There were plenty of showers and a few thunderstorms during the afternoon with local flash flooding in places.
WV imagery indicated that vorticity advection forcing was present with the strongest bands of wet weather across CS England
and especially across the West Midlands and NW England. Showers were generated inland but eventually died out as the
next system moved to the SW UK. There were gusts
to 69kt at South Uist (Western Isles) and also some widespread power failures across Northern Ireland. There were also strong winds in the far SW with 60kt being recorded
at St Mary's on the Isles of Scilly. Falmouth reported a mean wind at 18Z of 60kt at Pendennis Castle -
a very exposed spot in a SSWly. Offshore there was a gust of 70knots at the Seven Stones lightship at 18Z,
just over 80 mph.
Ireland was badly affected in particular. Electricity
crews worked flat out to restore supply to about 40,000 homes around Wexford, Kildare, Longford, Mullingar in Co
Westmeath and north Dublin. Parts of Bray in Co Wicklow and Shankill in south Dublin were also affected. Train services were
suspended for a time around Dublin and roads in Kildare and Galway were blocked by fallen trees. There was also
severe flooding in Cavan and Monaghan as a result of heavy rainfall. Premises near Castleblayney were affected
with more serious flooding reported in the Clones and Ballybay areas of Co Monaghan with many areas of farmland under
water .
In N Ireland around Ballymena many trees were down as commutters described driving
along the motorway littered with bits of tree and branches everywhere In the north Malin Head reported a gust of 83mph.
In the SW of England rail services were hit with damage to train tracks at Dawlish in Devon. In
Cornwall, trees fell and some boats on the Fal estuary broke away from moorings in southerly winds. More than 1,000 homes
were affected in Truro after problems were caused by electricity circuit malfunctions.
Nevertheless, many areas further east were very sunny and warm
in the strong S-SW'ly flow and Sutton Bonington (Notts) recorded a maximum temperature of 29.0C, the highest temperature
ever recorded on the 22nd Sept.
The following frontal systems biggest story was the rain, the area of
cloud having its origins at low latitudes and carrying lots of moisture. Forecasts were for up to 20mm across much
of eastern England and Wales enhanced by topography over SW England and Wales. In the event heavy showers and thunderstorms occurred in the east in particular as the
airmass destabilised with Wainfleet (Lincolnshire) recording 42.2 mm, including a total of 21.8 mm in one hour. The low
lay over E Scotland by midnight 1002mb before it and its fronts moved away into the North Sea .
