Storm Barra is expected to bring ice, wind and rain – which could cause flooding for parts of the UK on Wednesday.
Dozens of flood warnings have been issued across the UK, while communities in the North East and Scotland begin to recover from the catastrophic effects of Storm Arwen.
Thousands of homes lost power for up to 10 days in the wake of 100mph winds and lashing rain at the end of November.
Northern Powergrid has not confirmed whether all homes were connected by Tuesday night as promised.
Storm Barra moved in from the west on Tuesday, and a yellow weather warning for wind is in place until 6pm on Wednesday for the west coast of Wales and south-west England.
Aberdaron in Gwynedd, Wales, which is covered by the warning, was battered by gales of 86mph on Tuesday, while Orlock Head in Co Down, N Ireland, faced 76mph gusts.
Met Office forecasters said Storm Barra is not expected to cause as much chaos as Storm Arwen – though it has already sparked travel delays and school closures in Scotland.
