The monsoon season has been absent across the Las Vegas Valley, but it arrived in Henderson on Monday afternoon. Around 1:30 p.m., a strong storm inundated several neighborhoods in Henderson, causing minor flooding near Nevada State University and Wagonwheel Drive. Gauges at the Regional Flood Control District recorded about 0.55 inches of rain in that area, while the Mission Hills section measured 0.51 inches. Other parts of east Henderson saw measurable rainfall, and a few spots near Boulder City logged 0.12 inches.
The National Weather Service issued a statement Monday morning noting “increased tempest chances chiefly on and southeast of I‑15” for the afternoon. It warned to expect “gusty outflow winds, blowing particulate and little downpours” with these storms.
The monsoon season, which runs from late June through September, has been nearly nonexistent in the valley during this particularly dry year.
Harry Reid International Airport has recorded 0.18 inches of rain this month, its wettest period since February (0.35 inches). The August average is 0.32 inches. So far in 2026, Reid has accumulated 0.69 inches of precipitation; the average through mid‑August is 2.64 inches. In 2025, the airport had recorded 2.05 inches by mid‑August.
Reid saw no measurable rainfall in July, though it logged a trace on July 19. On June 23, the airport recorded 0.02 inches of rain, breaking a rainless streak of 124 days. That was the sole rainfall for the month.
**Another extreme heat warning**
Southern Nevada remains under an extreme heat warning until 8 p.m. Friday. Forecasters expect “dangerously blistery conditions” this week, with temperatures ranging from 108 to 112 degrees across the valley. The weather service said the average high for late August is 102 degrees.
The warning was issued Monday morning, roughly 12 hours after a previous extreme heat warning expired.
This week’s extreme heat warning is the fourth in the past month. The summer’s first extreme heat warning lasted from July 23 to July 27. The second began July 30 and was extended several times before expiring on August 9.
**Cooling stations**
Clark County has activated cooling stations at community centers, libraries and other buildings across the valley through Wednesday. The cooling stations’ hours vary depending on the location. Sites are available in Las Vegas, North Las Vegas and Henderson.
The stations are open to anyone needing relief from the heat, the county said. Additional information can be found at the Southern Nevada Homelessness Continuum of Care’s website at helphopehome.org/get‑help/.
