Snow has been falling steadily over Exmoor and Dartmoor through this morning, but with a pulse of heavier precipitation, that snow turned heavier and fell to lower ground too.
While 10 to 15cm is expected over the Moors, as we’ve seen in some parts, there’s been a few centimetres at lower elevations as well.
The mixture of rain, sleet and snow will continue through this morning although will become more confined to the higher ground later on as it starts to ease away to the south.

Ms Murphy has advised motorists to drive to the conditions and stick to main routes.
