Las Vegas Flash Flooding: 1 Dead, Halloween Rain Forecast

A fast-moving thunderstorm dumped torrential rain and hail on the Las Vegas Valley on Friday afternoon, Oct. 30, 2026, turning streets into rivers, stranding drivers and leading to one death in Henderson. "Las Vegas flash flooding" became one of the most-searched terms in the U.S. on Google overnight, as videos of cars pushing through flooded intersections spread and residents checked whether more rain was coming for Halloween. As of early Saturday, the National Weather Service expected another round Saturday night into Sunday.

What happened on Friday

The National Weather Service issued a severe thunderstorm warning for the east Las Vegas Valley until 1:45 p.m. PDT, citing public reports of hail and torrential rainfall, KSNV News 3 reported. A flash flood warning followed and remained in effect until 3:45 p.m.

Heavy flooding was seen on Eastern Avenue north and south of Interstate 11/U.S. 95, according to KSNV, and hail fell in East Las Vegas. Water also pooled across parking lots in the central valley, including near Maryland Parkway and Sahara Avenue.

One death after three water rescues in Henderson

Henderson crews responded to three swift-water rescues at around 1 p.m., according to KSNV:

• Lake Mead Parkway and North Pueblo Boulevard: Crews pulled a person from a wash. The person went into cardiac arrest, received immediate care and was taken to a local hospital, where they were pronounced dead.
• Lake Mead Parkway east of the Lake Las Vegas entrance: Two people were removed from a vehicle that floodwater had swept off the road. No injuries were reported.
• North Milan Street near Drake Street: A vehicle stalled while trying to cross floodwater. One person climbed onto the roof and was rescued. No injuries were reported.

The person who died had not been publicly identified as of early Saturday, and officials had not released further details on the circumstances.

Power outages and an airport ground stop

Harry Reid International Airport put a ground stop in place because of lightning, lasting through at least 3 p.m., KSNV reported. Travelers flying in or out this weekend should check their airline's app for knock-on delays.

NV Energy reported more than 4,000 customers without power as of 1:40 p.m., most of them in the central valley. That number dropped to just over 2,000 by about 2:15 p.m. Current outage information is on NV Energy's outage map.

Arts District businesses take on water

In downtown Las Vegas, water poured into shops in the Arts District. "It was water everywhere," Lesly Garvey, owner of Los West Coast, told KLAS 8 News Now. She said the damage would likely keep her leather clothing store closed through the weekend.

Karina Carancho, owner of the rave-gear store Plur City, told KLAS that every passing car sent "a wave" of water through her door. She said Halloween is one of the store's busiest weekends and she did not want to close. KLAS noted that the Charleston Boulevard Storm Drain Project is underway in that area and is set to finish at the end of next year, according to the Regional Flood Control District.

Will it rain in Las Vegas on Halloween?

The forecast said yes, most likely after dark. The National Weather Service forecast for Las Vegas, checked early Saturday, called for:

• Saturday (Halloween): Partly sunny, high near 73.
• Saturday night: Rain likely after 7 p.m., 60% chance, low around 63, with gusts up to 20 mph.
• Sunday, Nov. 1: Rain likely before 4 p.m., 60% chance, high near 71.
• Sunday night and Monday: Clearing, with sunshine Monday.

FOX5 Vegas also said trick-or-treaters may run into showers and that the storm moving inland late Saturday into Sunday brings a better chance of widespread rain.

Why Las Vegas floods so fast

Las Vegas averages only a few inches of rain a year, but storms that do arrive can drop a lot of water in a short time. Hard desert soil and wide stretches of pavement absorb little of it, so runoff races into streets and natural washes within minutes. The Clark County Regional Flood Control District maintains a network of detention basins and channels designed to move that water, but heavy cells can still swamp local roads and intersections before the system catches up.

That is why the most dangerous places in a Las Vegas storm are often washes, low-water crossings and dips in the road, exactly where Friday's Henderson rescues happened.

How to stay safe in a flash flood

The National Weather Service's Turn Around Don't Drown guidance is blunt:

• 6 inches of fast-moving floodwater can knock over an adult.
• 12 inches of rushing water can carry away most cars.
• 2 feet of rushing water can carry away SUVs and trucks.

The NWS says more deaths happen each year from flooding than from any other thunderstorm hazard, and that many of them happen in vehicles. Never drive around barriers on a flooded road; the pavement underneath may have washed out. Stay out of washes and flood channels during and after rain, keep children and pets away from moving water, and call 911 if you see someone in danger. If your power goes out, treat any downed line as live.

Part of a bigger Western storm pattern

Friday's storm came during a wet stretch across the Southwest. Last week, record flooding hit the Four Corners region, where the San Juan River broke a 1909 record at Farmington, New Mexico. Our Four Corners flooding explainer covers that event.

Staying safe in a desert storm

Friday's Henderson rescues happened where Las Vegas storms are often most dangerous: in washes and on roads that dip under water. The forecast called for more rain Saturday night and Sunday, so keep an eye on alerts, stay out of the washes and don't drive into moving water.
