The park has been temporarily closed at all gates due to flooding and rock slides. 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. This includes visitors with lodging and camping reservations. https://www.nps.gov/yell/learn/news/220613.htm
It looks likely all the parks in and near the northern loop of the park will be closed for long periods of time. Likely the rest of the year and maybe even longer.
