The Met Office has issued a yellow 'be aware' weather warning for snow and ice across Carmarthenshire and much of Wales.

The warning says: "Snow showers are expected to develop from Wednesday evening lasting into Thursday. These, combined with strong winds, could lead to locally very poor travel conditions."

The Met Office is calling on people to be aware of the potential for disruption to transport due to lying and blowing snow.

It goes on to say that cold air originating over Arctic Canada will affect the area from Wednesday evening through Thursday, bringing snow showers and strong winds.

Wind gusts up to 55 mph are expected in exposed coastal areas and on hills in association with snow showers, leading to temporary blizzard conditions.

As well as reduced visibility, two to five centimetres of snow could accumulate anywhere within the warning area, with 10-20 cm possible above 300 m. Lightning may accompany the heaviest showers, with potential disruption to power supplies as a consequence.
