Thousands of flights canceled as major winter storm moves across the US

“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.

President Donald Trump had approved emergency declarations for at least a dozen states by Saturday with more expected to come. 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 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 Gov. Mikie Sherrill said Saturday while announcing restrictions on commercial vehicle travel and a 35 mph (56 kph) 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 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 residents 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, said Mark Pierce, a spokesperson for the local sheriff’s office.

“We got limbs that are dragging the ground,” Pierce said. “These trees are just completely saturated with ice.”

Airplanes are grounded

About 13,000 flights were canceled Saturday and Sunday across the U.S., according to the flight tracking website FlightAware.

All Saturday flights were canceled 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 canceled 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 canceled.

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 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 Saturday, with 1,800 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 sweeping through the South, the storm was expected to move into the Northeast, dumping about 1 to 2 feet (30 to 60 centimeters) of snow from Washington through New York and Boston, 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 Saturday. “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 F (minus 40 C), meaning that frostbite could set in within 10 minutes. The minus 36 F (minus 38 C) 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 U.S. Immigration and Customs Enforcement to leave Minnesota on Saturday still faced an outdoor temperature of minus 6 degrees Fahrenheit (minus 21 Celsius).

Workers from The Orange Tent Project, a Chicago nonprofit 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 canceled. 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 canceled or rescheduled.

Schools superintendents in Philadelphia and Houston announced that schools would be closed Monday.

Some universities in the South canceled classes for Monday, including the University of North Carolina at Chapel Hill and the University of Mississippi’s main campus in Oxford.

Around the southeast, 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 2,000 miles 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 Center. “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.”
