LUBBOCK — A historic winter storm has killed at least 21 people, left millions of Texans without power and spun killer tornadoes into the US Southeast on Tuesday (Feb 16).rrThe brutal cold has engulfed vast swaths of the United States, shuttering Covid-19 inoculation centres and hindering vaccine supplies. It is not expected to relent until the weekend.rrOfficials in Texas drew criticism as the state energy grid repeatedly failed, forcing rolling blackouts. Freezing weather stilled giant wind turbines that dot the West Texas landscape, making it impossible for energy companies to meet escalating demand.rrUniversity student Corbin Antu found a way to snowboard in the flat West Texas plains town of Lubbock. He clung to a tow rope as friends in a pickup truck pulled him up and down silent white streets.rr"This is my first time snowboarding out in Lubbock. Trust me, it's not disappointing," Mr Antu said. "There is so much powder out on the ground it feels like it's Colorado almost."rrDEATHS, NO POWER, VACCINE DELAYSrrAt least 21 people have died in Texas, Louisiana, Kentucky and Missouri including four killed in a house fire in Sugar Land, Texas, where the power was out, according to police and local media.rrPresident Joe Biden assured the governors of hard-hit states that the federal government stands ready to offer any emergency resources needed, the White House said in a statement.rrHouston Mayor Sylvester Turner said at a midday news conference that 1.3 million people in his city remain without power. The city is looking for businesses that still have power to open their doors as warming centres.rr"It's critically, critically important to get the power restored as quickly as possible. It's priority number one!" Mr Turner said.rrOfficials in south Texas warned citizens to not bring grills or propane heaters indoors. Hospitals have treated people for carbon monoxide poisoning as they tried to heat icy homes using those items.rrMr Turner said vaccination centres in Houston would remain closed on Wednesday and probably Thursday. The Texas Department of State Health Services said vaccine shipments around the state would be delayed.rr"No one wants to put vaccine at risk by attempting to deliver it in dangerous conditions," department spokesman Douglas Loveday said by email, adding "it is not safe for people to be out across much of Texas."rrIn neighbouring New Mexico, a state spokesman said by email there were delays in some Pfizer vaccine shipments, which were expected to be brief.rrThe deep freeze grounded operations at the Houston Ship channel and curbed output in the nation's largest oil field: The Permian in West Texas. Several oil refineries remained offline.rrFREEZE WILL LINGERrrStorms dumped snow and ice from Ohio to the Rio Grande through the long Presidents Day holiday weekend, and treacherous weather was expected to grip much of the United States through Friday.rrForecasters predicted up to 4 inches (10.2cm) of snow and freezing rain from the southern Plains into the Northeast.rr"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.rrAn Arctic air mass descended over much of the country, pushing temperatures to historic lows on Tuesday, Ms Pagano said. In Lincoln, Nebraska, a reading of -31°F (-35°C) on Tuesday shattered a record set in 1978 of -18°F (-27°C).rrIn typically toasty Dallas-Fort Worth, -1°F (-17°C) broke a record set in 1903 of 12°F (-11°C).rr"It's just dangerous," Ms Pagano said.rrWith more than 4.4 million power outages in Texas alone, authorities shut down inoculation sites and scrambled to use 8,400 vaccines that require subzero refrigeration before they spoiled after a backup generator failed, Harris County Judge Lina Hidalgo said.rrDoses were rushed to area hospitals and Rice University to be injected into the arms of people already at those locations and who did not have to travel on slick roads.rrIn 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.rrOne ripped through the Florida Panhandle and two through southwestern Georgia on Monday.rrThe 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.rrAfter a brief lull on Tuesday, rough weather including potential twisters was expected to return on Wednesday into Thursday, Mr Grams said.rr"Those very same areas could be impacted — that will include tornadoes and damaging winds," he said.
