The Environment Agency has issued 11 flood warnings and 114 flood alerts across Britain.
According to the Express, more than an inch of rain fell in Southern England yesterday and a further inch is expected today, with coastal areas are particularly at risk.
An Environment Agency spokesperson told the newspaper: 'Morning tides over the next three days are critical periods. Large waves and high tides bring the risk of coastal flooding in the South-west and South, while heavy rain brings a risk of river flooding.
'People should check for flood warnings at places which are at risk and avoid walking along the coast.'
Meanwhile, Rachel Vince, a MeteoGroup meteorologist, told the Daily Mail: 'Through the weekend the UK is looking at a relatively mild picture compared to recent days, with temperatures in the double figures.
'The wet weather looks like being largely confined to the South and West, where we'll see a mixture of sunshine and showers.
'Unfortunately there is no significant dry weather down in the South West, but the precipitation will become more showery rather than the persistent rain they had through the night.'
Leon Brown of The Weather Channel told AOL Travel that 'flooding will again be a risk on Saturday morning with some very high rivers.'
He said the weather in the south-west is expected to be 'fine and bright with some sunshine for central and eastern England on both Saturday and Sunday.'
But in the west 'expect rain showers, some heavy over west Wales.'
Scattered showers are predicted for Monday before another 'very wet spell late Wednesday to Thursday next week.'
Mr Brown added that the higher Pennines and high ground in Scotland will see snow, though the south will be 'mild'.
