The storm resulted in tons of mud and rock piled on city streets. Two unoccupied vehicles parked on Turner Avenue were washed down Ward's Canyon and into the San Francisco River. A third vehicle was tossed onto its side in the canyon about 100 yards from the canyon's confluence with the river. Flash flooding also resulted in damage to a main water line feeding Clifton.

The wider storm

An upper level disturbance as well as tropical moisture from remnants of Tropical Storm Georgette caused widespread rainfall, with locally heavy amounts leading to flash flooding.
