The Chimney Tops 2 Fire was reported in Great Smoky Mountains National Park near Gatlinburg, TN at approximately 5:30 p.m. on Wednesday, November 23, 2016. The wildfire began burning in a remote location of the park (Chimney Tops) in steep terrain with vertical cliffs and narrow rocky ridges, making access to the wildfire area difficult for firefighting efforts. Between Thursday and Saturday (November 24-26), crews identified and worked to establish a containment area lower down on the mountain where there was a higher chance of success to stop the fire. Sunday, November 27 the relative humidity dropped and a weather inversion lifted, which increased fire activity. Three helicopters were used to make bucket drops to slow the spread of the fire. Overnight, strong winds moved into the area. On Monday, November 28th, the exceptional drought conditions and extreme winds caused the wildfire to grow rapidly. Helicopters could not fly due to high winds and poor visibility. The National Park Service was in communication with the Gatlinburg Fire Department and the Tennessee Division of Forestry throughout the day. Winds further increased throughout the day to a sustained 40-50 mph in the evening with gusts up to 87 mph, causing numerous new wildfire starts from embers carried far in front of the main fire, as well as downed powerlines within the Gatlinburg community. The wildfire was determined to be human-caused and under the investigation of the National Park Service, ATF, and Tennessee Bureau of Investigation. Two juveniles have been arrested for Aggravated Arson in connection with the fire.
