Thundersnow captured in Storm Goretti

This shows the rare weather phenomenon of thundersnow, captured on a doorbell camera in Crymych, Pembrokeshire - as Storm Goretti brought lightning and snow at the same time.

In Pembrokeshire, the council said on Thursday night that snow ploughs and gritters were facing "extremely challenging conditions", with ploughing "becoming unsafe at times for our crews leading to accidents, and therefore we may postpone actions to ensure the health and safety of our staff".

Some rail services have been cancelled through to the end of Friday, with passengers advised to check before travelling.
