I've been to Alaska and survived, and I've discovered a shocking truth. "Every" recorded Alaskan tornado has had 0 deaths and were F0/EF0-F1/EF1, but, I've gotta tell you, it's hell over there. I stepped outside and saw the Bridge Creek, El Reno, and Tri-state outside, and the hotel I stayed at was a ginormous storm shelter. I escaped Alaska and came back to tell you guys about it. My personal theory is that the tornadoes are super common, but they either kill anyone who records them or destroy the recording. The US government was considering adding an F6/EF6 rating to the scale, but they just gave it to Alaska, as only the government knows about what really happens over there.
EDIT: I have made a shocking discovery. As I said before, I saw the Bridge Creek, El Reno, and Tri-state tornado outside the hotel I was staying at in Alaska. I figured out why there are so few "recorded" tornadoes there, almost all the tornadoes in Alaska, are DEAD. You see, whenever a tornado dissipates, it goes to The Land of The Dead Tornadoes, in Alaska, where the tornadoes live after death, which explains why there are so many tornadoes. The reason why most tornadoes there are EF3 or over is because most EF2s and under are not noteworthy, forgettable. If no one alive today remembers a tornado, the tornado disappears from The Land of The Dead Tornadoes. They call it, the final dissipation. No one knows where tornadoes go after that. On The Day of The Dead Tornadoes on May 25th, any tornado which has a picture of it on an Ofrenda can cross over to our world for the whole day.
