Flooding, power outages, and downed trees were among the issues national parks were facing in the aftermath of Helene, which evolved from tropical storm to hurricane and back to tropical storm as it rampaged from the Gulf of Mexico north into Appalachia.

Tropical Storm Helene has blown away, but units of the National Park System are struggling to recover in her wake. All of the Blue Ridge Parkway in North Carolina remained closed Sunday, many roads in Great Smoky Mountains National Park were closed, and Congaree National Park in South Carolina was closed due to loss of power and functioning water systems.

As Tropical Storm Helene continues its northward trajectory through the Gulf of Mexico, gaining strength along the way, some units of the National Park System were closing before the storm hits.

Construction of the Transcanyon Waterline at Grand Canyon National Park will require the closure of Phantom Ranch from January 2-March 30.
