The storm started Thursday and pushed through the Southwest, including Arizona, Oklahoma, Texas, New Mexico, Utah, on Sunday. It is expected to continue moving east through the week, threatening plans for the busiest travel days of the year, the Associated Press reported.
By early Sunday, the weather was blamed for at least eight deaths related to fatal traffic accidents. The storm caused hundreds of car accidents, including one that injured three members of Willie Nelson’s band when their bus hit a pillar on Interstate 30 about 75 miles northeast of Dallas. Three people in Texas reportedly died in a pile-up involving almost a dozen vehicles.
