Severe thunderstorms struck parts of the Las Vegas Valley on the night of September 28, 2026. These storms triggered local flood advisories, high winds, and significant flight delays across southern Nevada. The sudden weather shift brought much-needed precipitation to the region while disrupting evening travel and commutes.
Flood Advisories and Impacted Areas
The National Weather Service issued a flood advisory that remained in effect through 11:15 p.m. for several communities. Radar tracking indicated intense storm cells dropping heavy downpours, frequent lightning, and loud thunder across:
- Las Vegas
- Summerlin
- Spring Valley
- Centennial Hills
- Red Rock Canyon
- North Las Vegas Airport
Recorded rainfall totals across the affected sectors ranged between 0.25 inches and 1 inch. The Henderson Fire Department’s technical rescue team was dispatched to assist during the storms. They successfully removed one person from a stalled vehicle near Moonwalk Terrace and East Paradise Hills Drive.
Airport Delays and Regional Weather Systems
The severe weather caused noticeable disruptions in air travel. Earlier in the evening at 5:00 p.m., the Federal Aviation Administration reported that departing flights at Harry Reid International Airport experienced departure delays averaging about three and a half hours. Arriving flights faced shorter delays of around 30 minutes.
Meteorologists explained that a low-pressure system drove the active weather. This system pulled abundant tropical moisture from the remnants of Hurricane Odalys. It also generated flash flood warnings earlier in the day for Mohave County in northwestern Arizona, San Bernardino County in Southern California, and south-central Clark County.
Cooling Trend and Upcoming Forecast
The storm system offered temporary relief from lingering summer heat. It dropped daytime high temperatures into the low 80s, which is roughly 10 degrees below normal for late September. Forecasters noted a lingering 20 percent chance of morning and early afternoon rain on Tuesday, with precipitation shifting toward Arizona later in the day.
Clear skies and a drier pattern are expected to return by Wednesday. High pressure will build back over the Desert Southwest, driving temperatures up toward seasonal norms for the remainder of the week.
