UK weather forecast: Three dead as heavy rain and high winds brought by Storm Callum continue to batter Britain

Forecasters have warned of potential flood misery for much of Britain’s west coast, as the torrential rain brought by Storm Callum is set to batter the country again on Sunday.

Yellow warnings for floods remain in place across northwest England, the south of Scotland and most of Wales, which saw some of its worst flooding in 30 years on Saturday.

Both the River Towy and the River Usk in south Wales burst their banks, flooding homes, cutting power and causing travel chaos across the region. A man died in a landslide on the A484 near the village of Cwmduad in Carmarthenshire, Dyfed-Powys Police said.

Another died after being swept away by rough seas in Brighton, East Sussex, at 1.30am on Saturday. The man was found in water near Brighton Palace Pier and checked by paramedics who pronounced him dead, the Maritime and Coastguard Agency said.

A third man died after being rescued from a marina in south Wales.

The 32-year-old was pulled from Penarth marina in the Vale of Glamorgan by the coastguard and fire service shortly after 10pm on Friday.

He died in hospital a short time later.

A 35-year-old woman, who was also rescued from the marina, was released from hospital with no injuries.

The torrid weather is expected to continue into Sunday, as heavy rain moves northwards and eastwards across the country.

Forecasters said the wet conditions could finally ease in Wales, which bore the brunt of the storm on Saturday, before the end of the weekend.

The rainfall which has plagued western Britain will make its way east as the day progresses, weakening as it does so, meaning by the afternoon there will be a “reversal in fortunes”, the Met Office said.

“The areas that have seen the bulk of the sunshine over the last couple of days will then be under the cloud, with patchy, light rain and drizzle at times,” said meteorologist Simon Partridge.

“Those areas further west which have seen huge amounts of rain will finally turn drier, brighter, with some decent sunny spells developing by the end of the day on Sunday,” he added.

As Sunday dissolves into Monday, cloud and patchy rain will remain in the south east, with generally clear, dry conditions further north and west.

“There’s a cool clear start for many parts of the UK on Monday, and actually for much of the UK it’s a dry fine and sunny day to boot,” Mr Partridge said.

Clouds and patchy rain will remain over the south-east corner of the UK until the early hours of Tuesday with a drier, cooler outlook expected for the week, he added.

Downpours brought by the storm caused widespread disruption across the UK on Saturday.

Residents in the village of Canal Side in Aberdulais, south Wales were placed on evacuation alert because of high river levels.

Around 100 sheep were washed away in flood water in Carmarthenshire, and a horse had to be rescued from the flooded River Usk in Monmouthsire.

The town of Crickhowell was hit by some of the worst flooding as water from the River Usk flowed into roads. Residents described the town as an “island” as main roads out of the area were briefly blocked.

Teams from Natural Resources Wales used sandbags in an attempt to divert the floodwaters.

Elsewhere, flooding and falling trees reduced Virgin services between London Euston, Birmingham New Street, and Edinburgh and Glasgow, and delays in Devon and Cornwall.

A landslip stopped all Virgin trains running between Preston and Carlisle with the company posting images of the half-submerged tracks.

Speed restrictions were imposed on dozens of other rail routes, causing severe travel delays.

A key road in Scotland, the A83 at the Rest and Be Thankful in Argyll and Bute, was also closed following tonnes of debris falling on to it after multiple landslips.
