Storm Christoph is set to deluge Britain with two months worth of rain in 36 hours as families have been told to start moving furniture upstairs to protect against flooding. Vast swathes of the North and Midlands are being warned of a “danger to life” and whole communities could be cut off, the Met Office has said. Amber warnings have been put in place across Manchester, Leeds, Sheffield, Nottingham, Leicester and Peterborough for Tuesday, affecting millions of people, as the first named storm of the year is expected to last for three days. Already, there are 56 flood alerts and 11 flood warnings in place, with the River Ouse and River Witham both in danger of bursting their banks. In Doncaster, the local council has been delivering sandbags to people in properties that are most at risk.
