South Wales could see another round of sleet and snow over the coming days, with a flurry predicted in Swansea tomorrow and potentially heavy snowfall in Cardiff tonight.

Yellow weather warnings of snow and ice are in place across many parts of South Wales today, with the Met Office predicting icy stretches on untreated surfaces.

The Swansea skies are set to be overcast today and tonight, and sleet is forecast from around 6am to 9am tomorrow.

Swansea could see light snow tomorrow from around 6pm, and it could continue to fall until around midnight.

There is a 40 per cent chance of precipitation - that is, rain, sleet or snow - tomorrow night, the Met Office says.

Temperatures will linger around the 2C mark both tonight and tomorrow night, but the Met Office says it could feel much colder - as low as -3C.

Meanwhile gusty winds may pick up in Carmarthen today, reaching 23mph at various intervals. The chance of precipitation stands at 20 per cent today, but it could feel as cold as -3C.

The skies will be overcast tomorrow, and light snow may fall from around 9pm until midnight.

The sun is set to shine in Carmarthen on Thursday afternoon, but it could feel as cold as -2C.

Yellow weather warnings of ice remain in place until Wednesday afternoon.

Light snow is forecast in Neath tomorrow night, with a 40 per cent chance of precipitation. A flurry is predicted from around 6pm until the early hours of Thursday.

As in Carmarthen, a sunny but cold afternoon looks set to follow.

Yellow weather warnings of snow and ice are in place in Neath today, but the Met Office says there is only a 20 per cent chance of precipitation.

Snow seems most likely to fall in Cardiff. There, the white stuff is forecast from around 3pm today, developing into heavy snow overnight. There is a 60-80 per cent chance of precipitation tonight.

The snow will most likely subside by around midnight, and fall gently until lunchtime on Wednesday. The rest of the afternoon will be overcast, and temperatures could feel as low as -3C.

Cardiff could see another light flurry of snow in the early hours of Thursday. The rest of the day looks set to be cold and cloudy.

UPDATE 11.30AM

The Met Office has upgraded the weather warning for snow in South Wales to amber.

The warning, which urges the public to "be prepared", has been issued from 3pm today until midday tomorrow.

Some 10 cm of snow could fall amber warning areas, the Met Office says. This could be locally heavy and fall in a short period of time, perhaps just a few hours.

The yellow warning of ice in South Wales remains in place - in Swansea, Neath, Carmarthen and Swansea until midnight.

UPDATE 1PM

The sleet and snow set to hit South Wales over the coming days has been downgraded to cloudy and overcast skies, it appears.

Sleet was originally forecast in Swansea from around 6am to 9am tomorrow, and light snow from around 6pm.

However, the latest Met Office forecast this afternoon predicts only cloudy and overcast skies.

An amber snow warning is in place from 3pm today until midday tomorrow, however, and a yellow ice warning throughout today until 12pm tomorrow.

Similarly, light snow was predicted to fall tomorrow from around 9pm until midnight in Carmarthen. However, the latest Met Office forecast predicts only cloudy and overcast skies.

And instead of light snow in Neath tomorrow night it will simply be overcast, the latest forecast says.

The amber and yellow weather warnings remain in place, however.

UPDATE 2.20PM

More snow may fall in Cardiff on Wednesday than was previously thought.

According to the latest Met Office forecast, light snow will fall from around 6pm tonight, developing into heavy snow overnight.

The snow should subside by around 3am, and fall gently over the coming hours. But while the afternoon was previously forecast to be cold and cloudy, the Met Office now predicts snow.

Heavy snow is forecast from midday tomorrow, easing off into a light flurry at 3pm. There may then be a snow-free interval, but the white stuff is set to fall again lightly for several hours from 9pm.

UPDATE 3.15PM

Darron Burness, the AA’s Head of Special Operations, said the South West was this morning, "hit by a dangerous cocktail of rain, sleet and hail".

He said: "The rain washed away some of the salt on the roads, so the hail then froze, creating treacherous sheet ice and causing a spate of accidents."

Urging caution on the roads, Mr Burness said: "On snow and ice the key is to drive smoothly, avoiding hard acceleration, braking and steering movements.

"Try to stay in the highest gear possible to avoid wheel spin. If your car skids, only hit the brakes if you have anti-lock brakes.

"If you don’t have anti-lock brakes, try to regain control by lifting off the pedals and depressing the clutch to help the wheels regain traction.

"It’s easier said than done, so keep your speed down and try to keep plenty of space around you at all times.

“If you’re on a hill, try to avoid having to stop part way up by waiting till it’s clear of other cars or by leaving plenty of room to the car in front.

"Keep a constant speed and choose the most suitable gear well in advance to avoid having to change down on the hill.

"Likewise, if you’re going downhill, reduce your speed before the hill, use a low gear and try to avoid using the brakes.

“Wherever you’re travelling this week, stick to the gritted main roads where possible and keep tuned to local radio for the traffic and weather reports.”

UPDATE 4.10PM

Heavy snow could fall continuously in Cardiff from 6pm today until around 3pm tomorrow, according to the latest Met Office forecast.

In its latest update, the Met Office predicts heavy snow may not subside until tomorrow afternoon. There may be a brief snow-free interval between 3pm and 6pm on Wednesday, but another flurry of the white stuff is forecast at around 6pm.

Temperatures in Cardiff are expected to fall to zero overnight on Tuesday, but the Met Office warns it could feel as cold as -4C.
