THE Met Office has issued a second yellow weather warning for Gwent for this week, likely to cause an ice cold St David’s Day.

Snowfall is forecast across the region, and the first warning, which comes into effect at 0.05am on Tuesday, February 27, is in place for Blaenau Gwent, Caerphilly, Monmouthshire, Newport and Torfaen.

This has now been extended to cover almost the whole of Wales – only Anglesey not included – and will remain in place until 11.55pm on Tuesday.

Now, the Met Office has issued another yellow warning, for wind and snow, from 12pm to 11.55pm on Thursday, March 1.

The second warning covers Blaenau Gwent, Caerphilly, Monmouthshire, Newport and Torfaen also.

Heavy snow could fall, accompanied by strong winds, and this may cause delays and cancellations for commuters and air passengers.

Deep snow may result in stranded vehicles and the Met Office is warning that supplies could be interrupted because of the weather.

The chief forecaster said: “A weather system is expected to move slowly north through Thursday into Friday and has potential to produce widespread snow, accompanied by strong to gale force winds.

“As less cold air follows from the south, there is a small chance of snow turning to freezing rain bringing an additional ice risk.

“There is still uncertainty in how this system will develop, but there is a small chance of the combined effects of snow, strong winds and ice leading to severe impacts.”

On Tuesday, the Met Office is warning that snow could cause delays and cancellations for air and rail passengers, with concerns for motorists also highlighted.

A number of rural communities could be cut off as a result of heavy flurries, and there is a risk of power cuts and other services, such as mobile phones, may be affected.

Regarding the first warning, the chief forecaster said: “Further snow showers are expected through Tuesday, with the potential for a more organised area of snow to push southwest across parts of England and Wales.

“Separate amber warnings are being issued to cover those areas which currently look most likely to see impacts.

“There is the potential for five to 10cm of snow in places though nearby locations may see only small accumulations of zero to 2cm.

“The warning area has been adjusted to take into account latest indications.

“Strong winds may lead to drifting of lying snow – and severe wind chill – especially over hills, with lightning perhaps an additional hazard near North Sea coasts.”
