Strong damaging winds of 80–100 mph (130–160 km/h) or higher occur a few times each year around the Smoky Mountains, mainly during the cool season from October to April, as a result of a phenomenon known as mountain waves. Mountain waves are strongest in a narrow area along the foothills, and can create extensive areas of fallen trees and roof damage, especially around Cades Cove and Cove Mountain. Strong winds created by mountain waves were a contributing factor in the devastating Gatlinburg fire on November 28, 2016 during the 2016 Great Smoky Mountains wildfires. Damaging winds can also be generated by strong thunderstorms, with tornadoes and strong thunderstorm complexes (also known as mesoscale convective systems) occasionally affecting the Smoky Mountains.
The park was established in 1934.
