Householders are bracing themselves after heavy rainfall in northern England and Wales caused surging river levels to teeter near bursting point.
Temporary flood defences were put up following prolonged deluges on Saturday that prompted the Environment Agency to issue 28 flood warnings in the worst hit communities.
Forecasters have predicted more rain in northern regions, adding to fears that some rivers could breach their banks.
A number of flood warnings are in place in Cumbria, with low-lying areas along the River Eden including Appleby and Carlisle at risk. Parts of Yorkshire and Northumberland have also been issued with warnings, including Masham, Ilkley, Wetherby and Falstone.
According to the Environment Agency, a flood warning means flooding is expected and that immediate reaction is required.
The rain is set to continue, with showers expected to fall on already sodden ground in northern England and Wales.
Lindsay Dovey, a forecaster with MeteoGroup, the weather division of the Press Association, said: “(On Sunday) a band of rain will move across Wales and north west England which will move south east throughout the day.
“There will be heavy bursts in it which will add to the high levels which have already fallen. Scotland will also experience heavy rainfall of up to 10mm per hour this morning, which will break up throughout the day.”
In Shap, Cumbria, 110mm of rain was recorded on Saturday along with wind gusts of 69mph.
People in the worst-hit regions have been urged to check the Environment Agency website for the latest flood situations and sign-up for free flood warnings.
