The threat of tornadoes moved east into the Mississippi Valley and Deep South on Saturday, a day after a massive storm system moving across the country unleashed winds that damaged buildings, whipped up dust storms that caused deadly crashes and fanned more than 100 wildfires in several central states.
Multiple tornadoes were reported in Missouri on Friday, just some of the extreme weather that was forecast to affect an area home to more than 100 million people. Winds gusting up to 130 km/h were predicted from the Canadian border to Texas, threatening blizzard conditions in colder northern areas and wildfire risk in warmer, drier areas to the south.
Three people were killed Friday in car crashes during a dust storm in Amarillo County in the Texas Panhandle, according to Sgt. Cindy Barkley of the state’s department of public safety. One pileup involved an estimated 38 cars.
“It’s the worst I’ve ever seen,” Barkley said, calling the near-zero visibility a nightmare. “We couldn’t tell that they were all together until the dust kind of settled.”
Evacuations were ordered in some Oklahoma communities as more than 130 fires were reported across the state. The State Patrol said winds were so strong that they toppled several tractor-trailers.
“This is terrible out here,” said Charles Daniel, a truck driver hauling a 14.6-metre trailer along Interstate 40 in western Oklahoma. “There’s a lot of sand and dirt in the air. I’m not pushing it over 55 mph. I’m scared it will blow over if I do.”
Forecasters said the severe storm threat would continue into the weekend with a high chance of tornadoes and damaging winds Saturday in Mississippi and Alabama. Heavy rain could bring flash flooding to some parts of the East Coast on Sunday.
Experts say it’s not unusual to see such weather extremes in March.
“What’s unique about this one is its large size and intensity,” said Bill Bunting of the National Weather Service’s Storm Prediction Centre in Norman, Okla.
Tornadoes, large hail
The weather service said at least five tornadoes were reported in Missouri on Friday, including one in the Saint Louis area. Several buildings were damaged in the storm, including a strip mall in Rolla, Mo., where a tornado was reported Friday afternoon.
The Storm Prediction Centre said fast-moving storms could spawn twisters and hail as large as baseballs, but the greatest threat would come from straight-line winds near or exceeding hurricane force, with gusts of 160 km/h possible.
“Potentially violent” tornadoes were expected Saturday in parts of the central Gulf Coast and Deep South into the Tennessee Valley, according to the National Weather Service.
The Storm Prediction Centre said parts of Mississippi including Jackson and Hattiesburg and areas of Alabama including Birmingham and Tuscaloosa would be at a high risk. Severe storms and tornadoes were also possible across eastern Louisiana, western Georgia, central Tennessee and the western Florida Panhandle.
Wildfires amid dry, gusty conditions
Wildfires in the Southern Plains threatened to spread rapidly amid warm, dry weather and strong winds, and evacuations were ordered Friday for some communities in Texas, Oklahoma, Kansas, Missouri and New Mexico.
A blaze in Roberts County, Texas, northeast of Amarillo, quickly blew up from less than two square kilometres to an estimated 85 square kilometres, the Texas A&M University Forest Service said on X. Crews stopped its advance by Friday evening.
About 90 kilometres to the south, another fire grew to about 10 square kilometres before its advance was halted in the afternoon.
The Oklahoma Department of Emergency Management activated its emergency operations centre due to several fast moving fires that prompted evacuations of the town of Leedey in the western part of the state and in a rural area east of Norman.
Firefighters had been prepositioned in certain areas, which helps authorities jump on blazes early, said Andy James, Oklahoma Forestry Services fire management chief. Firefighting aircraft were also deployed in some parts of Oklahoma and Texas but were generally unable to fly due to low visibility from smoke and dust, he added.
Friday evening, the National Weather Service said a “complex of extremely dangerous fires” was located northeast of Oklahoma City, near Stillwater, and urged some people in the city of about 50,000 to evacuate. Officials issued mandatory evacuation orders via social media that included homes, hotels and a Walmart.
Officials urged people in some areas of central Missouri’s Camden County to evacuate due to wildfires, and the State Highway Patrol warned via social media that they were nearing homes and businesses.
Roughly 190 kilometres of Interstate 70 in western Kansas were temporarily shut down due to blowing dust and limited visibility.
High winds also knocked out power to more than 216,000 homes and businesses in Texas, Oklahoma, Arkansas and Missouri, according the website poweroutage.us.
Blizzard warnings in Northern Plains
The U.S. National Weather Service issued blizzard warnings for parts of far western Minnesota and far eastern South Dakota starting early Saturday. Snow accumulations of 7.6 to 15.2 centimetres were expected, with up to 30 centimetres possible.
Winds gusting to 97 km/h were expected to cause whiteout conditions.
