Tropical Depression Mario, lurking off Mexico’s Pacific coast, could bring some showers to Las Vegas later this week.
The National Weather Service, in a post on X, said Mario “will continue to weaken off the Baja California Coast. However, moisture from the storm will continue to push northward into our forecast area mid-to-late week.”
Mario first gained tropical storm strength Friday before weakening into a tropical depression just hours later, the Associated Press reported. On Sunday, it again gained tropical storm status. On Tuesday, it weakened to a tropical depression.
In August 2023, the remnants from Hurricane Hilary wreaked havoc on parts of the valley and surrounding mountains. It forced the closure of Earl B. Lundy Elementary School on Mount Charleston, which recently reopened.
Very dry monsoon season
The last time Harry Reid International Airport saw measurable rain was July 3, at the beginning of monsoon season, when it recorded .02 inches.
So far, this is the fourth-driest monsoon season on record, said Chris Outler of the 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 of rain (average is 2.27). A normal rainfall year in Las Vegas is 4.18 inches.
