Clark County and Las Vegas face extreme and compounding disaster risks. Summer temperatures regularly exceed 115°F and Las Vegas holds the record for most consecutive days above 110°F. Flash flooding from the surrounding mountains strikes the valley with little warning — the August 2022 floods submerged vehicles on the Las Vegas Strip. The county sits near active fault systems and Nevada has a history of significant earthquakes.
