Default Low pressure mid-North Atlantic


.... the Exeter/EGRR PROG VT 26/1200Z here ...

[accessed 25/1935Z]

has central pressure in mid-North Atlantic down to 928 mbar. We'd have
to get down to the realms of 916-ish mbar for 'record-breakers', but
anything below 930 is still in the 'interesting' category: I don't have
a detailed database of these, but Stephen Burt who has made an extensive
study of such has noted a similar figure (i.e. 928 mbar) in March of
2003 (8th).

It is a *forecast* of course so it will be interesting to see what the
actual value comes out as. Sometimes the models over-cook these things
for various reasons - the UK NAE used to have a latent-heat exchange
problem in this respect but not sure if this is still the case.
