*IndyMeso* Posted March 8, 2012 Share Posted March 8, 2012 Here it is from cnn eyewall. I haven't been able to find the full unedited version yet but he was close! That is also the one that I saw. This gas station is now fully functional I believe and for the most part the only thing they had to fix was their sign and the power. Meanwhile, across the street, semis and equipment trucks were tossed like toys. Link to comment Share on other sites More sharing options...
Hoosier Posted March 8, 2012 Share Posted March 8, 2012 I guess I should clarify my original guess about the winds. I think the winds were probably less than 70 mph during much of the video but it looked like there were some pretty strong gusts. Link to comment Share on other sites More sharing options...

I think the winds were probably less than 70 mph during much of the video but it looked like there were some pretty strong gusts. Yeah, that's what I was going with. We're in agreement that the highest gusts were from inflow/periphery winds. Although, if you go off of the NWS Louisville map, a new vortex developed essentially right over them.

HurricaneJosh Posted March 8, 2012 Share Posted March 8, 2012 The tree to his right has a couple sizeable branches snapped off and that giant shed, which looks almost like a small house, has very noticeable damage done to it. That large tree, probably an oak, had some pretty violent motion in those gusts. As someone said above, part of it broke and it had already been knocked off balance a bit before it fell, it just did the gradual large, old growth tree slow tumble. 70-85 is likely a good estimation. I think you're overestimating. Those kinds of effects are all things that happen in a solid gale. I'll admit I generally estimate conservatively-- but I just don't think the winds were that high on the guy's lawn, in the foreground, during the time that the video is rolling. (Maybe stronger winds happened before he started shooting.) Across the lawn and beyond was a very different story. Like I said, winds looked much higher across the way.

Yeah, I was judging the massive oak tree, what it experienced. The house itself probably saw 60 at most. It is astounding at how much variation winds can be in as little as 50 yards considering a tornado of this magnitude. Link to comment Share on other sites More sharing options...

The winds even on the other side of the lawn are way stronger. Link to comment Share on other sites More sharing options...

Hope they analyse this, some awesome stuff going on. I admit I watched it about 25 times so far. Link to comment Share on other sites More sharing options...
cyclone77 Posted March 8, 2012 Share Posted March 8, 2012 Just noticed something else of interest. At the very beginning of the video around the 3 second mark you can see a white lawn chair moving away from the cameraman out into the street (left side of vid). It then stops in the street and holds still for several seconds. The winds suddenly change direction and increase as the tornado goes by after that. The cameraman then pans a bit to the right losing sight of the chair, but by the 18 second mark what appears to be that chair goes hauling ass towards the tornado through the neighbors yard behind that big tree. It appears to be moving very fast and gains some altitude as well. Definitely wouldn't have wanted to get hit by that. Note there's a second white lawn chair that appears very close to the cameraman inside the fenced in area around the 12 second mark. Link to comment Share on other sites More sharing options...
nwohweather Posted March 9, 2012 Share Posted March 9, 2012 Props to him being able to stand up through that wind. It had to be gusting close to 80 the way it knocked down those trees and ripped off those shingles. Can't be easy filming conditions Link to comment Share on other sites More sharing options...

The winds where the person was standing were nowhere near 80 mph-- at least not while the camera was recording. Trees can go down and shingles can come off of roofs in winds below hurricane force.

HurricaneJosh Posted March 9, 2012 Share Posted March 9, 2012 This spectacular video of the Tuscaloosa tornado is a good example of the cameraman actually being well within the envelope of hurricane-force winds. The Henryville video is awesome, but this dude here was much closer and I'd say the winds at this cameraman's location most certainly reached hurricane force for a few moments as the funnel passed very close and the wind shifted. The really crazy part is ~1:00-1:30. Just awesome, awesome video: Link to comment Share on other sites More sharing options...
HurricaneJosh Posted March 9, 2012 Share Posted March 9, 2012 Re: wind estimations in general... This is a topic of great interest to me, given that I chase a lot and have been in the cores of many hurricanes-- and also that I have a great interest in postanalysis and data integrity. My general impression is that most folks-- even experienced chasers-- overestimate the winds they're experiencing (or see in videos) by a factor of 1.5 to 2. I've said this before, but a even a low-end Cat-1 hurricane wind (65 kt 1-min average at 10-m height) is wild and feels quite violent-- and far fewer people have experienced that than we think.

My general impression is that most folks-- even experienced chasers-- overestimate the winds they're experiencing by a factor of 1.5 to 2. I've said this before, but a true sustained wind of 65 kt is very, very strong-- and far fewer people have experienced that than we think. I think that's generally true. Although I think once you start approaching extreme wind speeds (something like 100 mph), people tend to underestimate. Then again it is very difficult to differentiate between wind speeds at that end of the spectrum. Link to comment Share on other sites More sharing options...
Wannabehippie Posted March 9, 2012 Share Posted March 9, 2012 I think it takes a lot of balls or being a tad insane to stay that close to a tornado, filming out a window as it is literally a few yards away from you.

Trees can go down and shingles can come off of roofs in winds below hurricane force. Yeah you make a good point. I was outside when a 66 mph gust front came through once(measured it on my anemometer) and was almost blown to the ground off of a porch. It is so hard to tell on a video though Link to comment Share on other sites More sharing options...

aldamon Posted March 9, 2012 Share Posted March 9, 2012 Amazing. I kept waiting for a projectile to go through the window!

AtticaFanatica Posted March 9, 2012 Share Posted March 9, 2012 At about :20, just to the right of the huge tree, something fairly sizeable, either a tree or a building debris, is shot nearly straight downward out of the funnel. The speed is insane and I can't imagine the amount of force to shoot something downward against the overall vertical motion at the speed it appears. If a tornado has multiple vortices, it likely has a central downdraft rather than a central updraft. Link to comment Share on other sites More sharing options...
icebreaker5221 Posted March 9, 2012 Share Posted March 9, 2012 I have to agree with Josh on this one. The winds where he (original vid) is standing are no more than 45 mph at the time of recording, but clearly stronger across the street. Pay attention to the small conifer tree close to the camera.

Calderon Posted March 9, 2012 Share Posted March 9, 2012 If a tornado has multiple vortices, it likely has a central downdraft rather than a central updraft. i know that much, but I've never seen a piece of debris shot downward like that. Link to comment Share on other sites More sharing options...
AtticaFanatica Posted March 10, 2012 Share Posted March 10, 2012 i know that much, but I've never seen a piece of debris shot downward like that. yeah, probably because the central downdraft is within the condensation funnel, so you usually don't see those effects Link to comment Share on other sites More sharing options...

shaggy Posted March 10, 2012 Share Posted March 10, 2012 Those are some of the best videos I have seen. Those may end up being very helpful with research also. So many things going on in those videos that shed light on what happens in and around a tornado. Seems the winds were actually stronger after the tornado had passed by some distance and when the house in the back loses its roof you never see a funnel so how far were they from the actual tornado? If they weren't struck by the actual funnel itself is their damage tornado damage or some other classification? Link to comment Share on other sites More sharing options...
WxFreak11 Posted March 10, 2012 Share Posted March 10, 2012 That family's survellance video is one of the best tornado videos ever. It's probably the closest thing to actually having experienced it..minus the terror of course. Link to comment Share on other sites More sharing options...
