Torrential rainfalls and gales swept large parts of northern Britain Monday, with the counties of Yorkshire and Lincolnshire worst affected. Police said three people were rescued by helicopter from the canteen of a factory building in Sheffield late Monday. Reports said cars were floating through the flooded streets of Sheffield and the picture was similar in the nearby city of Leeds, in Yorkshire, where a central underground car park was completely flooded and people who had abandoned their cars were housed in emergency accommodation. There has been major disruption to road and rail traffic as railway tracks were flooded and motorways water-logged. Hundreds of homes in the affected areas, which reached down to the county of Gloucestershire in the south-west and into Wales, were evacuated and schools closed. The authorities in South Yorkshire declared the situation a "major incident" while in Lincoln, World War II sirens were sounded to warn people of the danger.
