Recent heavy rain over north-west Britain
20 November 2009
The last few days has seen heavy rain affecting parts of north-west Britain. This was caused by an Atlantic weather front becoming almost stationary across Northern Ireland, Cumbria and south-west Scotland.
In Cumbria, there has been 372.4 mm of rain at Seathwaite and 361.4 mm of rain at Honister between 0800 on Wednesday 18 November and 0400 on Friday 20 November.
Provisionally, the 24-hour total at Seathwaite (ending 0045 on Friday 20 November) of 314.4 mm is a UK record for a single location in any given 24-hour period. Records go back to 1914.
