Fresh flood warnings have been issued as further heavy rain and strong winds due to batter Britain this week bring a new risk of danger and disruption.
Devon, Somerset and south east Wales are likely to be the worst hit by the new downpours, the Environment Agency said, with strong winds meaning coastal defences could be overrun.
The UK has already been battered by winds of up to 60mph on Monday and they could be whipped up to 85mph by Tuesday night, according to Meteogroup, the weather division of the Press Association.
Mobile flood barriers are being erected in Bewdley in Worcestershire and Shrewsbury in Shropshire in preparation for large rivers, including the Severn and the Wye, rising to flood levels during the week.
"Communities in the south west of England and south-east Wales are being urged to prepare for more flooding this week as further rain fall is likely to cause flooding and significant disruption," an Agency spokeswoman said.
"Devon, Somerset and south-east Wales are most likely to be affected, and strong winds could lead to some disruption along the coast as waves and spray come over the top of defences."
A deep Atlantic storm is one of a series of weather systems heading to the UK, Meteogroup said, bringing fresh rain falling on ground saturated by recent downpours and the thaw from last week's snow.
A canoeist died and more than 40 properties across England and Wales flooded over the weekend.
The Environment Agency had 45 flood warnings and 193 less serious flood alerts in place on Monday afternoon.
It warned that this number would increase as more rain came in.
