The Scandinavian country's largest animal is known as “King of the Forest.” A bull moose can reach 210 centimeters (6 feet 10 inches) at shoulder height and weigh 450 kilograms (992 pounds).

Despite their size, the herbivores are typically shy and solitary.

“We actually don’t see it very often. You often see it when you’re out driving maybe once or twice in your life,” Erhag said. “I think that’s one thing why it has been so, so popular. And then you bring in the nature to everyone’s living room.”

Hanna Sandberg, 36, first began watching the show in 2019, though she didn't spot any moose. She tuned in the following year, finally saw some and got hooked.

“You can watch them and be a part of their natural habitat in a way that you could never be otherwise,” she said.

After hours of showing an empty forest, a camera captures footage of a moose approaching the riverbank. Suddenly, slow TV turns urgent.

The push alert hits SVT's app — “Första älgarna i bild!” which translates to “First moose on camera!” — as viewers worldwide tune in. The livestream's chat explodes as commenters type encouragement for the animal, now making its way into the water.

“I would actually like to be a little fly on the wall in every household that watches the moose migration. Because I think there are about a million people saying about the same thing: ‘Go on! Yes, you can do it!’” Malmgren said.

Mega-fans like Malmgren, who is in a Facebook group of 76,000-plus viewers, are committed to watching as many hours as possible.

“I was late to school because I saw moose and my teacher was like, ‘What, you saw moose in the city?’ And I was like, ‘No, it’s on the TV,’” Garp Liljefors said.

Malmgren said friends and family have learned not to bother her when the moose are on the move.

“When someone asks me, ‘What are you doing? Oh, never mind, it’s the great migration,’” she said. “They know.”
