THE Met Office is warning snow is on the way tonight.

A yellow weather warning has been updated to make a dual snow and ice warning from this evening and throughout tomorrow.

The warning which begins at 5pm, covers Carmarthenshire, Neath Port Talbot and Swansea areas.

The Met Office says: “Showers, a mixture of rain sleet and snow, are expected to fall onto frozen surfaces leading to icy stretches forming. In addition, a more persistent spell of rain and hill snow is likely to move south during Thursday evening and night.

“This then gradually moves into parts of central and southwest England and southeast Wales on Friday.

While ice is expected to be the most widespread hazard, snow is likely in places too. Snow is most likely to fall over The Pennines, North York Moors and the high ground of Wales and southwest England, with 2-5 cm possible here.

“Elsewhere, while some snowfall is possible, accumulations are likely to be slight and temporary. Freezing fog patches are also likely to persist and may prove an additional hazard with areas of visibility less than 100m at times.”
