Parts of northern England have endured a month’s worth of rain in 24 hours, forcing many to leave their homes.
More than 100 flood warnings are in place across England. The Environment Agency (EA) has urged people to take them seriously.
Five severe warnings – meaning a danger to life – are in place along the River Don in Doncaster.
Here are pictures of some of the affected areas.
