Emergency crews are continuing their efforts to manage widespread inundation triggered by the passing storm.
A major incident was announced in Monmouth, south-east Wales, where residents were safely removed from waterlogged homes after heavy downpours on the weekend.
On Sunday morning, multiple major alerts, warning of life-threatening conditions, were still in effect, alongside dozens of alerts in England. Water heights on the Monnow River surpassed all-time highs, topping levels seen during previous severe weather events.
Homes, businesses, transportation systems, and energy infrastructure all experienced damage from significant flooding in Welsh regions, officials confirmed.
Data indicated that approximately twenty properties in England were flooded due to the storm, such as properties in Cumbria.
As the storm system moves away, a cold snap is expected to move across the United Kingdom, bringing freezing temperatures and potential snow and ice.
Saturday night, the country experienced its coldest evening since late March, with mercury readings dropping to minus seven degrees Celsius in Tulloch Bridge, Scotland.
A decline of approximately five degrees will shift above-average autumn temperatures to lower figures across most of the UK, with peak temperatures on Sunday at around 11 degrees in south-east England before further cooling at the start of the week.
"While Storm Claudia retreats, high pressure to the northwest will bring a cold northerly flow across the UK," a meteorologist stated. "This results in significantly chillier 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 -7C in certain locations next week, and daily maximums staying in single figures."
He added, "Couple this with a chilly northern breeze, and there will be a significant wind chill. This represents a significant shift after a prolonged spell of unseasonable warmth."
Health authorities have activated a cold weather alert for several English regions from Monday, while environmental agencies have warned that flood risks may persist throughout the weekend.
The cold weather alert is effective from 8am Monday until Friday morning, including the eastern Midlands, western Midlands, northeast, North West, and Yorkshire region.
