Weather warnings to motorists are continuing as more downpours and floods are forecast for the coming week.
MeteoGroup, the weather division of the Press Association, said clear skies on Monday are likely to be the calm before another storm.
Forecaster Matt Dobson said: "We have just seen one of the largest storms of the summer. For most of us the weather will settle down on Monday, with a bit more sunshine, and there will be a bit of respite.
"But Tuesday will see another depression arriving, meaning heavy spells of rain across Northern Ireland, the North East, Wales and southern Scotland."
In Morpeth, Northumberland, the clean-up operation began after Saturday's floods put the high street under 2ft of water, with more than 400 people needing to be evacuated. Many residents were plucked to safety using an RAF helicopter.
A spokesman for the Environment Agency, which has seven severe flood warnings in place for the North East, said: "With river levels being high already, we can expect more floods to hit."
