Phoenix people awoke on Wednesday to a thick cover of dust on their cars , streets and just about everything else outside after a big sandstorm.

The storm on Tuesday evening grounded airplanes and led to traffic tie-ups . At the height of the storm , visibility（能见度）was reduced to zero . Sandstorms are not uncommon in Arizona and other desert areas , but the size of this one and the dust it raised were highly unusual. “The greatness of this event was really exceptional, ” said Ken Waters , a meteorologist (气象学家) of the Na-tional Weather Service in Phoenix.“People who have been living in Arizona for 30-35 years say this is the biggest one they’ve ever seen.”

“The storm was driven by 60-mile-an –hour winds that collected the sand into a rolling brown cloud and sent it moving across the city , briefly damaging the lights of downtown Phoenix as it passed through . The sandstorm ran about 150 miles before dissipating, and at its peak（最高点） might have grown to as large as 100 miles wide and more than one mile high . The more dust it picks up , the higher the cloud goes, ” Mr. Waters said.

Arizona’s continuing drought –some areas have had no rain for four months – only made conditions worse . The drought in southern Arizona is the fifth-most extreme in the past 50 years . “The sandstorm closed Phoenix International Airport for about 45 minutes starting around 8 p.m , when visibility was reduced to one –eighth of a mile.” said Julie Rodriguez , an airport spokeswoman . “ Two flight were canceled and sand was also blown into some buildings.”

“Several thousand homes lost power in the area after the winds blew down power lines . The winds turned over a truck on Interstate 8 near Casa Grande , but caused no serious injuries,” officials said.
