A Cold front moving north combined with unusually warm moist air to make the perfect environment for Storms. However, only one tornado touched down being the Anchorage EF-5. There was only a MRGL risk that day at 10%. At 1:00 PM, however one hour before it was upped to a 20% chance of severe storms. The circumstances were perfect for an EF-5 in Alaska with many doubting it will ever happen again. Wind speeds were estimated as high as 267 MPH.
At around 1:30 PM a round of storms were heading south towards Anchorage Alaska. At 2:10 They increased to supercell status. at 2:30 a quarter mile wide funnel was spotted on the outskirts of Anchorage. It touched down at EF-3 strength, shredding trees and eventually hitting the outer areas of Anchorage. A gas station was destroyed as it strengthened into a Low end EF-4. Homes were swept away, before it strengthened into a High end EF-5. Cars were ripped and twisted like toys. Houses were lifted off the ground and foundations were cracked and even torn. An 8 inch scouring was observed in the grass with pavement being ripped off the road. It hit a small airport, tossing planes everywhere, including a Cessina which was found 3 miles away. An Amazon storage facility was leveled with products going flying everywhere. The three schools were also blown away, killing everyone inside the high school. A Chevrolet and Ford dealer both had all their cars turned inside out and shot at other buildings. The tornado weakened into a low end EF-5 but it still destroyed a Walmart Neighborhood Market and threw Semi's like toys, smashing homes. It weakened more to high end EF-3 status. It tore up some Drilling Rigs and carried a tractor 1 mile before dropping it. The tornado weakened more until it roped out but not before damaging a farmhouse, by ripping off its roof and finally dissipating.
After the tornado, many fires were observed along with thousands of injuries. Anchorage declared a state of emergency as the fires destroyed overall, 1654 homes. 5,897 people died and 5.5 billion was done in damages. Anchorage still hasn't fully recovered today.
