Core Event: 60-plus MPH Gusts Halt Flights and Festival Operations
On Mother’s Day Sunday, wind gusts over 60 mph swept the Las Vegas Valley, prompting a ground stop at Harry Reid International Airport and shutting down the Circuit Grounds, BassPod, and Quantum Valley stages at the Electric Daisy Carnival (EDC) on the Las Vegas Motor Speedway.
Weather Context and Forecasts
NWS meteorologist Dan Berc recorded a 63 mph gust at 7:50 p.m. in Las Vegas. Forecasts called for winds of 20-30 mph with gusts up to 45 mph at the speedway. The NWS gave a 70 % chance of 40-55 mph gusts (20 % chance of 60 mph+) along the I-5 corridor in Southern California and issued a Red Flag warning for Sacramento Valley with north winds of 20-30 mph, gusts up to 50 mph, and humidity of 7-15 %.
Impacts in Nevada
Andre Walls reported 457 flights delayed and visibility down to six miles at Harry Reid and four miles at North Las Vegas Airport; NWS expected winds to ease by Monday noon with the cold front. At EDC, organizers halted the Circuit Grounds, BassPod and Quantum Valley stages. A weather-service alert warned damaging winds could down trees and power lines, cause widespread outages, and make travel difficult for vehicles. Sam Meltzer called the system “a pretty strong front.” Nevada DOT cautioned crosswinds could affect RVs and shuttle buses on I-15.
California Hazard Advisories
The Red Flag warning noted fire-growth risk when strong winds meet low humidity, urging against outdoor burning. High-surf advisories for San Luis Obispo, Santa Barbara, and Ventura counties warned of 5-15 ft breaking waves, dangerous rip currents, and coastal flooding. Gale-force winds were forecast for outer waters from the Central Coast to San Nicolas Island, raising capsizing danger.
Conflicting Reports & Gaps
Observed gusts at the airport reached 63 mph, while speedway forecasts capped gusts at 45 mph, showing a discrepancy between local measurements and broader predictions. Probability ranges for Southern California gusts (40-55 mph vs. 60 mph +) leave uncertainty about peak values.
