July and August can be deadly there:

Flash flood in Death Valley strands about 1,000 people in national park

Death Valley National Park was closed Saturday after exceptional amounts of rain drenched the park Friday, triggering flash floods that left about 1,000 visitors and park staff stranded.

The park received 1.46 inches of rainfall at the Furnace Creek area — just shy of the previous calendar day record of 1.47 inches, set on April 15, 1988. This amounts to about three-quarters of what the area typically receives in an average year, 1.94 inches, and is the greatest amount ever recorded in August, The lowest, driest and hottest location in the United States, Death Valley averages just 0.11 inches of rain in August.
