The National Weather Service has issued a flash flood watch for most of Clark County until 9 p.m. as severe weather conditions continue to pass through the valley.
The valley faces a 50 percent chance of severe rainfall and thunderstorms, said Chris Stumps, a meteorologist for the National Weather Service.
Rainfall Saturday night was contained mostly to the northwest valley, Stumps said. Storms left as much as 2.68 inches of rain in the north end of Decatur Boulevard and as little as .04 inches in McCullough Hills in Henderson. The North Las Vegas airport experienced .12 inches of rain while McCarran International Airport remained relatively dry.
Flooding at the intersection of Buffalo and Grand Teton drives left 10 cars stalled, said Tim Szymanski, spokesman for Las Vegas Fire & Rescue. The storms had left three feet of water at the intersection, Stumps said.
Flooding also swept small rocks onto the intersection of Durango and Elkhorn roads, leaving motorists to travel over an inch of debris, Stumps said.
A few thunderstorms are developing south of the valley and north of Mount Charleston, Stumps said. He added that there should be drier air conditions by Monday with a slight chance of thunderstorms from leftover moisture.
Stumps advises motorists to avoid roadways if they do not know how deep it is or if the water is running across the street. He also urges people to get to higher ground in case of flooding.
Although the flash flood warning is in effect until 9 p.m., it may be extended if heavy weather conditions continue into the night, Stumps said.
