Emergency crews are continuing their efforts to address widespread flooding triggered by the passing severe weather.
A significant emergency was announced in Monmouth, south-east Wales, where residents were safely removed from flooded properties after torrential rain on the weekend.
On Sunday morning, multiple major flood warnings, indicating a danger to life, remained active, alongside dozens of alerts in England. Water heights on the Monnow River surpassed previous records, topping levels recorded during previous severe weather events.
Homes, commercial properties, transport networks, and energy infrastructure all suffered from significant flooding in Welsh regions, authorities confirmed.
Reports indicated that around 20 properties in England were flooded due to the severe conditions, including some in Cumbria.
As the storm system moves away, a cold snap is forecast to sweep across the United Kingdom, bringing sub-zero conditions and possible wintry precipitation.
Saturday night, the country experienced its chilliest evening since spring, with mercury readings dropping to minus seven degrees Celsius in Tulloch Bridge, Scotland.
A temperature drop of around 5C will shift above-average November readings to lower figures across most of the UK, with peak temperatures on Sunday at around 11 degrees in south-east England before becoming colder at the start of the week.
"While the storm retreats, atmospheric pressure to the north-west will drive a chilly Arctic air across the UK," a meteorologist stated. "This results in significantly chillier weather than recently, 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 the single digits."
He added, "Combine this with a brisk northerly wind, and there will be a significant wind chill. This marks a notable change after a extended period of unseasonable warmth."
Public health agencies have issued a cold weather alert for several English regions from Monday, while flood management bodies have cautioned that flooding may continue throughout the coming days.
The low-temperature warning is effective from 8am Monday until 8am next Friday, covering the eastern Midlands, West Midlands, northeast, northwest, and Yorkshire and The Humber.
