A dust storm in the Phoenix, Ariz., area left about 25,000 without electricity Thursday night and could impact visibility for fireworks over the Fourth of July holiday.
The storm, closely followed by rain, felled power lines and trees, and caused minor street flooding in some areas.
Phoenix Sky Harbor International Airport had instituted a ground stop for about 30 minutes in response to the wall of dust that rolled through the valley in the early evening, and many area roads became waterlogged.
The wall of dust gathered steam south of the metropolitan area and whooshed into Phoenix at about 7:30 p.m. It lingered three to four hours, meteorologist Charlotte Dewey of the National Weather Service told the Arizona Republic.
While the National Weather Service does not predict dust storms, Dewey said they are often associated with thunderstorms. The Phoenix area is expecting a 20% to 25% chance of rain this weekend.
