Downpours and high winds are likely to continue after Storm Ingrid wreaked havoc in the south-west and washed away part of a historic pier in Devon, the Met Office said on Saturday.

It has been a wet weekend for many, with yellow weather warnings for heavy rain in place across parts of Northern Ireland, Scotland and south-west England and Wales.

A yellow warning was in place for an area covering Somerset, Devon and Cornwall and much of south Wales until 10pm on Saturday, while separate warnings in Northern Ireland and Scotland will run until 9am on Sunday.

Approximately 20-40mm of rainfall is expected across most of the south-west – while some exposed locations could see up to 50mm, the forecaster said, with a risk of flooding to areas battered by rain in recent days.

Storm Ingrid, as named by the Portuguese national weather service IPMA, caused chaos with powerful waves in parts of the south-west on Saturday.

In the Devon coastal town of Teignmouth, part of its Victorian pier collapsed with the force of the waves.

The town’s mayor, Cate Williams, said that Teignmouth had seen unusually high winds and strong waves which damaged benches, flower beds and paving stones near the seafront, as well as the historic pier.

“It’s really sad … it’s such a focal point of our town,” she added.

The Environment Agency has issued 13 flood warnings which remained in place across south-west England at 5pm on Saturday, meaning flooding is expected, while 135 flood alerts indicated flooding is possible in many parts of the country.

Major disruption to railway services in south-west England was expected to last all day on Saturday, National Rail said, as passengers faced cancellations and delays.
