Dust storms have proven deadly to motorists across the U.S. for years. Authorities say a dust storm last week reduced visibility to nearly zero on Interstate 70 in western Kansas.

Dust storms raged across New Mexico on Tuesday, snarling highway traffic as the National Weather Service pushed an emergency alert to cellphones that warned of zero-visibility conditions and adverse health consequences for infants and the elderly.

Another round of intense dust storms has led to multiple crashes along New Mexico highways and interstates, officials said.
