Flash flooding killed one person in Henderson, Nevada, on Friday, October 30, as emergency crews carried out several water rescues during intense thunderstorms across the Las Vegas region.
The danger was not over Saturday night and Sunday, November 1, with the National Weather Service warning that additional heavy rain could produce life-threatening flooding across parts of Arizona, Nevada, Utah, Colorado and New Mexico.

Flash Flooding: Henderson rescue ends in death
Henderson firefighters responded to multiple simultaneous flood rescues at about 1 p.m. local time Friday, according to information released by city officials and storm reports from the National Weather Service.
One person was pulled from a wash near North Pueblo Boulevard and Lake Mead Parkway, then went into cardiac arrest and was pronounced dead at a hospital.
Crews also rescued two people from a vehicle that had been swept off a roadway near the entrance to Lake Las Vegas.
Another person was rescued after climbing onto the roof of a vehicle that became disabled in floodwater.
The National Weather Service recorded flooding at several locations across Henderson and Las Vegas, including Lake Mead Parkway, Boulder Highway, Desert Inn Road, Sahara Avenue and South Nellis Boulevard.
At one location near East Lake Mead Parkway, more than five inches of flowing water covered Racetrack Road, making the route impassable.
Floodwater also carried rocks, mud and other debris onto roads in the area.
More rain expected across the Southwest
Forecasters issued a flash flood watch for the Las Vegas area from Saturday night through Sunday night, warning that rainfall totals above one inch could produce flooding and flash flooding, particularly in mountainous areas.
The National Weather Service office in Phoenix said a separate flood watch covered much of Arizona on Sunday, including Maricopa County, northwest Pinal County and southern Gila County.
That forecast called for widespread showers, embedded thunderstorms and rainfall exceeding one inch in many areas.
Higher terrain southwest of Phoenix could receive between two and four inches, with locally higher totals possible over a 24- to 36-hour period.
Maricopa County was already under a flood warning because streams, washes and other low-lying areas remained vulnerable after earlier rainfall.
Officials also warned that water releases and runoff could affect areas along the Salt River, including low-water crossings near Tempe Town Lake.
Four Corners placed under heightened flood risk
The Weather Prediction Center placed portions of the Four Corners region under a moderate risk of excessive rainfall for Sunday, a designation used when widespread heavy rain and flash flooding are possible.
The risk area includes parts of Arizona, Colorado, New Mexico and Utah.
Forecasters said an unusually moisture-rich Pacific weather system would move across the Southwest and interact with mountainous terrain, increasing the potential for intense rainfall.
The San Juan Mountains in southwestern Colorado were identified as a particular concern because the terrain could force moisture upward and intensify precipitation.
Saturated ground from earlier storms was expected to reduce the land’s ability to absorb new rainfall.
Forecasters said the most significant rainfall period could last roughly 18 hours in parts of the region.
The heaviest rain was expected from the mountains into nearby valleys, where runoff can quickly enter normally dry washes and small streams.
Roads and low-water crossings remain dangerous
Flash flooding can develop faster than road conditions appear to change, especially in desert areas where rain falls upstream from a roadway or community.
Drivers should not enter water covering a road, even if the depth appears shallow.
The National Weather Service continues to warn that most flood deaths occur in vehicles, and floodwater can hide damaged pavement, debris and washed-out sections.
- Do not drive around barricades or through standing or moving water.
- Move to higher ground immediately if a warning is issued nearby.
- Avoid washes, creeks, underpasses and low-water crossings.
- Stay away from flooded roads after the rain ends because water levels can continue rising downstream.
People in flood-prone areas of the Southwest were advised to monitor local alerts and follow instructions from emergency officials through Sunday night.
What happens next
The immediate concern is whether additional rainfall falls over areas already affected by Friday’s storms.
Even where individual flash flood warnings expire, rivers, streams and drainage channels can continue rising because of runoff from higher ground.
Officials are also expected to assess road damage, reopen routes where conditions allow and issue further warnings if thunderstorms develop.
The National Weather Service said the flooding threat could shift across the region as the storm system moves eastward.
Residents and travellers should check local forecasts before setting out and treat any new warning as an immediate safety instruction.
