The deep Atlantic low-pressure system is expected to bring widespread rain northwards overnight into Tuesday, with winds strengthening as the storm moves in. Wind speeds will increase through Tuesday morning, with gusts around 50mph (80km/h) becoming widespread by lunchtime, before strengthening further into the afternoon.

Trains, flights and ferries have been cancelled and thousands left without power as Storm Bram brought heavy rain, strong winds and unseasonably mild temperatures to large parts of the UK.

"Fast flowing or deep floodwater is likely, causing danger to life," the Met Office said.
