Sheets of precipitation ran off the waterlogged ground and into the becks and rivers, which stampeded downhill causing landslides and destroying bridges and collapsing embankments. . . . few Lakeland valleys escaped. Waterfalls cascaded down crags, sweeping scree on to roads so that rocks litter the tarmac, some big enough to have smashed through drystone walls and leave gouges in the fellsides in their wake.
About 25 cm of rain fell in 24 hours, making it the wettest day ever recorded in Cumbria. This quantity is the equivalent of the rainfall usually experienced in the Southeast of England over 5-6 months. Newcastle University researchers have found that rainstorms in the UK have doubled in intensity over the last 40 years, due in part to increased water evaporation from warmer seas.
