“We woke up to the sound of a freight train,” said one survivor of the early morning tornado of March 3, 2020. “Super Tuesday” primary voting day in Nashville, Tennessee. In a period of about three hours, the Tennessee Tornado 2020 struck by at least six tornadoes, three rated EF-3 strength, two EF-2, and an EF-1. An EF-2 tornado completely removes the roof of a well-built house. EF-3s remove the roof and knock down some, but not all, walls. The state is counting two-dozen dead, with many more hospitalized.As a meteorologist here in Tornado Alley, let me state unequivocally: No one should be alerted to a tornado’s arrival by the sound of a freight train. Every home in America should be using NOAA Weather Radio, the indoor tornado siren. These devices were specifically designed to save lives in nocturnal tornadoes. By Public Alert certification, they are required to have a 76-decibel alert tone that makes sure you’re awakened not by the sound of the tornado, but by the National Weather Service telling you to seek shelter…immediately.
