Many vehicles in parking lots were submerged in muddy water. Many homes, condos, and businesses flooded, and three dogs drowned in one home.

Significant flash flooding affected much of the Las Vegas Valley. Numerous roads were closed, and several people were rescued from cars. A church was damaged by three feet of water when a retaining wall collapsed. Several people were rescued from washes. One man died when he fell into the Pittman Wash and was swept downstream.
In addition to strong winds and large hail, redeveloping severe thunderstorms produced heavy downpours which resulted in severe flash flooding in the southeast Las Vegas Valley. In Henderson, raging flood waters turned roads into rivers up to three and four feet deep. Water and mud slides closed many roads, including U.S. Highway 95, for several hours. One man was drowned when a strong current swept him under his vehicle as he tried to move it off his neighborhood street. Rescue workers performed a number of swift water rescues until as late as 8:30 pm PST. Four people were hospitilized. Flooding also resulted in the release of titanium dioxide gas (non-toxic) at the TIMET plant. Extensive damage to roads and buildings prompted the Governor to declare Henderson a disaster area.
