I know i'm late with this, but i am just totally shocked that hurricane
Wilma reached a lower pressure than Gilbert's 888 mb in 1988. Wilma
hit 882 mb! - i never thought what was a tropical depression a few
days ago, late in the season, would smash Gilbert's pressure record.
un****ingbelievable.



And, to have a comparison, what's the pressure inside a tornado ? i.e. in
the eye of a twister ? Is it negative ?


As far as I recall, pressure inside a tornado vortex has
not yet been measured, but the estimates I recall reading
about several years ago were down around 900 mb.


Tim Samaras got a pressure-measuring probe into the Manchester, SD
tornado in 2003 and got a pressure drop of ~100 mb in about 10 seconds
as the tornado passed over the probe.
