May 20th Tornado — Moore, Oklahoma
This is a video of the tornado starting in a town called Newcastle, OK - which is just south of Moore, OK. It gives a pretty good idea of how these powerful storms start and gain so much momentum.
I have not personally vet this video for its credibility, but Charles Cook has post one video to Youtube and this is it.
The last info I saw on the news from this storm is that it was on the ground for about 40 minutes, with a debris diameter of ~2 miles wide and wind speeds upwards of 200+mph. The cursory categorization is an F4 (scale info: http://en.wikipedia.org/wiki/Fujita_scale), but they still may upgrade that after they finalize the investigation.
I grew up in Moore, OK and was around (in Norman, OK at University of Oklahoma) for the very big and destructive May 3rd, 1999 tornado. These storms are amazing, but also tragic when they rip through populated areas.
My heart and thoughts go out to all those who’ve been impacted by this tornado. Love to all my Moore Oklahomies.
