A Month’s Worth of Rain in a Day in Las Vegas

It’s not often that Las Vegas, Nevada deals with washouts, but that was the case for Sin City on Monday, where nearly a full month’s worth of rain fell in less than 24 hours.

Las Vegas saw a little over two-tenths of an inch of rainfall on Monday, which might not sound like a lot, but that about equals the city’s average rainfall for the whole month of October (0.27″). A streamline of moisture worked up I-15 from southern California on Sunday and early Monday, moving into Las Vegas and dropping a healthy amount of rainfall in the typically bone-dry city.


Las Vegas gets the majority of its annual rainfall during the summer, thanks to monsoonal showers and thunderstorms that can lead to flooding issues. But big Pacific storms during the West Coast’s rainy months can lead to flooding during the winter as well. However, Las Vegas’ desert climate leads to barely four inches of rain a year, so any rainfall is a big deal for Sin City.

The same storm system brought thunderstorms to nearby interior portions of southern California and dropped over an inch of rainfall to some higher elevations near Los Angeles. Southern Arizona also received mostly beneficial moisture on Monday as well.


If you’re heading to Las Vegas this week, however, the forecast looks amazing, with above-average temperatures soaring into the 80s under plenty of sunshine.
