This photo was posted on the Hayden, Alabama News Facebook page, apparently taken from SW Blount County just west of I-65 looking toward Warrior. I had no idea this tornado was so close to the ground. I'm not sure if it ever touched down anywhere in North Jefferson or Blount Counties? I wasn't reading the forum feed just before this warning was issued, but when I scrolled back through, I noticed people mentioning that this storm needed a warning. We had a very brief heads up and had to get into the basement really quickly. The weather radio alerted us immediately; none of the apps I have installed alerted us for at least a few more minutes after the radio. I'm convinced the old-school weather radios are essential, even though they can be annoying when they blast in the middle of the night for a warning on the other side of the county.

We have several. They'll wake you up every time, that's for sure.

More clear view of Greensboro shows that the two slabs in the middle of the first pic likely not typical FR12 type of thing and all these structure showed on this picture was not on the tornado's center line. The first pic also shows that not only debris from house, but also branches from the trees were cut into match-sticking things tossed along the center line of the tornado.Tornado had a really well defined center line all the way down to the forest. Tornados with such impressive couplet as well as such well defined small core with very high level debirs granulation remind me some very famous violent tornados in the past. These types of tornados are rare and usually can have very high ceiling. Very fortunately it seems that not many houses(or no house)stand in the core of the tornado's path at its likely peak intensity.

If we are going to assume the homes that once stood on the empty foundations were similar to the two blue homes visible to the right of them, the homes were likely not well-constructed and the damage likely wouldn't warrant an EF5 (maybe not even an EF4) rating. The wind rowing, granulation of debris and tree damage are all very impressive however.

If these houses have some anchoring flaws or weren't built with standard materials, which may prevent a higher than EF3 rating, the biggest likelihood to get an EF4 rating is based on those extreme hardwood tree damage.But I do wonder have BMX ever rated a tornado just based on tree damage? I remember there're some 165mph damage points in the hardest-hit wood area in Beauregard like the one below.

BMX wasn't so conservative or inadvertent when it comes to tornado rating like other NWS(Yeah we all know which one/several NWS I'm referring to), but they do comply with the EF system very carefully, and sometimes, strictly, so I won't fully count on they'll rate the tornado EF4 JUST BASED ON tree damage. Of course, Greensboro's tree damage severity wasn't the same level as Bassfield or other high-end EF4s, so the necessity to rate it as an EF4 just because of its tree damage while ignoring other damage indicators doesn't really exist.So let's see how BMX will handle this

The Upper Bound of hardwood tree damage just stopped at 167mph, so when it comes to rating numerous debarked hardwood tree damage, different WFOs tend to have different rating styles and some of them have been pretty subjective.
Beauregard 165mph

Bassfield 167mph

Bassfield(near Seminary) 167mph
Max out said some of the surveyors, one of the strongest tree damage ever seen in JAX

According to that thread, since the land that the radome sits on is now privately owned, it'll be up to the landowner to decide what to do with it.

(Personally, I've been having thoughts for several years now of having a research radar of some kind replace the old WSR-57; it could help aid in severe weather research in Dixie Alley if that were to be done. Perhaps we should start a petition or something to do just that...)

Here's video of the Greensboro tornado from highway 14. The video is muted due to some very tense moments that I do not wish to experience again. You can see trees in the sky to our side and in front of us right before we turned around.

Matt thank you for sharing. Curious did you just lose track of where the tornado was at due to the terrain and hard to see?

Radar feed went out and the road turned from SSE to ESE and we weren't gaining any ground on being able to cross the path. It cut us off. Honestly in the first part of the video I wasn't sure it was on the ground because of how large it was. There was no TDS showing up.

According to wiki the Newnan tornado path width was 1,850 yards and path length was 38.88 miles. That is incredible if true. It probably would be one of the widest tornadoes recorded in Georgia as well.
Edit: The widest tornado I could find in Georgia was an EF3 and 2200 yards wide. It happened on January 22, 2017.

What do y’all think the brent tornado will be rated?
I'd honestly be surprised if it was rated above EF3, just because none of the damage pictures that have come out have looked like they meet the criteria for a higher category. It was almost certainly a violent tornado, but fortunately it spent most of its life over sparsely populated areas. I'm fine with a tornado being "underrated" because it didn't hit anything.
