Deadly storms across the US deliver tornadoes, snow and flooding (2024)

At least four people have died and over half a million homes are without power after a series of powerful winter storms swept through parts of the eastern US and Canada.

Strong winds flipped cars and knocked over homes in Florida, where several tornadoes were reported.

More than 1,300 flights in or out of the US were cancelled on Tuesday, according to data from FlightAware.

Vice-President Kamala Harris' plane had to be diverted due to weather.

A spokesperson for Mrs Harris said that "inclement weather" required her plane from Atlanta to land in Virginia rather than neighbouring Maryland on her way back to Washington DC.

As of Tuesday evening, more than 630,000 households in the eastern US, from Florida to New York State were without electricity.

Gov Ron DeSantis declared a state of emergency for 49 Florida counties, where storms have blown roofs off homes and knocked down power lines.

Twelve tornadoes were reported across Florida, Alabama and Georgia by early Tuesday, causing significant damage and, in some areas, prompting search and rescue operations.

More than 22 million people were under tornado watches.

In Houston County, Alabama, an 81-year-old woman was reportedly killed after a tornado ripped through the area, destroying mobile homes and RVs.

One person was killed and two others were critically injured in Claremont, North Carolina, officials said, after a powerful storm moved through a mobile home park.

A motorist died in Clayton County, Georgia, officials said, after a tree fell across a highway and crushed the driver's car.

And one man was also crushed to death by a toppled tree in Birmingham, Alabama, on Tuesday morning, the local station WVTM reported, citing local officials.

A resident of Panama City, Florida, who lives across from a home that was toppled by the wind said it sounded like a "freight train hitting a brick wall".

"That's how loud it was," he told CBS News, the BBC's US partner.

The storms also left roadways impassable in Panama City, ripped roofs off of buildings and brought hail the size of baseballs.

A curfew has been declared for the city's downtown area until 06:00EST (11:00GMT) on Wednesday morning.

"No one should be moving around in this area after dark," the Bay County Sheriff's Office posted on Facebook.

The National Weather Service (NWS) warned that more powerful storms are in store for the region and elsewhere in the eastern US.

In New Jersey, a coastal flood advisory is in effect until Wednesday. The state's governor Phil Murphy declared a state of emergency and warned residents not to "underestimate" the storm.

In New York State, Governor Kathy Hochul warned the storm could be "life threatening", especially as the expected rainfall would combine with the snow already blanketing the ground, bringing about potential flash-flooding.

Around 2,000 migrants living in a city tent shelter on an airfield in Brooklyn were evacuated by authorities to high school gymnasiums until the storms pass.

A ground stop was briefly issued at Chicago's O'Hare International Airport - one of the country's busiest - due to excessive snow and ice, the Federal Aviation Administration (FAA) said. A stop was also issued for Florida's Tampa International Airport due to a tornado warning.

Severe weather has also disrupted road travel in states like Nebraska and Kansas, where state patrol has responded to hundreds of weather-related incidents.

"Please stay home," a Kansas state trooper wrote on social media. "It's getting to the point where we will not be able to rescue you if you get stuck because we are having trouble getting around."

The NWS said it expects the extreme weather to slightly ease going into Wednesday, though snow showers are still possible in some of the already affected areas in the central US and the northeast.

Flood warnings issued by the NWS remained in effect on Wednesday morning from Louisiana to Maine, encompassing at least 15 states along the US Atlantic coast.
