Heat, humidity build cells that drop light rain on the valley

Updated September 3, 2023 - 5:44 pm

Storm cells are moving briskly across the Las Vegas Valley early Sunday evening.

Heat and humidity helped the storms develop late in the afternoon.

“They should clear out pretty quick and it should be clear after that,” National Weather Service meteorologist Jenn Varian said.

The cells moving southwest to northeast dropped light rain with some gauges mainly across the southern half of the valley showing less than .05 of an inch.

The coming week should be dry, according to the weather service.

Valley recovers from heavy rain

Interstate 15 reopened after a 7-hour closure early Sunday morning after heavy flooding made travel on the southbound lanes impossible.

As of Sunday morning, the interstate was open in both directions, though debris and water lingered on the shoulders in both directions.

Jean saw over 3 inches of rain in 2 hours Saturday afternoon, according to data from the Clark County Regional Flood Control District.

Flamingo Road near U.S. Highway 95 also experienced flooding that closed lanes Saturday night, but the road reopened around 1 a.m. Sunday. Flamingo Road near Nellis Boulevard was also closed for an hour from flooding Saturday night but reopened around 9 p.m.

No major roads or highways were closed from flooding Sunday morning, according to traffic data from the Nevada Department of Transportation.

Spring Mountains residents still recovering from heavy rainfall from Tropical Storm Hilary that caused major damage to Kyle Canyon, Lee Canyon and Deer Creek roads. A Regional Flood Control District rain gauge showed Mount Charleston received more than two inches of rain between 7 a.m. Friday and 7 a.m. Sunday.

The weather service said Sunday that Las Vegas is on track to have a wetter monsoon season this year than Phoenix. Las Vegas has received 2.42 inches more monsoon rainfall than Phoenix.

Las Vegas has only beaten Phoenix in monsoon rainfall 14 times since 1937, when weather service records began, the weather service said in a post.

Monsoon season runs until Sept. 30.
