Storm Dennis hit Britain over the weekend, causing transport chaos and hundreds of floods.
This latest storm follows Storm Ciara , which struck the country about a week ago.
Storm Dennis caused major incidents in South Wales and parts of England.
Local emergency services have been dealing with multiple landslides and floods, and had to rescue trapped residents.
On Sunday, a record 600 flood warning and alerts were issued in England.
Among them, four severe flood warnings, meaning a danger to life, were issued in England and two in Wales.
The body of a man was recovered from the River Tawe , but local police said his death was not because of the extreme weather.
People are being evacuated in the affected regions.
"Last night the water board was knocking on our door, saying, move the cars, and we moved the car and after then, just rapidly the water rose, and suddenly it's in the house."
Some have raised disappointment over not being properly protected from the natural disaster.
"I mean anger will probably come later, but disappointment it just how I feel, because as a community we've put our faith in somebody to try and protect us from this happening, and it's failed."
Across the UK, road, rail and air routes were closed.
Some 170 flights were cancelled on Sunday, which affected about 25-thousand passengers.
Railways and roads were also closed.
The storm also affected north-west France.
Nearly 14-thousand homes were left without power in Bretagne because of strong winds.
