Here's the additional Damage Point text from the Enderlin EF-5 survey:

-33 train cars derailed
-19 fully loaded grain hopper cars
-1 fully loaded grain car and 4 tankers pulled away
-empty tanker thrown 145m
-train cars thrown 2x farther than EF-5 threshold
-train cars were 4x heavier than models

Tipped loaded car: The tornado derailed 33 train cars including 19 fully-loaded grain hopper cars and 14 empty tanker cars, mainly tipped from the track. Included in the derailed cars were one filled grain car (~286,000 lbs) and four empty tanker cars (~72,000 lbs) that were pulled into a field away from the track. One of the 4 tanker cars was tossed 600-1000 ft (183-305 m) from the track and an estimated 475.7 ft (145 m) from the distance of the previous tanker car it was attached to before being pulled off of the track; wheel sets detached near the point from which the cars were derailed from the track. It was in this train derailment location that EF-5 damage intensity was noted with greater than 210 mph winds listed officially for this tornado. Extensive collaboration with wind damage experts provided forensic analyses for the train damage that occurred with this tornado. These analyses estimate potential wind speeds of approximately 230 mph are needed to completely overturn a fully loaded grain hopper car. Collaboration with the Northern Tornadoes Project at Western University’s Canadian Severe Storms Laboratory estimated a potential wind speed of >119 m/s (>266 mph) to loft the empty tanker car 475.7 ft (145 m) using similar calculations performed in Estimating Wind Speeds in Tornadoes Using Debris Trajectories of Large Compact Objects (Miller et al. 2024). The study, published in the Monthly Weather Review, found that large compact objects lofted greater than 50 m indicate EF-5 intensity winds (greater than 200 mph). The Enderlin train cars were nearly 2× farther than the EF-5 threshold distance and ~4× heavier than the heaviest object modeled in the study.

Thanks to @drkimwood.bsky.social for making this graphic of #Helene.

What I find interesting is that it wasn't in Southern Appalachia for that long. But the predecessor rainfall event that came before Helene was the 1-2 punch that brought devastation to the area.

There are actually very few people with the title "Climate Scientist"... But there are many of us who identify as part of that community. Gotta say having my community classified as "Evil" by the head of state of my county is a first for me... A chilling first. www.nytimes.com/2025/09/23/u...

in light of the kimmel news, just a reminder that a few days ago a prominent fox news host literally called for killing homeless people. right afterward, someone shot up a couple homeless encampments.

that fox news host still has his job.
