Severe thunderstorms and flash flooding have hampered park operations at Canyon de Chelly National Monument in northeast Arizona since the 2010 monsoon season started several weeks ago, and have impacted visitor attendance. Large floods on Aug. 1 destroyed the footbridge to Antelope House and made upper reaches of the canyons impassible. On Aug. 3, with thunderstorms building again, members of the park staff were closing the visitor center when they saw a tornado just north of the park.
