WASHINGTON (TNND) — A powerful storm system tore across the United States over the weekend spawning tornadoes, dust storms and wildfires that killed at least 40 people across several states, according to officials.

The storms ravaged Missouri, Arkansas, Texas, Oklahoma, Kansas, Alabama and Mississippi before heading into the Southeast and Mid-Atlantic Monday bringing thunderstorms, hail, damaging winds and the potential for more tornadoes.

Damage surveys from the National Weather Service reported at least five tornadoes touched down in Louisiana, Mississippi and Arkansas Saturday.

Gov. Tate Reeves said six people were killedand more than 200 were displaced in Tylertown, Mississippi while officials recorded the death toll in Missouri reaching 12.

In Oklahoma, storm-driven wildfires damaged more than 400 homes and killed four people, according to the Oklahoma Department of Emergency Management.

Meanwhile, dust storms spurred by high winds claimed almost a dozen lives on Friday. Eight people died in a Kansas highway pileup involving at least 50 vehicles, according to the state highway patrol. Authorities said three people also were killed in car crashes during a dust storm in Amarillo, in the Texas Panhandle.

President Donald Trump said he was "actively monitoring" the situation and would assist state and local officials to help in the recovery. He said National Guard troops were deployed to Arkansas, where officials confirmed three deaths.

"Please join Melania and me in praying for everyone impacted by these terrible storms!" Trump wrote on Truth Social Sunday.
