Tropical Storm Rachel swept through Southern California before reaching the Las Vegas Valley over the weekend, causing substantial rainfall and some flooding, particularly in areas around the Strip.
The National Weather Service in Las Vegas reported that the city received 1.08 inches of rain from midnight through Sunday morning, tying the record for the highest daily total in October, previously set on October 12, 1947.
This significant downpour partially mitigated what has been a notably dry year for Las Vegas, as the total from this storm nearly equaled the city's annual rainfall. Prior to this weekend, Las Vegas had managed only 1.1 inches of rain throughout the entire year, which is over two inches below the average, according to the NWS.
Flash floods led to the closure of several roads near the Strip, including parts of East Flamingo Road, Koval Lane, and Winnick Avenue. Social media showcased videos and images capturing rising water levels, especially around the LINQ Promenade. This area is designed with a garage that allows excess water to flow through, according to the Clark County Regional Flood Control District.
Due to the weather, some scheduled events were canceled, including the conclusion of the Age of Chivalry Renaissance Festival and a breast cancer awareness walk along the Strip organized by the Susan G. Komen organization.
By Monday, the road closures had been lifted, although the disruptions may have an impact on visitor and travel statistics. In August, Las Vegas experienced a 4% decline in visitation compared to the previous year, marking this year's largest year-over-year drop reported by the Las Vegas Convention and Visitors Authority. Traffic at Harry Reid International Airport also decreased by 9% in August, and the airport issued a weather advisory for all flights on Sunday and Monday. Currently, air traffic is tracking 7% behind last year's figures, which had also seen a 7% decrease from 2024.
With around five weeks to go before the annual Formula One Las Vegas Grand Prix on November 19, construction related to the race is progressing. Some of the roadways affected by the flooding are part of the planned race circuit, but Formula One has not announced any construction delays or issues.
Nevada has faced severe weather complications recently; in late August, wildfires prompted evacuation notices for tens of thousands of residents in the Reno area. Local casinos supported the firefighting efforts by offering discounted rates for evacuees, and various companies contributed to relief initiatives.
