The yellow warning will be in place overnight and carry through into tomorrow (Sunday, March 10) morning.
Forecasters say this is due to an area of rain that is likely to turn to snow over a central swathe of the UK.
Highest snowfall accumulations will tend to be over hills and mountains where a ‘few centimetres of snow’ are likely.
But below 200 metres, ‘only 1-2 cm or so of snow’ is likely.
It may be that places in the far south as well as the far north of the warning area see little or any snow.
Some roads and railways are likely to be affected with longer journey times by road, bus and train services.
Keep checking back for updates.
