Lowest pressure ever recorded in a tornado

[Chris Lott]

I have seen lots of stories on this, and even the documentary when National Geographic was with Tim Samaras on this chase, but I had no idea he made the Guinness book of World Records for it! Pretty cool, Tim.

There have only been a handful over reliable pressure measurements in a tornado, most of which have been courtesy of Samaras and his turtles.

Wow Tim. This is very revered. Great work.

Nice job Tim!
100mb of pressure drop: so it means that the pressure inside of the tornado fell down to nearly 800-850mb..It could be inteesting to know the real value of the pressure inside.

We should encourage everybody to put a barometer (and a flashlight) in his/her storm shelter, with instructions to note the initial, minimum, and post storm pressure. That ought to produce some data and perhaps a new record or two. It will also let the occupants know when it is safe to come out (after the pressure has gone back up).
