Massive dust storm rolls through Arizona

A major dust storm estimated to be 3,000-foot high swept through Arizona on Wednesday night, with near-zero visibility reported in some areas.

A dust storm warning was in place in Phoenix until 9:00pm local time, but other areas were affected earlier -- with trailers thrown off their foundations in Eloy, southeast of Phoenix, according to KPHO-TV.

The Pinal County Sheriff's Office said a barn had also been blown away in the storm.

The storm came after at least one person was killed and several others injured in October after a dust storm caused massive car pileups on an Arizona interstate road.

The National Weather Service says a dust storm warning is issued when strong winds blow large amounts of dust or sand, substantially reducing visibility to less than a quarter-mile.
