According to Krissy Hurley, the meteorologist in charge at the National Weather Service in Nashville, the survey team found very minimal damage from the two EF-0 tornadoes.
“One with 70-mile-per-hour winds and another one with 75-mile-per-hour winds,” Hurley said. “With these tornadoes, it was very apparent that these tornadoes were elevated with a lot of damage to treetops and minimal structure damage, mostly to outbuildings and barns.”
The first tornado dropped down in southern Cumberland County at 6:21 p.m. Saturday, Aug. 1, and the second one touched down in Fentress County about 10 minutes later.
These two tornadoes occurred in what is known as a radar hole. A radar hole is an area that is far from the nearest radar. By the time the radar beam gets there, it is thousands of feet above the ground. This means the rotation caused by a tornado can go completely under the radar. The curvature of the Earth and the slight angle of the radar beam are why it gets high above the ground.
According to Hurley, even if there was a radar nearby, these two tornadoes still could have gone unnoticed because they were so short-lived…
