Las Vegas flash flooding: Light-to-moderate rain to continue through Sunday morning as Clark, Lincoln and Mohave counties face highest rainfall risk, says NWS

Residents in and around Las Vegas, Nevada, have been warned about possible flash flooding on Sunday, November 1, as heavy rain is expected to continue across parts of the southwestern United States. The National Weather Service (NWS) has warned that persistent rainfall could lead to flooding, with locally heavy downpours creating the risk of flash floods in vulnerable areas. "Light-to-moderate rainfall will continue through the morning, with highest rainfall accumulations across Clark, Lincoln, & Mohave counties. This afternoon, shower & thunderstorm chances return before conditions dry out tonight for the start of the week," the NWS said.

The NWS Las Vegas issued a flood advisory for northeastern Clark County until 9 am PST Sunday after persistent light-to-moderate rainfall overnight caused nuisance flooding along low-water crossings. "Flood Advisory in effect for northeastern Clark County Now through 9 AM PST Persistent light-to-moderate rain overnight resulted in nuisance flooding across northeastern Clark County along low water crossings - particularly near Valley of Fire Drive with caution this morning!," the weather advisory for Clark County read.

The weather warning comes as the region experiences widespread rainfall, with showers expected to continue through Sunday afternoon. Although most rainfall is expected to remain light to moderate, some areas could receive heavier downpours, increasing the risk of flooding on roads, in low-lying areas and near waterways.


"Flood Advisory in effect for southern Mohave County Now through 10 AM PST / 11 AM MST Persistent light-to-moderate rain overnight resulted in nuisance flooding across southern Mohave County along low water crossings. Drive with caution this morning if out on the roads!," read another tweet.

According to the NWS, moderate to heavy rainfall could bring between half an inch and one inch of rain to affected areas in Las Vegas. The NWS warned that excessive runoff could cause rivers, creeks and streams to overflow and flooding is also possible in urban areas, locations with poor drainage and low-water crossings.

How much rain is expected in Las Vegas on Sunday?

According to NWS Las Vegas forecast, the weather officials expect rainfall to continue across the region through Sunday afternoon, although conditions could vary between neighborhoods. Las Vegas is forecast to receive between 0.25 and 0.50 inches of rain, while some surrounding areas could record higher totals. Parts of Mohave County, particularly higher elevations, could receive more than two inches. Lincoln County and other parts of Mohave County could see between 0.75 and 1.50 inches.
