The Lake District climate is generally mild due to the influence of the sea. Occasionally however, the Lake District sees weather conditions which are out of the ordinary.
“A once in a thousand year event” they called it. 19 November 2009 saw 314.4mm of rain fall on Seathwaite in Borrowdale in one 24 hour period.
The River Derwent and the River Cocker which drain the Borrowdale and Buttermere valleys simply could not contain that amount of water. By early afternoon on 19 Nov 2009 the main street of Cockermouth was a raging torrent. People had to be rescued by boat from the upper floors or even the roofs of their houses.
The River Greta in Keswick also burst its banks flooding homes and businesses. Across Cumbria six bridges collapsed under the force of the water and all 1800 bridges in the county needed checking. Around 1300 homes and businesses were destroyed by the floods in Cockermouth, Keswick, Ulverston, Workington, Kendal and other smaller communities.
The Lake District National Park had properties flooded at Bowness Bay Tourist Information Centre and Coniston Boating Centre. However Cumbria Tourism was quick to reassure tourists that many areas of Cumbria were unaffected.
According to the Met Office this unprecedented level of rainfall was due to an Atlantic weather front becoming almost stationary over Northern Ireland, Cumbria and south-west Scotland.
This front and the south-westerly winds associated with it drew very warm, moist air up from the Azores region. The rain was intensified by the effect of the mountains causing record breaking rainfall totals. The ground was already saturated from weeks of heavy rainfall and disaster was inevitable.
We do not know the answer to this. Climate experts tell us that as the planet warms, extreme weather events will be more common. We have to be prepared.
