September storms soak parts of Las Vegas Valley

Thunderstorms returned to the Las Vegas Valley, albeit briefly, on Monday.

Scattered storms hit the northern and western valleys, including Summerlin and Centennial Hills, in the afternoon. On Monday night, a few storms skirted the northern edges of the valley, producing lightning, thunder and gusty conditions.

Also, Death Valley National Park in eastern California was affected by a flood advisory until 7:30 p.m., the National Weather Service said.

A low-pressure system from the Pacific Ocean is passing through Southern Nevada, igniting the showers and windier conditions.

Weak monsoon season

The monsoon season, which began in late June and lasts through September, has been almost nonexistent for the valley during a very dry year.

The airport registered a trace of rain Sept. 6 but it has seen no measurable rain this month. The average September precipitation for Las Vegas is 0.32 inches. Last year, the valley recorded 0.28 inches.

In August, the airport recorded 0.18 inches of rain, its wettest month since February (0.35). But the August average is 0.32. Reid has registered 0.69 inches of precipitation so far in 2026.

Reid saw no measurable rain in July. On June 23, the airport recorded 0.02 inches of rain, breaking a rainless streak of 124 days. It was the only rainfall of the month.
