Two people died in flash floods that struck in Las Vegas and parts of southern Nevada state, USA, on 11 August 2022. The National Weather Service said the rain was brought by the current “restless” monsoon, which is the wettest in 10 years.
From late 11 August 2022 lightning and thunderstorms accompanied by heavy rain caused flash flooding in parts of southern Nevada including Las Vegas. This is the second flash flood event in the city in the last two weeks. A similar storm caused flash flooding in the city on 28 July 2022.
The weather station at Harry Reid International Airport (LAS) recorded 0.58 inches (15 mm) on 11 August. The National Weather Service in Las Vegas said, “with 0.58 inches (15 mm) added to the tally yesterday, the monsoon season in Las Vegas has delivered 1.28″ (32.5 mm) of rainfall so far! That makes this the wettest monsoon in ten years! And we’ve still got a month and a half left to add to our total!”
Media reported flash floods swept through the iconic Las Vegas strip, flooding casino buildings and parking lots. Firefighters rescued victims from vehicles trapped in floods. Las Vegas Fire and Rescue said “There were 3 total responses for stalled vehicles in flood waters. All occupants were evacuated to safety with no medical needs or patient transport required.”
Associated Press reported one person died in floodwaters in the Las Vegas Boulevard area, while public works crews and firefighters found a man’s body on 12 August in a flood channel in the same area.
Further heavy rain fell on 12 August. NWS Las Vegas said gauges along Kyle Canyon Road measured over 0.5″ (13 mm) in 30 minutes and issued a Flash Flood Warning for part of northwestern Clark County.
Heavy rain is forecast for other areas in the region. As of 13 August Flash Flood Warnings were issued for Mohave County in northwestern Arizona and San Bernardino County in southern California.
Recently hundreds of people were left stranded by flash floods in parts of Death Valley National Park straddles eastern California and Nevada after nearly a year’s worth of rain fell in just three hours on 05 August 2022.
