**UPDATED to include a statement from Yellowstone Superintendent Cam Sholly, touching on the evacuation of tourists already inside the park
Yellowstone National Park announced Monday that all entrances are temporarily closed because of hazardous conditions caused by flooding.
In a news release, the park cited “unprecedented amounts of rainfall” for causing flooding of roadways, mudslides and rockslides.
“Effective immediately, no inbound visitor traffic will be allowed into the park until conditions stabilize and the park can assess damage to roads and bridges and other facilities,” the park stated. “This includes visitors with lodging and camping reservations.”
As of Monday morning, power was out at multiple locations inside a park that spans 3,500 square miles in parts of Montana, Wyoming, and Idaho.
Flooding is so extensive that damaged roads might take weeks or longer to reopen.
