Flooding tied to monsoonal rains, which already have closed Death Valley National Park and Mojave National Preserve, on Monday forced closure of the southern portion of Joshua Tree National Park in California.

A park release Monday evening said park management closed the south boundary road, as well as a five-mile stretch of Pinto Basin Road between Porcupine Wash and Turkey Flats, due to severe flooding. Park staff have evacuated all visitors from the southern portion of the park, the release added.

Road crews will reevaluate the situation tomorrow and will reopen roadways as soon as possible, the release said, adding that all facilities and roadways in the northern portion for the park remain open and available for visitor use.

Heavy rains on Friday led to closure of Death Valley National Park, and similar rains earlier last week forced closure of Mojave National Preserve as roads were undercut and heavily damaged.
