Strong winds 10-12 March 2008

Strong winds over England and Wales caused some disruption to transport and power supplies over this period...

10 March 2008

On 10 March 2008, a deep area of low pressure moved east across southern Ireland, central Wales and Lincolnshire, with the southern half of England and Wales worst affected by strong winds. The lowest pressure on the 6-hourly analysis charts was 946 hPa to the west of Ireland at 00 UTC on 10 March 2008 (see chart below). There was disruption to transport and power supplies, with restrictions imposed on several major bridges, including the old Severn and the Tamar bridges, with the QE2 and Sheppey crossings closed. Cross-Channel ferry crossings were cancelled and 30,000 homes suffered a loss of power. The combination of strong winds, low pressure and a high tide, resulted in coastal flooding at several places on the south coast.

In comparison with previous stormy weather, it was actually the low pressure values which had the greatest significance.

Lowest pressure over Wales was 954.4 hPa at Aberdaron (Gwynedd) and Aberporth (Ceredigion) at 1100 UTC and Milford Haven (Pembrokeshire) at 10:00 UTC . This was the lowest pressure over Wales since 17th December 1989, when 947.4 hPa was recorded at Valley (Anglesey).

Lowest pressure over England was 957.1 hPa at Shobdon Airfield (Herefordshire) at 1300 UTC. This was the lowest pressure over England since 30 October 2000, when 951.2 hPa was recorded at Fylingdales (North Yorkshire).
