UK weather: Freezing temperatures across country as floods remains

Wintry weather is tightening its grip in many parts of the UK, with sub-zero temperatures expected to plunge even lower overnight.

Forecasters predict the coldest nights of the year over the next two days, and temperatures are expected to fall as low as -20C in some places that endured heavy snowfall at the weekend.

Fresh warnings for snow and ice are in force for parts of the country into Thursday, although their coverage is not as wide as in recent days.

The cold weather comes after earlier flooding caused havoc in central England but, with no further rainfall expected in flood-hit areas in the coming days, flood waters are likely to begin subsiding.

An amber cold health alert – the second-highest level – covering all regions of England is in place until midday on Sunday.

The alert, issued by the UK Health Security Agency (UKHSA), warns the freezing conditions are likely to result in a rise in deaths, particularly among older and vulnerable people, and an increase in demand for health services.

They are different to weather warnings and provide early warning to healthcare providers, and suggest actions such as actively monitoring individuals at a high risk.

Dr Agostinho Sousa, from the UKHSA, said it was “vital that we continue to check in on friends, family and neighbours that are most vulnerable”.

“These people could be more at risk of heart attacks, stroke and chest infections as a result of cold temperatures,” he said.

There are more than 80 flood warnings, meaning flood is expected, and more than 150 flood alerts, meaning is flooding is possible, in place across England on Wednesday afternoon.

One flood warning and four flood alerts are in force in Wales.

Temperatures on Tuesday night widely fell below freezing, with most of the UK waking up on Wednesday to a frost.

The lowest temperature overnight was in Scotland with -7C at Tulloch Bridge. But with -6.9C in Katesbridge, it was Northern Ireland’s coldest night of the winter so far.

Across England, the temperature fell to -8.4C in Shap, Cumbria, but even in southern England it was -6.1C at Benson, Oxfordshire.

In Wales, the lowest temperature was -3.8C in Bala, Gwynedd.

Looking ahead, the flooding and warnings are expected to reduce with no significant rain predicted in the areas experiencing flooding.

The focus will switch to how far temperatures are likely to fall, particularly during the night.

Isolated yellow snow and ice warnings spanning Wednesday and Thursday are in place across the UK, including parts of Northern Ireland and the Scottish Highlands.

Warnings have also been issued for Wales and the south west tip of England from 03:00 GMT until 12:00 GMT on Thursday.

Rain will spread across the far south of England but there will be some snow over Exmoor and Dartmoor, perhaps as much as 10cm (4in) on Wednesday.

Snow may also fall over mainly higher ground later on Wednesday in south-east England.

The wintry conditions have caused significant disruption across the UK since snow swept many parts of the country at the weekend.

Hundreds of schools were closed in England, Scotland and Northern Ireland, including schools in Yorkshire, Merseyside, the Midlands and Aberdeenshire.

Extensive flooding caused some local roads to remain shut on Wednesday in Lincolnshire, while Northern Rail also confirmed no services would stop at Gathurst station near Wigan.

Most flights are running again after they were temporarily halted at airports in Liverpool, Bristol, Aberdeen and Manchester – but operators have warned some delays are still likely.

Bitter cold is expected in many parts of the UK in the coming days, with the likelihood of sharp overnight frosts.

Temperatures are expected to drop well below freezing on Wednesday and Thursday night, with forecasters expecting many parts of the UK to experience a hard frost and lows of between -3C and -10C.

In places that are still experiencing snow cover, it could be as cold as -14C to -16C on Wednesday night, and on Thursday the Pennines and snow fields of Scotland could register temperatures as low as -16C to -20C.

That would actually be far colder than was experienced at the weekend when a low of -13.3 C was recorded at Loch Glascarnoch in the Highlands.

It is also significantly lower than anything seen last winter when a particularly bitter night in Dalwhinnie in the Highlands saw a mark of -14C being recorded.

The last time the UK had any temperature below -20C was in February 2021 when Braemar in Aberdeenshire was measured at -23C.
