A gust of wind sweeps over bare soil, kicking up enough dirt and dust to cut visibility to nearly zero, and for drivers, the dust storm seems to come out of nowhere.Such conditions resulted in a pileup on Interstate 70 last week in western Kansas involving dozens of cars and trucks that left eight people dead.

Friday's strong winds and dust storm led to 42 crashes, three of which were fatal, according to the Texas Department of Public Safety on Monday.

The Kansas Highway Patrol reported Saturday that eight people died in an interstate pile-up after a dust storm caused a 55-car pile-up.

A powerful storm system that tore across the United States in recent days is winding down Monday, but in its wake are devastated communities across states hit with violent tornadoes, wildfires and dust storms spun off by the massive system.

The weakening but still volatile weather system was moving Monday into the U.S. Southeast and Mid-Atlantic, bringing thunderstorms, hail, damaging winds and the potential for more tornadoes.
