At least 28 people have died as brutal Winter Storm Fern battered the US — including two teens in tragic sledding accidents, an elementary-school teacher who wandered from a bar, and six people on a private jet that crashed in Maine.

The grim toll also includes at least seven people in New York City, although their exact cause of death has not been released, and a man shoveling snow outside a Long Island church. 

The first reported US death was a 16-year-old girl who died when she and another girl were being towed on a sled in Texas by a 16-year-old boy driving a Jeep. The sled slammed into a curb and then collided with a tree, according to police in Frisco, just outside of Dallas.

The two girls were rushed to local hospitals, where one died from her injuries and the other remains in critical condition, cops said. The incident remains under investigation, and no arrests have been announced.

The girl died in the historic snowstorm that has now impacted more than 235 million Americans, according to the Dallas Morning News.

A 17-year-old boy also was killed in Arkansas in another sledding accident when he hit a tree while being pulled by an ATV, officials said.

Kansas second-grade teacher Rebecca Rauber, 28, perished, too, after leaving a bar on foot late Friday without her purse and in 3-degree temperatures. Her body was found Sunday covered in snow several hundred yards away from where she was last seen, and authorities believe she died from hypothermia.

Six people have also been confirmed dead after a private plane crashed and burst into flames just after taking off in Bangor, Maine, late Sunday, the Federal Aviation Administration confirmed Monday.

The jet is registered to a top Houston-based law firm, according to federal records.

The Bombardier Challenger 600 “crashed under unknown circumstances on departure” before it “came to rest inverted and caught on fire,” according to preliminary Federal Aviation Administration findings.

Audio recordings captured someone saying, “Let there be light” just before air traffic controllers reported having “a passenger aircraft upside down” roughly 45 seconds after it was cleared to take off.

Locally, seven people were found dead in New York City, with the sixth, a 52-year-old man, found Sunday at 96th Street and 34th Avenue in Queens, according to police.

At least some of those who died in the Big Apple had had interactions with the city’s shelter system in the past, according to Mayor Zohran Mamdani. 

“At this time, what we know is that a number of those seven New Yorkers who lost their lives had interactions with our shelter system in the past. It is still too early to share a broader diagnosis or a cause of death,” Mamdani said during a news conference Monday.

“However, as you’ve said, and I think as many New Yorkers know, this kind of cold, we haven’t seen this kind of cold for eight years, and it is debilitating,” Hizzoner added.

Another fatality was reported in Floral Park on Long Island, where a former New York Police Department officer, 60-year-old Roger McGovern, died while shoveling out a church, News 12 reported.

In Essex County, New Jersey, a 67-year-old man also died on Sunday after experiencing a medical episode while shoveling snow, according to NJ.com.

In Lehigh County, Pa., three people died while removing snow, the county coroner said. The three were between 60 and 84 years old.

In Massachusetts, a 51-year-old woman was killed when she and her husband were struck by a snowplow in a Massachusetts Bay Transportation Authority parking lot, according to NBC Boston.

The husband survived and is recovering in the hospital, authorities said. The plow driver remained at the scene and is cooperating with authorities.

“This is an unimaginable, horrific incident,” MBTA Transit Police Superintendent Richard Sullivan said. 

Another person was found dead from hypothermia outside of an Austin, Texas gas station, officials said.

An additional three deaths tied to the massive storm were reported in Tennessee and two in Louisiana, ABC News reported.

Outside of Chicago, a commuter train crashed into a snowplow Monday morning in Bartlett, Ill., sending the driver to the hospital in critical condition.

By Monday morning, about 700,000 Americans were still without power as temperatures remained below freezing. Tennessee, Texas, Mississippi and Louisiana were hit the hardest, according to poweroutage.us.

The Nashville Electric Service, the hardest-hit utility in the country, announced it will “double its workforce by midday today, with nearly 300 lineworkers deployed across our service area.”
