In Death Valley in California, the driest place in the USA, around a thousand people are stranded after floods.
As the national park administration announced, no injuries were reported after the unusually heavy rains on Friday, but dozens of cars were stuck in the mud.
All roads in and out of the national park were blocked.
"Unprecedented amounts of rain have caused significant flooding," said the national park administration.
Around 500 visitors and 500 employees could not leave the national park in the Mojave Desert west of the casino metropolis Las Vegas for the time being.
All roads will remain closed until officials have an overview of the extent of the damage.
Five centimeters average annual rainfall
The water tore up streets and pushed dumpsters into parked cars.
Several cars were pushed into each other.
Offices and hotels were also under water.
In the Furnace Creek area, 3.7 centimeters of rain fell on Friday
,
almost equaling the previous daily record.
The average annual rainfall in Death Valley is two inches.
The risk of heavy rain is increased by global warming, according to warnings from UN climate experts.
Because a warmer atmosphere can hold more moisture, the frequency, intensity, and amount of heavy rains are increasing in many regions of the world.
