Stormy weather 13 and 14 November 2009

17 November 2009

Background

A very unsettled spell of weather affected all parts of the UK between Thursday 12 and Sunday 15 November, culminating in a particularly stormy, wet period on Friday and Saturday. 

On Friday 13, a complex area of low pressure developed to the southwest of Ireland and moved north-east across the Irish Sea and western Scotland on Saturday. This swung bands of heavy rain across the UK giving significant accumulations in many western and southern areas. Some parts of Hampshire and Sussex recorded 30 mm of rain in 3 hours on Friday. The southerly wind strengthened to gale or severe gale force through Friday afternoon and evening, with gusts 65 to 75 m.p.h. in places. A second period of very strong winds and squally showers moved quickly across southern parts of Britain on Saturday with gusts widely reaching 50 to 60 m.p.h. and 80 to 90 m.p.h. in exposed coastal locations. There were also reports of tornadoes in the east of England on Saturday.

Impacts

Dover closed as winds hit 100mph (the Independent)

Mid and West Wales Fire and Rescue Service carried out a number of water rescues in Pembrokeshire and Carmarthenshire:

In Cornwall and Devon many roads were affected by surface water flooding, with problems exacerbated by trees and branches being brought down by the gales. These also brought down some power cables and caused damage to some roofs in Devon and Dorset. Part of the Camel Trail in Cornwall was closed due to fallen trees, and local authorities and the Highways Agency were also very busy keeping roads open. Coastal flooding was also reported in some places, especially Dorset, where the severe gales coincided with a high tide.
