"A heavy dust storm whipped through the Valley on Sunday, leaving downed trees and power outages in its wake.

In the East Valley, trees tumbled at several Gilbert sites, including the Power Ranch subdivision, police said.

There were also downed power poles in Queen Creek near the San Tan Mountains and power outages in Tempe, where police directed traffic at several intersections because of signal outages.

More dust could be whipped up today, the National Weather Service said."
