Isopycnic Posted May 31, 2012 Share Posted May 31, 2012 Probably been posted already, and will be posted 10 times more today but: Fifty-six years of Tornado tracks - map http://uxblog.idvsolutions.com/2012/05/tornado-tracks.html Got this data from NOAA via the spectacular Data.gov. It tracks 56 years of tornado paths along with a host of attribute information. Here, the tracks are categorized by their F-Scale (which isn't the latest and greatest means but good enough for a hack like me), where brighter strokes represent more violent storms. The Map, LARGE!!!! http://visually.visually.netdna-cdn.com/TornadoTracks_4fbd458d255c5.jpg Link to comment Share on other sites More sharing options...
mappy Posted May 31, 2012 Share Posted May 31, 2012 Horrible map in my opinion. Incredibly difficult to tell The difference between ratings. Link to comment Share on other sites More sharing options...
Ed Lizard Posted May 31, 2012 Share Posted May 31, 2012 Scale is hard to red- BTW, there was a tornado that crossed Florida Gulf to Atlantic? Link to comment Share on other sites More sharing options...

Ed Lizard Posted May 31, 2012 Share Posted May 31, 2012 Yup - was an EF4 http://www.tornadohi.../custom/1392398 That would have been ugly a few years later when Walt Disney World was open. Link to comment Share on other sites More sharing options...
isohume Posted May 31, 2012 Share Posted May 31, 2012 Neato Jivey! Kinda where you'd think they'd be, but far-out anyway. Link to comment Share on other sites More sharing options...
klw Posted May 31, 2012 Share Posted May 31, 2012 Interesting but I think there is a goof unless a tornado really did travel (south to north?) 75 miles through the CT River valley of VT. Link to comment Share on other sites More sharing options...

Hard to say - you can go to tornadohistoryproject.com and search VT tornadoes I will say, since I have worked with the SPC data (which is what this guy used to make this map) there are a lot of errors within their lat/long coordinates, particularly their track information, starting points, and ending points.

mappy Posted May 31, 2012 Share Posted May 31, 2012 The long track in Vermont doesn't show up at tornadohistoryproject.com Nope. It wouldn't. Upon further examination, the tornado is being listed under New Hampshire data, not Vermont (starting point is in NH) http://www.tornadohistoryproject.com/custom/1394529 Link to comment Share on other sites More sharing options...
mappy Posted May 31, 2012 Share Posted May 31, 2012 Its obvious something is wrong with that particular track - the information on THP has it listed as being only 8 miles long, but when measured out its closer to 70 miles (from start to finish). Again, SPC seems to have a lot of issues with their lat/long coordinates Link to comment Share on other sites More sharing options...
GaWx Posted May 31, 2012 Share Posted May 31, 2012 I'm suspicious that this map doesn't include all tornadoes because I see not more than perhaps one moving W or NW from the ocean in the coastal sections just east of Savannah. I recall at least a few low intensity tornadoes in recent years doing just that as the result of tropical cyclones. Maybe it is hard to see due to the way the map is presented. It shows quite well how hard N and C MS as well as N AL have been hit. Link to comment Share on other sites More sharing options...
New England Storm Posted May 31, 2012 Share Posted May 31, 2012 The map is cool, no doubt about it. Kinda hard to read in regard to f/ef scale however. Link to comment Share on other sites More sharing options...

isohume Posted May 31, 2012 Share Posted May 31, 2012 Were they ones with just a touchdown point? No they had tracks...short lived, but not included in SPC's map. Link to comment Share on other sites More sharing options...
mappy Posted May 31, 2012 Share Posted May 31, 2012 No they had tracks...short lived, but not included in SPC's map. Ah ok. I've noticed that some with only a brief touchdown aren't included in SPCs tracks file they have available for download Link to comment Share on other sites More sharing options...
isohume Posted May 31, 2012 Share Posted May 31, 2012 Ah ok.

isohume Posted May 31, 2012 Share Posted May 31, 2012 Hence why I said SPC and not your local database Oh I know, I was just saying that was probably the reason they aren't showing up. Link to comment Share on other sites More sharing options...
eekuasepinniW Posted May 31, 2012 Share Posted May 31, 2012 http://www.tornadohi...o/20040813.33.1 I have an unobstructed view and was outside during that storm as it passed by 1 mile away. Saw nothing out of the ordinary and there was no tree damage where it crossed route 3. I would have assumed it was a bogus report if it wasn't for a single photo of a swirl crossing Lake Winnipesaukee. Even F0 seems generous. /csb Link to comment Share on other sites More sharing options...
