Snow is forecast to clear away later in south and west Wales after a number of areas were affected on Monday morning.

Motorists had to tackle snowy conditions during the morning, although all main roads remained open.

Up to 2in (5cm) fell in parts of south Wales, with similar amounts in parts of Pembrokeshire and Snowdonia.

Snow, sleet and light rain is expected to move from the area to give drier conditions into the evening, but ice is expected to be a problem later.

A Met Office yellow "be prepared" warning was issued for Monday evening of icy roads, replacing a previous amber warning of snow.

The public were advised to be aware of the need for extra care, especially when travelling.

South Wales was the worst hit at the beginning of what is expected to be the coldest week of the winter so far.

Traffic cameras showed the areas around the A465 Heads of the Valleys road were affected, with snow and sleet falling early on Monday.

Gritting teams were on alert in the Blaenau Gwent council area from Sunday in preparation for snow.

The council had urged drivers to be aware that snow could make journeys difficult on Monday.

Llandrindod High School in Powys was only partially open on Monday due to a "utility failure". It opened to Year 10, Year 11, Year 12, Year 13 pupils only.

BBC Wales' Met Office forecaster Derek Brockway said a band of light rain, sleet and snow will move across south and west Wales during Monday clearing to give drier conditions with the evening and overnight.

Temperatures throughout the day were forecast to struggle to 1C to 4C (34 to 39F), with moderate easterly winds, dropping to 0 to minus 4C (32F to 25F) overnight, bringing the risk of icy patches on untreated roads and pavements.
