The death toll from the sweeping storm system climbed to at least 31 in six states Saturday night

The Kansas Highway Patrol reported today that an accident involving more than 50 automobiles occurred during a wind-whipped dust storm in Sherman County, Kansas yesterday.

The death toll from a storm system that swept from the southern Plains to Alabama and Tennessee now stands at 31.

The deaths in Mississippi bring the total death toll from the sweeping storm system to at least 30. The number of deaths confirmed in each state are shown below: Missouri 12, Kansas 8, Arkansas 3, Mississippi 4, and Texas 3, Oklahoma 1.

The incidents occurred about 3:22 p.m. yesterday on Interstate 70 near milepost 28 in Sherman County, according to a Kansas Highway Patrol statement.

The highway patrol said that several more were hurt and hospitalized.  The precise number of injured persons was unknown.

"A strong weather front with high winds moved into northwest Kansas from Colorado, causing a severe dust storm," it said. "With near zero visibility, traffic began to slow, resulting in multiple crashes."

“My thoughts are with those affected by this tragic event,” Gov. Laura Kelly said in the statement.  “I encourage all motorists to remain vigilant as the potential for further weather events continue today.”

Those attempting to locate missing loved ones thought to be involved in the collisions should contact the Kansas Highway Patrol at 785-827-4437.

The Interstate remained blocked.  Calvin Reed, secretary of the Kansas Department of Transportation, stated that reopening "will take time."

A swirling low pressure system has been linked to scores of tornado reports, fires in Texas and Oklahoma, and dust clouds that have reduced visibility on the system's southern side.
