OKLAHOMA CITY (AP) 鈥 A sprawling storm system crossing the U.S. on Friday caused deadly crashes, damaged buildings and fanned more than 100 wildfires in several central states, prompting evacuation orders in some communities. Nearly a half dozen tornadoes were reported in Missouri, and threats of more loomed for the Mississippi Valley into the night and the Deep South on Saturday.
The National Weather Service warned of extreme weather across of the country that is home to more than 100 million people. Powerful winds gusting up to 80 mph (130 kph) were forecast from the Canadian border to Texas.
Three people were killed Friday in car crashes caused by a dust storm in the Texas Panhandle, according to Sgt. Cindy Barkley of the state鈥檚 department of public safety.
鈥淚t鈥檚 been a nightmare out here,鈥 Barkley said, adding that it was difficult to assess many of the crashes due to the near-zero visibility.
Nearly 150 fires were reported in Oklahoma, Andy James, Oklahoma Forestry Services fire management chief, told KOCO-TV. The State Patrol said on the social platform X that winds toppled several tractor-trailers.
鈥淭his is terrible out here,鈥 Charles Daniel, a truck driver hauling a 48-foot (14.6-meter) trailer along Interstate 40 in western Oklahoma, said of the high winds. 鈥淭here鈥檚 a lot of sand and dirt in the air. I鈥檓 not pushing it over 55 mph. I鈥檓 scared it will blow over if I do.鈥
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 .
鈥淲hat鈥檚 unique about this one is its large size and intensity,鈥 said Bill Bunting of the weather service's Storm Prediction Center in Norman, Oklahoma. 鈥淎nd so what that is doing is producing really substantial impacts over a very large area.鈥
Tornadoes hit amid storm outbreak
The National Weather Service said at least five tornadoes were reported in Missouri, including one in Saint Louis.
鈥淭his is a life threatening situation. Seek shelter now!鈥 the agency warned on X.
The Storm Prediction Center 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 100 mph (160 kph) possible.
A tornado watch was issued until 11 p.m. for central and eastern Missouri, including St. Louis, as well as parts of Illinois and Arkansas.
Other areas at risk included parts of Iowa, Kentucky, Tennessee and Mississippi.
About 47 million people faced an enhanced to moderate severe storm threat from Madison, Wisconsin, to Birmingham, Alabama.
Forecasters grew increasingly worried that intense thunderstorms farther south will likely bring an even greater tornado threat Saturday.
The Storm Prediction Center said parts of Mississippi including Jackson and Hattiesburg and areas of Alabama including Birmingham and Tuscaloosa will be at a high risk. Severe storms and tornadoes are also possible across eastern Louisiana, western Georgia, central Tennessee and the western Florida Panhandle.
鈥淲e have a lot of confidence that we most likely will have a tornado outbreak tomorrow,鈥 Storm Prediction Center meteorologist Evan Bentley said in an online briefing.
Several buildings were damaged in the storm, including a strip mall in Rolla, Missouri, where a tornado touched down Friday afternoon.
Wildfires break out amid dry, gusty conditions
Wildfires in the Southern Plains threatened to spread rapidly amid warm, dry weather and strong winds, and evacuations were ordered 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 a square mile (about 2 square kilometers) to an estimated 32.8 square miles (85 square kilometers), the Texas A&M University Forest Service said on X. Crews stopped its advance by the evening.
About 60 miles (90 kilometers) to the south, another fire grew to about 3.9 square miles (10 square kilometers) before its advance was halted in the afternoon.
The Oklahoma Department of Emergency Management activated its emergency operations center 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, James said. 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.
In the evening, the National Weather Service said a 鈥渃omplex of extremely dangerous fires鈥 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.
Jennifer Thompson, a National Weather Service meteorologist in Norman, described the fire conditions in the central and northern parts of the state as historic and highly anomalous.
Roughly 120 miles (190 kilometers) of Interstate 70 in western Kansas shut down due to blowing dust and limited visibility, and roads in the state鈥檚 east were closed amid wildfires and smoke.
A dust storm in Amarillo County, Texas, caused a crash involving an estimated 38 cars.
鈥淚t鈥檚 the worst I鈥檝e ever seen,鈥 Barkley said. 鈥淲e couldn鈥檛 tell that they were all together until the dust kind of settled.鈥
Officials urged people in some areas of central Missouri鈥檚 Camden County to evacuate due to wildfires, and the State Highway Patrol warned via social media that they were nearing homes and businesses.
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 National Weather Service issued blizzard warnings for parts of far western Minnesota and far eastern South Dakota starting early Saturday. Snow accumulations of 3 to 6 inches (7.6 to 15.2 centimeters) were expected, with up to a foot (30 centimeters) possible.
Winds gusting to 60 mph (97 kph) were expected to cause whiteout conditions. Combined with a light glaze of ice, travel in the area could be treacherous that day, the weather service said.
