Met Office weather warning of ice for commuters in Wales
Motorists are being urged to take care on the morning commute with ice predicted for the whole of Wales.
Gritters were out on roads on Wednesday evening after a Met Office yellow "be aware" warning came into effect at 22:00 GMT.
It is expected to continue until 11:00 on Thursday.
Forecasters warned of possible injuries due to slippery paths and roads, and of ice on some untreated roads, pavements and cycle paths.
Alongside the ice, wintry showers are expected over hills and mountains, but may also occur over lower ground too.
BBC weather presenter Derek Brockway said the cold weather was not the start of another "Beast from the East" in Wales.
"There's nothing unusual or extreme coming, it's just a cold snap," he said.
"It's the routine cold weather you would expect in January. We are going into a colder period, but there's no sign of anything unusual or a big freeze like we've seen in Europe.

"There's no sign of widespread disruption from snow. Just be aware it could be a bit icy."
Carmarthenshire council were among local authorities taking action overnight and urging motorists to take extra care on Thursday morning.
