More than 30,000 homes and businesses in Ireland have been left without power as Storm Barra made landfall.
The Met Office has issued severe yellow weather warnings across most of the UK, with the exception of the far north of Scotland.
Gale-force winds and blizzards are expected in parts of Northern Ireland, Wales and south-west Scotland later on Tuesday. Heavy snow is also expected across northern England.
The latest storm comes less than two weeks after Storm Arwen hit the UK.
If you have been affected by Storm Barra, we would like to hear from you.
