10,000 without power in Pembrokeshire and Carmarthenshire
Work is underway to restore power to more than 10,000 households in south Wales following heavy snow.
Areas most affected are Pembrokeshire and Carmarthenshire, but Swansea, Bridgend, Cardiff and the south Wales valleys are also hit.
Phil Davies, network services manager for Wales with Western Power Distribution, says crews are out trying to fix the problems but are having difficulties getting to scenes of faults due to the road and weather conditions.
Here, he talks with Bethan Rhys Roberts on BBC Radio Wales.
