AtticaFanatica Posted May 12, 2011 Share Posted May 12, 2011 How many tornadoes occurred on 4-27? Some number that can't be verified. Link to comment Share on other sites More sharing options...
tornadotony Posted May 13, 2011 Author Share Posted May 13, 2011 Some number that can't be verified. Yeah, many (if not most events) have discrepancies between surveys and reality. This is one where it's definitely inevitable. What's so staggering is HOW HARD the main outbreak area was effected. To have as many tornadoes as with had with 70mi+ path lengths is astonishing.

In addition, didnt like a dozen of those tornadoes have damage paths at least a mile-wide. Link to comment Share on other sites More sharing options...
knuckle66 Posted May 13, 2011 Share Posted May 13, 2011 ALABAMA F4/EF4 AND F5/EF5 TORNADOES*: TIME PERIOD F4 OR EF4 F5 OR EF5 SINCE 1874 64 6 SINCE 1950 32 6 APRIL 27, 2011 7 2 (CORRECTED NUMBER) *BASED ON MAXIMUM EF RATING ALONG THE ENTIRE TRACK. --------------- LIST OF ALABAMA F5/EF5 TORNADOES: MARCH 3, 1966 - VIENNA-BENOVALA (PICKENS, TUSCALOOSA) APRIL 3, 1974 - MOULTON (LAWRENCE, LIMESTONE, MORGAN, MADISON) APRIL 3, 1974 - ATHENS-VANNTOWN (LIMESTONE, MADISON, LINCOLN TN) APRIL 3, 1974 - GUIN (LAMAR, MARION, WINSTON, LAWRENCE, MORGAN) APRIL 4, 1977 - SMITHFIELD (JEFFERSON) (CORRECTED) APRIL 8, 1998 - OAK GROVE (TUSCALOOSA, JEFFERSON) APRIL 27, 2011 - SMITHVILLE, MS - SHOTTSVILLE, AL (MARION, FRANKLIN) APRIL 27, 2011 - HACKLEBURG (MARION, FRANKLIN, LAWRENCE, MORGAN, LIMESTONE, MADISON) Can someone explain how they list 2 F5/EF5 tornadoes when there was only 1 (Hackleburg) EF5 in Alabama? The Shottsville, AL was rated an EF3 but the Smithville EF5 damage was in MS. Two different WFOs but two different states. Link to comment Share on other sites More sharing options...

The Shottsville, AL was rated an EF3 but the Smithville EF5 damage was in MS. Two different WFOs but two different states. Simple, even though the damage rated in separate CWAs is different, it is the same tornado and the path is given the maximum rating found along the entire damage track. Also, with this event, Alabama now regains the "lead" for the state with most F5 tornadoes. Link to comment Share on other sites More sharing options...

What's so staggering is HOW HARD the main outbreak area was effected. To have as many tornadoes as with had with 70mi+ path lengths is astonishing. Sure, but it'd be nice to have a number even if we know it's wrong. Is it safe to say that there were more than 148 on April 27? Link to comment Share on other sites More sharing options...
AtticaFanatica Posted May 13, 2011 Share Posted May 13, 2011 Sure, but it'd be nice to have a number even if we know it's wrong. I guess, as long as it's not used incorrectly as if there are no error bars attached. Link to comment Share on other sites More sharing options...
Master of Disaster Posted May 13, 2011 Share Posted May 13, 2011 Also, with this event, Alabama now regains the "lead" for the state with most F5 tornadoes. Kind of a sad but interesting little note there. I bet most people would assume it was Kansas or Oklahoma. Link to comment Share on other sites More sharing options...

Also, with this event, Alabama now regains the "lead" for the state with most F5 tornadoes. This makes sense and it is how I would consider things. It is, however, inconsistent with how they have reported the last F5/EF-5 in Mississippi having been in 1966. In 1971, Louisiana's lone F5 crossed into Mississippi. In fact, the vast majority of the path was in Mississippi. The F5 damage was rated in Louisiana, not in Mississippi which is why they deferred to 1966 as having been Mississippi's last F5.

Just like the Winn Parish EF4 tornado on November 29, 2010. NWS in Shreveport listed the last F4/EF4 tornado was tornado in 1999 but I thought the Yazoo City EF4 tornado on April 24, 2010 would be. They told me it was because the Yazoo City tornado did EF4 damage in Mississippi and not in Louisiana. I thought a tornado was rated based on the highest damage point during the entire track.

cyclone77 Posted May 16, 2011 Share Posted May 16, 2011 That is one incredible video. The cameraman was crazy, but I'm glad he shot it lol. Just shows how ferocious that thing was when you see it from so close like that. The winds were probably over 100mph right outside his door there. Probably didn't have to go too far from his location to hit some very serious damage. Link to comment Share on other sites More sharing options...
Calderon Posted May 17, 2011 Share Posted May 17, 2011 this video alone needs it's own thread. I've watched it over and over, analyzing little details. So fascinating to watch the finer parts of a violent tornado in action at close range. Link to comment Share on other sites More sharing options...

Someone mentioned what looks like a car door in the power lines towards the end of the video as he pans towards the right. I paused it and it kind of does look like a car door. You can also see the large tower in the distance fall in the first minute of the video. It's fascinating to see how quickly the winds change direction as the tornado passes. It looks like the edge of the condensation brushes over the building across the street. Very surprised it didn't lose the roof. It had to be close to letting go.

Also at 1:08 the 2nd window in the green van gets busted by debris. The more I watch, the more I notice. Link to comment Share on other sites More sharing options...

It looks like there's some small vorticies spinning in the parking lot area starting just after the 1:00 mark. Might just be wind eddies between the buildings, but some of them seem to be spinning pretty quickly. Another thing I've noticed is the very heavy rain that's falling just before and during the passing of the tornado. That means the rain wrapped all the way around the north and northwest side of the tornado. I figured the rain wouldn't wrap around that far, but apparently it did.

cyclone77 Posted May 17, 2011 Share Posted May 17, 2011 At 1:16 something very large lands right behind the trees directly across the street behind the building. It was probably a roof, or part of a roof off something. Link to comment Share on other sites More sharing options...
cyclone77 Posted May 17, 2011 Share Posted May 17, 2011 Don't know if you guys saw this one yet, but here's another one in spanish. The tornado barely misses them, but not as close as the above video. They get hit with some powerful RFD that takes down a tree though. Link to comment Share on other sites More sharing options...
thewxmann Posted May 17, 2011 Share Posted May 17, 2011 The Duarte video might be one of the best of a violent tornado I've ever seen. Also may be one of the closest videos of a violent tornado ever filmed. Link to comment Share on other sites More sharing options...
cyclone77 Posted May 17, 2011 Share Posted May 17, 2011 The Duarte video must have been shot very close to the Charleston Square apartments. In the Charleston Square video you can see the same large high flying piece of debris as you see in this video at 0:35. The angle and distance is nearly the same as well. I'm guessing the Charleston Square apartments were probably just south of this location. Link to comment Share on other sites More sharing options...
Calderon Posted May 17, 2011 Share Posted May 17, 2011 I've pinpointed the Duarte video location. It is on a small cul-de-cas between 25th and 27th Streets directly behind the Nat'l Guard Armory, literally the property adjacent to the NW corner of Charleston Square and across the street to the NE of the Rosedale housing project. The tower seen taken out at 0:43 seconds is located directly beside the NB lanes of I-359 between 29th and 30th Streets. Link to comment Share on other sites More sharing options...
BadgerWXman Posted May 17, 2011 Share Posted May 17, 2011 Are you kidding me with some of the videos coming out from that day?? These are absurdly awesome and the people filming them are absurdly stupid! Either way, gotta give them credit for their bravery I guess. Link to comment Share on other sites More sharing options...
aslkahuna Posted May 17, 2011 Share Posted May 17, 2011 The Duarte video might be one of the best of a violent tornado I've ever seen. Also may be one of the closest videos of a violent tornado ever filmed. I think the closest video ever filmed in a non chase was the one in Texas back in the 1990's.

cyclone77 Posted May 17, 2011 Share Posted May 17, 2011 I think one of the most amazing aspects of the Durate video is the sound of the tornado. When he steps out around the 0:50 mark it's insanely loud. The tornado was still a little ways away at that point too. After that he goes back inside and the roar is still insanely loud as the tornado passes by. Hearing how loud it was when he was outside around the 0:50 mark, and how loud it is from INSIDE after the 1:00 minute mark, I can only imagine what that would have sounded like if he had stayed just outside his door. I think the only sound in nature that comes close to sounding as intimidating as that would maybe be a roar from a lion LOL. Link to comment Share on other sites More sharing options...
gymengineer Posted May 18, 2011 Share Posted May 18, 2011 http://www.spc.noaa.gov/climo/torn/fataltorn.html The death toll of the Marion County to Madison County F5 tornado is up to 78. The Tuscaloosa/Birmingham tornado death toll is up to 61. ..still amazing to think about two well-warned (not like Plainfield, IL) tornados causing over 50 deaths on the same day. That Hackleburg-Phil Campbell tornado did not even pass through a densely populated urban corridor like the Tuscaloosa/Jefferson County one, and with several swaths of F5 damage, it must be considered one of the most fearsome tornados in US history.
