Following a widespread thunderstorm over Washington County Thursday night, the Zion-Mt. Carmel Highway remains closed from the east entrance of Zion National Park to Canyon Junction in Zion Canyon, according to a social media post from Washington County Emergency Services. If all goes well, however, the highway could be reopen Friday afternoon. Prior to Thursday’s storm, Zion National Park received 3 inches of rain over a short period of time Wednesday that resulted in flooding and landslides that occurred on the switchbacks below the tunnel on the east side of the park.
