Heavy rainfall caused widespread flooding across Cumbria in northern England in 2009, with a conveyor of warm, moist air from the Azores bringing 34 hours of steady rain to the region. The floods were especially severe where rivers converged in towns like Cockermouth, due to the heavy rain overwhelming drainage systems. Thousands of homes and businesses were damaged by the flooding, costing over £3 billion to repair the infrastructure and helping to make 2009 the wettest year on record for the UK.
