In early August 2022, flash floods soaked Furnace Creek in Death Valley, the driest place in North America. In just three hours on August 5, a thousand-year rainfall event dropped 75 percent of the local average annual rainfall, which is just under 2 inches (5 centimeters). Flood water washed debris over roads, swept away and buried cars, knocked a water facility offline, damaged buildings, and stranded about a thousand visitors and staff in Death Valley National Park.

The deluge dropped 1.46 inches (3.7 centimeters), which came close to breaking the single-day record for highest rainfall ever received in the park, which was 1.47 inches in April 1988. It did, however, break the record for the most rain recorded in August, which averages just over a tenth of an inch for the whole month.

By August 6, the flood water had mostly receded, and the stranded visitors were able to exit the park escorted by National Park Service personnel. But extensive mud and gravel deposits still remained, leaving some roads impassable; they were expected to remain closed into mid-August, according to a statement by the Park Service.
