Millions of people in Ireland and northern parts of the U.K. are being urged to stay at home as hurricane-force winds disabled power networks.

This is the first red warning issued for Northern Ireland since a new impact-based alert system was introduced by the Met Office in 2011. It is also the first time a red warning has been issued across the whole of Ireland, with Met Éireann issuing the highest level alert across the Republic.

More high winds and heavy rain are expected on Sunday as a new storm approaches the UK. The warning came as a 19-year-old man was confirmed to have died after he was hit by a tree while driving in East Ayrshire on Friday during Storm Éowyn.
