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.

According to the SPC: “The HIGH risk area almost always means a major severe weather outbreak is expected, with great coverage of severe weather and enhanced likelihood of extreme severe (i.e., violent tornadoes or extreme convective wind events over a large area).”
