Monsoon storms fail to appear for most of Las Vegas Valley
Southern Utah, eastern California and northern Arizona all saw some monsoon storms Tuesday.
But not for a large portion of the Las Vegas Valley.
Harry Reid International Airport recorded a trace, according to Matt Woods of the National Weather Service. The last time the airport saw measurable rain was July 3, when it recorded .02 inches.
Parts of Henderson and the southwest valley saw rain totals ranging from .04 to 0.67 inches, according to gauges operated by the Regional Flood Control District. Henderson Executive Airport registered 0.24 inches. Rainbow Canyon in the Mount Charleston area recorded 0.28 inches.
Even though there was a 70 percent of rain Tuesday, Woods said the storms “didn’t survive well” when they approached the valley.
Very dry monsoon season
So far, this is the fourth-driest monsoon season on record, said Chris Outler of the National Weather Service. The Las Vegas monsoon season runs from July 1 to Sept. 30.
The driest years are 2020 and 1944 (tied with a trace) and 2010 (0.01).
So far in 2025, the airport has seen 2.05 inches (average is 2.27). A normal rainfall year in Las Vegas is 4.18 inches. The average August rainfall at Reid is 0.34 inches.
