Killer tornadoes in the US Southeast and historic sub-zero cold as far south as Texas were blamed on Tuesday for seven deaths and massive power outages that cancelled Covid-19 inoculations and threatened to disrupt vaccine supplies.

Treacherous weather will maintain its grip on many parts of the US from Tuesday through Friday, with up to 4 inches of snow and freezing rain expected from the southern Plains into the Northeast, forecasters said.

“We're calling it Storm System No. 2, with very similar placement to the previous storm,” said meteorologist Lara Pagano of the National Weather Service's Weather Prediction Center in College Park, Maryland. She was referring to a system that blasted the nation through the long Presidents Day holiday weekend, dumping snow and ice from Ohio to the Rio Grande.

An Artic air mass that descended over much of the country pushed temperatures to historic lows on Tuesday, Pagano said. In Lincoln, Nebraska, a reading of minus 31 degrees Fahrenheit (minus 35 °C) on Tuesday shattered a record set in 1978 of minus 18F (minus 27C).

In typically toasty Dallas-Fort Worth, minus 1F (minus 17C) broke a record set in 1903 of 12F (minus 11C).

“That's what people are waking up to this morning: It's just dangerous,” Pagano said.

Crippled by more than 4.4 million power outages in Texas alone, authorities shut down inoculation sites and scrambled to use 8,400 vaccines that require sub-zero refrigeration before they spoiled after a backup generator failed, Harris County Judge Lina Hidalgo said. Doses were rushed to area hospitals and Rice University to be injected into the arms of people already at those locations and who didn't have to travel on slick roads.

Icy roads were blamed for one of the four deaths tied to the bitter cold. The others were identified as a homeless person and two carbon monoxide poisoning victims, said Houston Police Chief Art Acevedo.

In the Southeast, a low-pressure system that developed along the Arctic front created fuel for storms that unleashed at least four tornadoes, said meteorologist Jeremy Grams of the weather service's Storm Prediction Center in Norman, Oklahoma. One ripped through the Florida Panhandle and two through southwestern Georgia on Monday.

The fourth, most severe twister left three dead and homes flattened after it swept overnight through North Carolina's coastal Brunswick County in the state's southeastern corner between Wilmington and Myrtle Beach, South Carolina, the local sheriff's office said early on Tuesday.

After a brief lull on Tuesday that may allow authorities to assess damage, rough weather — including potential twisters — was expected to return on Wednesday into Thursday, Grams said.

“Those very same areas could be affected — that will include tornadoes and damaging winds,” he said.
