The inland U.S. state of Nevada has experienced impacts from at least 11 tropical cyclones or their remnants. The biggest threat from such storms in the state is their associated rainfall and flooding. The wettest storm was from Hurricane Hilary in 2023, which produced 9.20 in (234 mm) of precipitation in Lee Canyon. Hilary caused around $25 million in damage. The remnants of Hurricane Nora in 1997 contributed to two deaths due to weather-related accidents.
