Storm Callum is expected to cause further disruption on Saturday as the UK continues to be battered by heavy downpours.

In Wales further flood warnings have been issued as the heavy rain continues.

Natural Resources Wales said that over the last few days, rain gauges have recorded totals of more than 160mm (five inches) of rain in the Brecon Beacons.

The rain is forecast to continue, and with rivers already high it is possible that south Wales may see further flooding throughout the day.

There are currently 28 flood warnings in place across south Wales with a further 39 flood alerts – and this could rise.

A yellow warning also covers parts of Scotland and the north west and south east of England.

Rail services were plagued by delays, with severe weather affecting services between Preston and Scotland, across Wales, and in South West England.

Strong winds have seen speed restrictions imposed on many routes – with reduced Virgin services between London Euston, Birmingham New Street, and Edinburgh and Glasgow, Network Rail said.

Flooding and falling trees have seen major disruption across most rail services in Wales, while trains in Devon and Cornwall are also likely to be delayed.

Thousands of households were left without power and dozens of flights grounded on Friday as torrential rain and winds of more than 70mph buffeted the Republic of Ireland, Northern Ireland and the west coast of Britain.

One part of south Wales, the Brecon Beacons village of Libanus, recorded 182mm of rain in just 48 hours – way above the monthly total for the region of 169mm.

Forecasters are warning of more of the same over the weekend, although some parts of England will escape the worst.

But there was a silver lining – well, a pink yellow and blue one.

Met Office meteorologist Helen Roberts said: “There will be more wet and windy weather for similar parts of the country – predominantly western areas – which could cause more flooding.

“The east and south east of England will see the best of the drier and brighter weather, where it will be even warmer than yesterday and could reach 25C – way above average for the time of the year.”

Overnight, several police forces reported accidents on the roads due to surface water, while Network Rail said it was expecting disruption to train services throughout Saturday and advised passengers to plan ahead.
