First responders are still working to manage widespread inundation triggered by the passing storm.
A major incident was declared in Monmouth, south-east Wales, where residents were rescued or evacuated from waterlogged properties after torrential rain on the weekend.
On Sunday morning, multiple major flood warnings, indicating a danger to life, remained active, alongside 41 flood warnings across England. River levels on the Monnow surpassed all-time highs, topping levels seen during past storms.
Homes, businesses, transportation systems, and energy infrastructure all experienced damage from significant flooding in parts of Wales, officials confirmed.
Data indicated that around 20 homes and businesses in England were flooded due to the severe conditions, such as properties in the Cumbria region.
As the storm system moves away, a cold snap is expected to sweep across the United Kingdom, bringing sub-zero conditions and potential wintry precipitation.
Over the weekend, the UK experienced its coldest evening since late March, with mercury readings plunging to -7C in Tulloch Bridge, Scotland.
A temperature drop of around 5C will shift unseasonably warm November temperatures to lower figures nationwide, with peak temperatures on Sunday at around 11 degrees in south-east England before further cooling at the start of the week.
"As Storm Claudia retreats, high pressure to the north-west will bring a cold northerly flow across the country," a weather expert stated. "This results in significantly chillier weather than lately, and, while generally drier, there is also a risk of snow and ice. Frost across many areas are expected, with temperatures dipping as low as minus seven in some places next week, and daytime highs staying in single figures."
He added, "Couple this with a chilly northern breeze, and there will be a marked chill factor. This represents a significant shift after a prolonged spell of above-average temperatures."
Health authorities have activated a warning for low temperatures for parts of the Midlands and northern England from the start of the week, while environmental agencies have warned that flood risks may persist throughout the coming days.
The low-temperature warning is effective from 8am Monday until Friday morning, covering the East Midlands, West Midlands, northeast, northwest, and Yorkshire region.
