UTAH (KLAS) — A mudslide has closed State Route 9 through Zion National Park. The National Park Service (NPS) says the road will remain closed to inbound traffic due to flash flooding and an active technical search and rescue operation.

A little over an inch of rain fell an hour in the park, according to NPS.

Park traffic is being diverted outbound at the south and east entrances, as staff works to clear the debris.

Ben and Sabrina Wong sent video of flooding in the area to 8 News Now. They thanked the staff at Zion Adventure Company for helping the family to get to safety during the inclement weather situation.

Park narrows and canyons are also closed until further notice. Zion shuttles are transporting visitors from up canyon to the visitor center, and town shuttles will run past their usual 6 p.m. MT to aid with traffic.

NPS says east and west alternate routes are available. Motorists may take Highway 59 from Hurricane, Utah, to Fredonia Arizona, or Highway 14 from Cedar City, Utah, to Long Valley Junction and Highway 89. Avoid the area.
