There is a threat of "significant flooding" in northern England, as heavy rain continues to fall on already flooded and saturated ground.
The Environment Agency (EA) warned of worsening conditions across the Pennines after heavy rainfall over the weekend after Storm Dennis.
Record river levels have been broken on the River Ribble, the River Lune is also showing high levels.
Director of incident management Caroline Douglass has warned people to be "aware of their flood risk".
She said: "This is the third weekend we have seen exceptional river levels and stormy weather, and with the effects of climate change, we need to prepare for more frequent periods of extreme weather like this."
The EA predictions were echoed by the Met Office, who have forecast another deluge across northern regions and parts of England in the coming days.
Yellow weather warnings for rain and wind remain in place throughout the week in the north of the UK.
Met Office forecaster Grahame Madge said: "There is still heavy rain in the forecast, and some of this will be falling on areas already affected by flooding."
Overnight, a new weather front will bring rain to parts of Northern Ireland and Scotland, and will move south towards the Lake District and the North Pennines by morning.
Levens Hall, in Cumbria, was subjected to 55.2mm of rain, and Morecambe, Lancashire, got 51.6mm in the last 24 hours.
