History

Historical Context

During June-July 2007 the United Kingdom suffered its wettest May-July period on record, with the Environment Agency reporting about 44,600 homes flooded and damage near £3 billion; Prime Minister Gordon Brown and Environment Secretary Hilary Benn pledged £800 million for flood defence. The crisis prompted the Met Office to begin issuing severe-weather warnings and a 24-hour forecasting service, foundations of today’s colour-coded alerts.
