Down thread someone lists the average tornado warning time as 9 minutes. With 9 minutes warning, most people would be just getting to their cars with some still on the plant floor getting their stuff to go home. They had 20 minutes per the article, in that time frame you would have a traffic jam in the parking lot as everyone tried to leave down the 2 lane road that services the factory.

Playing fast and loose here with warning definitions. They had 2 days warning. not 20 minutes.

  They had 2 day warning that the weather system was likely to produce tornadoes. Comment say that Mayfield had about 2.5 hours of warning based on this blog: https://cliffmass.blogspot.com/2021/12/a-critical-gap-in-tornado-warning.html?m=1 https://cliffmass.blogspot.com/2021/12/a-critical-gap-in-tor... If you look at the area encompassed by the tornado watch, should they have evacuated it in it's entirety? https://blogger.googleusercontent.com/img/a/AVvXsEji0sqQJqWoAwe9rODyi4NfOkGdcAHwXrqG4WGlX9S22VZp_kKQI3vx2yrVAvI8MCmyVE6bGUALREgpMLo8pEyfw6PWhpjWawDLhWNnhMphquNc_i6wL-G_6NucN0fxTmxGubmBwQP1YjA8syn2mQcOPCf6L55zMTxxzMCdPB_0fPuLOpC6fOtssQA0=s1140 https://blogger.googleusercontent.com/img/a/AVvXsEji0sqQJqWo... Look about 300mi x 170mi area. If you take Jones burro as the center, its 120mi to the edge, technically if everyone could evacuate at 60mph you could get everyone out in 2 hours.... but with NWS tornado warnings have a False Alarm Rate (FAR) of roughly 70% you probably won't get that many people to evacuate at all unless you make it mandatory. Then it will take much longer than 2 hours to get people out. You are talking about massive areas with small amounts of time: https://blogger.googleusercontent.com/img/a/AVvXsEhcPxy7gbyruPRvRpRf3x7zQ4ZaUWhAmVIcMzQSB1GHP4WictUICuT8R3OyM2Bc1S2QNAM1D2w0x4NyYaYMQEfFMUqXekRbN9L4RAl4OctlijmXFxvMK1ho-Us3eqJaEz9OAmNpDvTB4KjPkO7HkBfgBKr9LR0oF7f5X6492SQuO9aF_a0129710lpM=s1020 https://blogger.googleusercontent.com/img/a/AVvXsEhcPxy7gbyr... is roughly 430 square miles for something that is small and fast moving.

    What? I'm not talking about evacuating people... I'm talking about not forcing them to come in to work for a 3rd shift overnight run that can most definitely be delayed by a shift for a weather pattern known to create high numbers of tornadoes.

    As that comment corrected that was more like 20 min (time zone wise)
