A flash flood on Tuesday afternoon has forced Zion National Park to close temporarily to visitors. The park received over an inch of rainfall in an hour, resulting in heavy flooding and mudslides that left more than a foot of muddy debris on the park’s main thoroughfare. An active technical search and rescue operation is underway and State Route 9 has been closed at the town of Rockville until further notice. According to a news release from the National Parks Service, the park will remain closed throughout today, but the park’s shuttle services will remain in operation to evacuate visitors to the Zion Canyon Visitor Center. 

Twitter user Ben Wong posted footage of the flooding taken by his sister, Sabrina Wong, showing a raging torrent of mud and floodwater. 


According to the National Weather Service, more heavy rainfall is forecast for the area on Wednesday. The Utah Division of Emergency Management has advised people in the area to go to higher ground to escape flooding and to avoid attempting to walk or drive through rivers of streams. 

In 2015, seven hikers died during a flash flood in one of the park’s narrow slot canyons, whose unique geology makes them particularly dangerous and prone to flooding during heavy rainfall. Following Tuesday's flash flood, no injuries or deaths have been reported. All narrows and canyons inside the park are also closed until further notice.

Updates to follow.
