First responders are still working to address extensive inundation caused by the passing storm.
A significant emergency was declared in the town of Monmouth, south-east Wales, where residents were rescued or evacuated from waterlogged homes after torrential rain on the weekend.
On Sunday morning, four severe alerts, indicating a danger to life, remained active, alongside 41 flood warnings across England. Water heights on the Monnow River exceeded all-time highs, surpassing levels seen during past storms.
Homes, commercial properties, transportation systems, and power grids all experienced damage from significant flooding in Welsh regions, authorities confirmed.
Data indicated that around 20 homes and businesses in England experienced flooding due to the severe conditions, such as properties in Cumbria.
As Storm Claudia moves away, a sharp temperature drop is expected to move across the UK, bringing sub-zero conditions and possible wintry precipitation.
Over the weekend, the country experienced its chilliest evening since spring, with temperatures plunging to minus seven degrees Celsius in a Scottish location.
A decline of around 5C will shift unseasonably warm autumn readings to lower figures nationwide, with peak temperatures on Sunday reaching around 11 degrees in the southeastern region before further cooling at the week's beginning.
"While Storm Claudia retreats, high pressure to the north-west will bring a chilly Arctic air across the UK," a meteorologist stated. "This results in much colder weather than lately, and, while generally drier, there is also a potential of wintry hazards. Frost across many areas are anticipated, with readings falling as low as minus seven in certain locations next week, and daily maximums staying in the single digits."
He added, "Couple this with a chilly northern breeze, and there will be a marked wind chill. This marks a notable change after a extended period of unseasonable warmth."
Public health agencies have activated a cold weather alert for several English regions from the start of the week, while flood management bodies have warned that flood risks may continue throughout the coming days.
The cold weather alert is in place from Monday morning until 8am next Friday, covering the eastern Midlands, West Midlands, northeast, northwest, and Yorkshire and The Humber.
