The National Weather Service has confirmed that an EF1 tornado on Signal Mountain was the cause of the path of damage during Monday's storm.
Investigators surveyed the damage this afternoon and said the tornado had wind speeds of roughly 90 mph and was 50 to 60 yards wide, said Tim Troutman, a warning coordination meteorologist from the National Weather Service in Morristown, Tenn.
The storm carved a path of snapped trees and downed power lines before it "dropped" and then reformed near Red Bank High School. Because of that break, the weather service has determined that the funnels were two separate tornadoes, Troutman said.
EPB reported today that roughly 3,000 customers still were without power, but that all should have power restored by Thursday. This Signal Mountain tornado was the third confirmed funnel that spun from Monday's heavy thunderstorms. There was the tornado in Red Bank and one recorded in Marion County.
