Oklahoma City: Thousands of flights across the United States were cancelled on Sunday (Monday AEDT) as a massive storm dumped snow and freezing rain from the southern states up through New England.
The storm brought frigid temperatures and treacherous roads across a 3,500-kilometre stretch, including New York and Washington DC.
Ice and snowfall are expected to continue through Monday, followed by dangerously low temperatures, causing “dangerous travel and infrastructure impacts” to linger for several days, the National Weather Service said.
Heavy snow was forecast from the Ohio Valley to the Northeast, while “catastrophic ice accumulation” threatened from the Lower Mississippi Valley to the Mid-Atlantic and Southeast.
“It is a unique storm in the sense that it is so widespread,” weather service meteorologist Allison Santorelli said in a phone interview.
More than 10,000 flights – many of them in New York and Washington DC – had already been cancelled on Sunday and another 8,000 have been delayed, according to the flight tracker flightaware.com.
As of Sunday morning, about 213 million people were under some sort of winter weather warning, she said. The number of customers without power was approaching 800,000, according to poweroutage.us, and the number was rising.
“The snow and the ice will be very, very slow to melt and won’t be going away anytime soon, and that’s going to hinder any recovery efforts,” said Allison Santorelli, a meteorologist with the National Weather Service.
US President Donald Trump had approved emergency declarations for at least a dozen states by Saturday, with more expected. The Federal Emergency Management Agency pre-positioned commodities, staff and search and rescue teams in numerous states, Homeland Security Secretary Kristi Noem said.
“We just ask that everyone would be smart – stay home if possible,” Noem said.
As crews in some southern states began working to restore downed power lines on Saturday, officials in some eastern states issued final warnings to residents.
“We are expecting a storm the likes of which we haven’t seen in years,” New Jersey Governor Mikie Sherrill said on Saturday while announcing restrictions on commercial vehicle travel and a 56km/h speed limit on highways. She added: “It’s a good weekend to stay indoors.”
Power outages hit Louisiana and Texas
Forecasters say the damage, especially in areas pounded by ice, could rival that of a hurricane.
Around 120,000 power outages were reported in the path of the winter storm on Saturday, including about 50,000 each in Texas and Louisiana, according to poweroutage.us.
In Shelby County, Texas, near the Louisiana border, ice weighed down on pine trees and caused branches to snap, downing power lines. About a third of the county’s 16,000 electric customers lost power on Saturday.
“We have hundreds of trees down and a lot of limbs in the road,” Shelby County Commissioner Stevie Smith said from his pickup truck. “I’ve got my crew out clearing roads as fast as we can. It’s a lot to deal with right now.”
There were reports of vehicles hitting fallen trees and trees falling onto houses in DeSoto Parish, Louisiana, where more than half of all electric customers lost power.
“We got limbs that are dragging the ground,” said Mark Pierce, a spokesperson for the local sheriff’s office. “These trees are just completely saturated with ice.”
Planes are grounded
About 13,000 flights were cancelled on Saturday and Sunday across the US, according to the flight tracking website FlightAware. Sunday’s cancellations, which are still growing, are already the most on any single day since the coronavirus pandemic, according to aviation analytics firm Cirium.
All Saturday flights were cancelled at Will Rogers International Airport in Oklahoma City, and all Sunday morning flights also were called off, as officials aimed to restart service Sunday afternoon at Oklahoma’s biggest airport.
Dallas-Fort Worth International Airport, a major hub, saw more than 700 departing flights cancelled on Saturday and nearly as many arriving flights called off. Disruptions were also piling up at airports in Chicago, Atlanta, Nashville, and Charlotte, North Carolina.
By late Saturday afternoon, nearly all departing flights scheduled to leave Ronald Reagan Washington National Airport on Sunday had already been cancelled.
Bracing for the biggest ice storm in a decade
Officials in Georgia advised people in the state’s northern regions to get off the roads by sundown on Saturday and be prepared to stay put for at least 48 hours.
Will Lanxton, the senior state meteorologist, said Georgia could get “perhaps the biggest ice storm we have expected in more than a decade” followed by unusually cold temperatures.
“Ice is a whole different ballgame than snow,” Lanxton said. “Ice, you can’t do anything with. You can’t drive on it. It’s much more likely to bring down power lines and trees.”
Crews began treating highways with brine after midnight on Saturday (Sunday AEDT), with 1800 workers on 12-hour shifts, Georgia Department of Transportation Commissioner Russell McMurry said.
“We’re going to do what we can to keep the ice from sticking to the roads,” McMurry said. “This is going to be a challenge.”
After earlier putting 500 National Guard members on standby, Georgia Governor Brian Kemp announced that he was deploying 120 of them to north-east Georgia “to further strengthen our response in the hardest-hit areas”.
After sweeping through the South, the storm was expected to move into the Northeast, dumping snow exceeding 30 centimetres, the weather service predicted.
“Please, if you can avoid it, do not drive, do not travel, do not do anything that can potentially place you or your loved ones in danger,” New York City Mayor Zohran Mamdani said. “Instead, I urge every New Yorker who can to put a warm sweater on, turn on the TV, watch Mission Impossible for the 10th time, above all to stay inside.”
Frigid temperatures affect the Midwest and North
The Midwest saw windchills as low as minus 40 degrees Celsius, meaning that frostbite could set in within 10 minutes. The minus 38C reading in Rhinelander, Wisconsin, on Saturday morning was the coldest in almost 30 years.
In Minneapolis, the worst of an extreme cold wave was over, but protesters calling for US Immigration and Customs Enforcement to leave Minnesota on Saturday still faced an outdoor temperature of minus 21C.
Workers from The Orange Tent Project, a Chicago non-profit that provides cold-weather tents and other supplies to unhoused individuals throughout the city, went out to check on those who did not or could not seek shelter.
“Seeing the forecasted weather, I knew we had to come out and do this today,” CEO Morgan McLuckie said.
Mardi Gras and classes cancelled. Opry performs without audience
Churches moved Sunday services online, and the Grand Ole Opry in Nashville, Tennessee, decided to hold its Saturday-night radio performance without fans. Mardi Gras parades in Louisiana were cancelled or rescheduled.
Schools superintendents in Philadelphia and Houston announced that schools would be closed on Monday.
Some universities in the South cancelled classes for Monday, including the University of North Carolina at Chapel Hill and the University of Mississippi’s main campus in Oxford.
Around the south-east, people used the cancellations to have some fun. On a hill outside the Capitol building in Nashville, adult sledders on green discs and inflatable pool animals giggled with joy as they slid in the snow.
Weather forecasters said the winter storm was unusual.
“I think there are two parts of this storm that make it unique. One is just a broad expanse of spatial coverage of this event … You’ve got 2000 miles [3218km] of country that’s being impacted by the storm with snow, sleet, and freezing rain,” said Josh Weiss, a meteorologist at NOAA’s Weather Prediction Centre. “The other part of this storm that’s really impressive is what’s going to happen right afterward. We’re looking at extreme cold, record cold.”
