Las Vegas, Nev. – Thunderstorms rolling across southern Nevada Tuesday could trigger dangerous flash flooding, especially in Clark County, Death Valley, and San Bernardino County. Heavy downpours, frequent lightning, and gusty winds are expected through the evening, with the National Weather Service issuing a Flash Flood Watch for the region.
According to the National Weather Service in Las Vegas, storms will initially build over mountain ranges before moving into nearby valleys, where flood risk quickly rises. The strongest cells are capable of producing rapid roadway flooding, cutting off desert highways and creating hazardous travel conditions in low-lying areas.
Communities including Las Vegas, Henderson, and Boulder City face the risk of street flooding during peak rainfall. Drivers along U.S. 95 and Interstate 15 are urged to avoid underpasses and flood-prone stretches where water can rise quickly. In California, San Bernardino County and Death Valley hold the greatest chances of widespread flooding, with runoff flowing into dry washes and canyons.
Officials warn residents to charge devices, avoid unnecessary travel, and stay alert to rapidly changing conditions. Additional advisories could be issued if storms persist into the overnight hours.
