    I think it might be upgraded to an EF5 at parts of the track. I saw a photo of a vehicle lift that was ripped out of the concrete, the anchor bolts were still attached to the feet of the lift. And the bolts looked a little bent to me. Not folded completely sideways into L, but not straight. And there was I think 6 bolts per foot.
    It had to take a lot of force to pull this thing out and knock it over.
    They take the force of vehicles vertically all day long.
    The pros will have to survey it though. It could have been something slamming into it that caused it to come out of the concrete. Or its jist not made for horizontal forces. But then you gotta ask. What giant thing was blown that hard to rip this thing out of the ground. Ignore the engendering details for a second. What actually caused this to happen assuming it was anchored properly.

    I think that a tornado should be rated based on a mixture of documented wind speed (the estimation), actual damage caused (the extent), and the overall communal impact (the severity). All these factors should be taken into account/consideration when determining the strength of a tornado; not just solely the severity/ type of damage caused.

      The issue with this is there are a lot of tornadoes that occur in quick spin ups that are not seen on radar. They can happen between scans. How do you measure something you cannot see? Plus unless the tornado is right on top of it, the further you are from a radar the higher up in the cloud you are looking. It something like 40 miles you are 8-10 feet with observation. Tornadoes happen mainly in the bottom 0-3km range.

    I think they need a better system. The Oolagah Ok. Tornado, April. 26, 1991, was two miles wide, but none of the damage was very intense. This one, doesn't appear to be more than 100 yds wide, but the damage looks like it went thru a blender. That lil sucker was INTENSE! Wide doesn't mean all that bad. Andover 1991 was the perfect merger of wide vs intensity. A rare thing.

  • @pauljs75
    @pauljs75 7 місяців тому

    I'm not sure if many public available radars have some of the filtering or mode tools available like the debris tracker. Although I think there are some things to look for if the radar has enough resolution and frame density in time-lapse mode. I'm not sure of the exact terminology, but I look for a "roller" in the return pattern. Think of it as the sign of a looser vortex that's on its side which moves horizontally with the storm. (Sometimes those are over a hundred miles long.) It's this barber pole banding or sometimes coil banding that moves with the weather pattern. If part of the rolling action is faster relative to the rest, and it gets tighter and kinked up into an S-shape, that's one of the spots to watch out for. I'd guess the speeds of circulation in the roller may be something like 40 to 100MPH aloft, but when it tightens up it's just like an ice skater doing a spin and pulling their arms in. It concentrates all that momentum and then doubles or triples what it starts with. Then if it's an option available through a website, you can do the storm-relative speed thing mentioned in the video to and using the contrast to get an idea of how strong it can be.
    If some of those things I'm picturing going on with that bit of information are correct, then calling a tornado a "twister" really is a more than apt description. It's one of those big horizontal vortices folding over into a kink and twisting up upon itself.

While most of the trees were stripped of small limbs, I saw no trees that were debarked. Debarking is a sign of f5. What I saw up close was consistent with sting 3 or weak 4.

Of all the PDS watches I was ever under, the closest damaging tornado that I ever encountered was the 2013 Washington, Illinois tornado that struck ten miles east of my location. The best you can do is have a place of shelter, and keep an eye and ear open for approaching storms. If you follow your local weather service office's website and keep abreast of radar images and reports of severe weather, you can have an hour or more advance notice that something bad is heading your way. If you don't have a shelter, and know that a strong, damaging tornado is approaching your area, go to someone who does have a strong shelter or evacuate the area.

      No, that's logistically impossible. But Tornado Emergencies should have been issued, especially for Greenfield. And they were not. There are also not enough tornado shelters and that's a massive understatement. And the ones that are in place are often in horrible condition. I'm a storm spotter for the NWS and I was in Cedar Rapids this day. We got the end of the severe weather event and sirens only went off once for 70+ winds. They were going for practically 3 minutes. That's it. This was after Greenfield. And emergency management decided 3 minutes was enough. The storm hit about 5 minutes later, after the sirens shut off. And they never came back on. Fortunately - we didn't get hit by a tornado.

I actually thought a tornado was coming at me. The roar sounded like the sound effect used for the thrusters of the original battlestar _Galactica._ This rumbling roar was combined with a buzzing/hissing sound that put me in mind of having your ear next to the hose end of a running vacuum cleaner. I was outside my basement looking to the southwest expecting to see power flashes and debris from an approaching tornado. But one never came.

    SIRACH 39:32 Therefore from the beginning I have been resolved, and thought upon these things, and left it in writing:
    SIRACH 39:33 The works of YHWH are all tov, and HE will supply every needful thing in due season.
    SIRACH 39:34 And no one can say, "This is worse than that," for all things shall all be well approved in their season.
    SIRACH 39:35 So therefore praise you YHWH with your whole heart and voice, and bless the NAME of YHWH(Jahweh).
    MIKAH - MICAH 3:10
    10 They build up Zion with blood, and Yerusalem with injustice.
    MIKAH - MICAH 3:12
    12 Therefore shall Zion for your sake be plowed as a field, and Yerusalem shall become heaps, and the mountain of the house as the bamah of the forest.
