A brutal winter storm smacked the coastal U.S. southeast with a rare blast of snow and ice on Wednesday, hitting parts of Florida, Georgia and South Carolina with their heaviest snowfall in nearly three decades.

Forecasters warned that the same system could soon strengthen into a “bomb cyclone” as it rolls up the East Coast, bringing hurricane-force winds, coastal flooding and up to a foot of snow.

At least 17 deaths were blamed on dangerously cold temperatures that for days have gripped wide swaths of the U.S. from Texas to New England.

A winter storm warning extended from the Gulf Coast of Florida’s “Big Bend” region all the way up the Atlantic coast. Forecasters said hurricane-force winds blowing offshore on Thursday could generate seven-metre seas.

Schools in the Southeast called off classes just months after being shut down because of hurricane threats, and police urged drivers to stay off the roads in a region little accustomed to the kind of winter woes common to the U.S. Northeast.

In Savannah, snow blanketed the city’s lush downtown squares and collected on branches of burly oaks for the first time in nearly eight years. William Shaw, a Savannah native, used baby steps to shuffle along a frozen road from his home to the post office.

“It almost seems the town is deserted just like in the last hurricane,” said Shaw, 65. “There’s no one on the street. It’s got a little eerie feeling.”

Dump trucks spread sand on major streets in Savannah ahead of the storm and police closed several bridges, overpasses and a major causeway because of ice.

‘Enjoy it while it is here’

By the time the morning’s dreary sleet and rain turned to fluffy snow, Savannah came out to play. Families with children flocked to Forsyth Park near the downtown historic district for snowball fights. The National Weather Service recorded 3 centimetres of snow — Savannah’s first measurable snowfall since February 2010 and the first that exceeded 2.5 centimetres in 28 years.

Across the Georgia-South Carolina line in Charleston, the weather service reported 12.7 centimetres as the snow was winding down at 5 p.m. That’s the most snowfall in Charleston since December 1989, and plenty for Chris Monoc’s sons, ages 4 and 2, to go sledding outside their home near the city’s iconic Ravenel Bridge.

“They probably will be teenagers the next time something like this happens, and that’s kind of sad,” Monoc said. “But we’ll enjoy it while it is here.”

Airports shut down in Savannah, Charleston and elsewhere as airlines cancelled 500 flights Wednesday, and at least 1,700 more were cancelled on Thursday. Interstate 95 was nearly an icy parking lot for almost all of its 322 kilometres in South Carolina. Troopers couldn’t keep up with the number of reported wrecks which numbered in the hundreds.

In Tallahassee, Fla., Michigan transplant Laura Donaven built a snowman 15 centimetres tall. The city tweeted that snow fell there for the first time in 28 years.

“I made a snowball and threw it at my dad,” said Donaven, a 41-year-old hair salon owner.

‘Bomb cyclone’

The weather service said the winter storm will probably intensify into a “bomb cyclone” that could dump more than 8 inches 20 centimetres of snow on the Boston area on Thursday and at least half a foot 15 centimetres of snow in the New York City region.

Authorities in Eastern Canada were also bracing for the storm. Nova Scotia Power was preparing to deal with potential outages and many schools across the province had cancelled Thursday classes. Meanwhile Enviroinment Canada issued a winter storm warning for all of neighbouring New Brunswick.

A storm is a bomb, or bombogensis, when it drops 24 millibars of pressure in 24 hours. This storm looks like it will intensify at twice that rate, said Bob Oravec, lead forecaster at the National Weather Service’s Weather Prediction Center.

Mississippi’s largest city said record cold is breaking water mains, leaving some customers with little or no water flow.

Jackson city spokesperson Kai Williams said Wednesday evening that the city knew of 37 separate water main breaks that it attributed to cold. The city has declared an emergency and is hiring outside contractors to help repair water main breaks.

Blizzard warnings were issued from Rhode Island to Maine. Oravec said he expects they could be extended as far south as parts of New York.

“It’s sort of akin to a hurricane travelling up the coast,” says Ryan Maue, a meteorologist at the private firm Weather.US.

‘This is the coldest I’ve been in probably 50 years.’

Georgia Gov. Nathan Deal declared a state of emergency through Friday for 28 counties. School systems on the Alabama coast waived uniform requirements so students could bundle up.

Florida’s largest theme parks announced that water attractions such as Disney’s Typhoon Lagoon, Universal Orlando’s Volcano Bay and SeaWorld’s Aquatica were closed. Temperatures were running well below normal for this time of year, and the lows are expected to hover right around freezing.

Bitter cold snap

In Prairieville, La., Valerie Anne Broussard struggled overnight to keep warm in a house that is being rebuilt after the 2016 floods that hit the small community southeast of Baton Rouge.

“It’s like a camping trip that I didn’t sign up for,” said Broussard, who’s been huddling with her 8-year-old daughter, newborn baby and boyfriend in a bedroom warmed by space heaters.

Making the most of the South’s bitter cold snap, the North Carolina Zoo in Asheboro offered discounted tickets for those willing to brave the cold to see polar bears frolic in their kind of weather, along with Arctic foxes and elk. African elephants, lions and gorillas were sheltered out of public view.

As the cold pushed farther northward, Jerry Gorans found himself stunned by the frigid temperatures as he walked along the waterfront City Dock of Annapolis, Maryland, where birds stood still on icy water.

“This is the coldest I’ve been in probably 50 years,” said Gorans, who lives in Fresno, Calif., and was visiting his wife’s family in Maryland. “I mean, this is freezing cold. My feet hurt, my ears hurt.”
