Roads on the south side of Joshua Tree National Park that were closed due to flash floods in southeastern California have reopened.

The park's south entrance as well as the Pinto and Cottonwood Canyon roads reopened Tuesday and the Cottonwood Visitor Center was expected to reopen Wednesday, the National Park Service said.

The southern portion of the vast desert park had to be evacuated on Monday when thunderstorms unleashed the floods.
