Emergency crews are continuing their efforts to address extensive flooding triggered by the recent storm.
A major incident was announced in the town of Monmouth, southeastern Wales, where individuals were safely removed from flooded properties after heavy downpours on the weekend.
On Sunday, multiple major flood warnings, indicating a danger to life, were still in effect, alongside 41 flood warnings across England. Water heights on the Monnow exceeded all-time highs, surpassing levels seen during previous severe weather events.
Homes, businesses, transportation systems, and power grids all suffered from major water inundation in parts of Wales, officials confirmed.
Data indicated that around 20 homes and businesses in England were flooded due to the storm, including some in the Cumbria region.
As Storm Claudia moves away, a cold snap is expected to move across the UK, bringing sub-zero conditions and potential snow and ice.
Saturday night, the country experienced its coldest evening since late March, with temperatures plunging to minus seven degrees Celsius in a Scottish location.
A decline of approximately five degrees will shift above-average autumn readings to lower figures across most of the UK, with peak temperatures on Sunday reaching about 11C in south-east England before further cooling at the week's beginning.
"As Storm Claudia moves south, atmospheric pressure to the north-west will bring a chilly Arctic air across the UK," a meteorologist stated. "This will bring significantly chillier weather than recently, and, while generally drier, there is also a risk of snow and ice. Frost across many areas are expected, with readings dipping as low as -7C in some places next week, and daytime highs staying in single figures."
He added, "Combine this with a chilly northern breeze, and there will be a significant wind chill. This represents a significant shift after a extended period of unseasonable warmth."
Health authorities have issued a warning for low temperatures for several English regions from the start of the week, while environmental agencies have cautioned that flooding may persist throughout the coming days.
The cold weather alert is effective from Monday morning until 8am next Friday, covering the eastern Midlands, West Midlands, North East, northwest, and Yorkshire and The Humber.
