No indeed, Mike - probably the lowest for the whole northern part of
the island since 1967 has been 943.2 mbar at Belmullet on 17 Jan 1995,
although this event would not have been below 950 in Coleraine. But at
the very tail end of 1966 this would certainly have been the case: I
suspect Monday's storm, on what looks to be a similar track, will not
surpass these values -

1 December 1966
A series of fast-moving and rapidly-deepening depressions crossed
northern Britain from the west during late November 1966. One
depression formed as an open wave 1002 mbar at 56„a N, 35„a W at noon on
30 November then deepened rapidly while moving quickly eastwards to be
located near 57„a N, 18„a W just 12 hours later, with central pressure
955 mbar. It subsequently moved more slowly east-south-eastwards
across northern Ireland and southern Scotland into the central North
Sea by 0600 GMT 2 December. The lowest barometric pressures reported
were 942.6 mbar at Carrigans (near Derry/Londonderry) and 943.9 mbar
at Belfast/Aldergrove Airport (both at 1500 GMT on 1 December) and
944.3 mbar at the Mull of Galloway at 1800 GMT. The barometric
pressure on this occasion remains the lowest on post-war record for
Northern Ireland, southern Scotland south of the Great Glen and for
all of northern England north of a line Manchester to Hull.
