lots of snips

Using George's rule, Martin, with today's midday 500mb data to the
east of Newfoundland from the Uni of Wyoming site, the maximum
deepening I could get from the nomogram was 35mb in the next 24 hours.
The UK Met.O 1200Z synoptic had the central pressure at 967mb, so this
would give 932mb for 1200Z Saturday.

.... at 12Z, it's looking around 938 mbar (from meteocentre.com site), so
it might be 1-0 in favour of JJ George and R Lovett!

We'll have to wait to see the various 'official' analyses of course and
it may not have finished deepening: the 'rule' tried to predict maximum
deepening rather than spot time central pressure values, so the 932
might be quite near the mark.
