Motorists are warned of fog and icy roads A new warning has been given to drivers in parts of Wales as freezing weather continues to affect travel and sport.
As the sales began, there was heavy fog on the second Severn Crossing, and Monday’s 1000 GMT Stena Line Holyhead to Dun Laoghaire ferry was cancelled.
The warning came as 12,000 tonnes of grit from Sweden are expected in the next few days to replenish low stocks.
Frozen pipes at the Liberty Stadium has seen the Ospreys’ sell-out Boxing Day derby against the Scarlets called off.
A crowd of more than 20,000 was expected for this Magners League fixture.
A rescheduled date for the match has yet to be fixed.
A frozen pitch has also forced Monday’s rugby derby between Newport Gwent Dragons and Cardiff Blues to be postponed.
The A470 southbound between Abercynon and Pontypridd was partially blocked due to a broken down car, and motorists were warned of icy roads in the Swansea area in particular.
Sunday night: Strong southerly winds developing and becoming generally cloudy. Outbreaks of sleet and snow spreading across the region, leading to some icy stretches. Somewhat less cold than recently. Minimum temperature -1 C (30F).
Monday: Outbreaks of rain and hill snow continuing, mainly in the west. These becoming more persistent and spreading east later. Some thaw of lying snow likely. Southerly winds remaining brisk. Maximum temperature 4C (25F).

When the new grit arrives, it will be distributed to local authorities.
It was ordered by the Welsh Local Government Association, which earlier this week warned of dwindling stocks.
Meanwhile, rail users were reminded that no Valley Lines services are expected to run on Monday due to a strike by Arriva Trains Wales drivers.
The strike was announced after drivers voted for industrial action in a row over pay and conditions.
Arriva Train Wales has apologised for the inconvenience to passengers and said they planned to run a full service on all other routes on the network on Monday.
Forecasters said the weather will remain dry across Wales for the rest of Sunday, and while still cold, less so than recently.
The Met Office warned that any freezing fog would be slow to clear with outbreaks of sleet and snow across Wales leading to some icy stretches.
On Monday, outbreaks of rain and hill snow are forecast, mainly in the west but spreading east later.
The cancellation of Monday’s Newport Gwent Dragons game against Cardiff Blues was described as bitterly disappointing by Mark Jones, stadium manager at Rodney Parade.
“The staff have worked really hard this week to try and ensure that tomorrow’s game will go ahead but we have been beaten by extraordinary weather conditions,” he said.
He added his thanks to supporters who offered to help clear the pitch of snow.
The match will be played at a later date to be scheduled by Celtic Rugby in conjunction with both teams.
