Millions of people in Ireland and northern parts of the U.K. have heeded the advice of authorities to stay at home.

Emergency crews are cleaning up after a storm bearing record-breaking winds left at least one person dead and more than a million without power across the island of Ireland and Scotland.

Record high winds from Storm Eowyn battered Ireland and Northern Ireland on Friday, leaving one man dead and almost one-third of Irish homes and businesses without power and forcing the cancellation of hundreds of flights.

The storm had knocked out power to more than half a million utility customers by early Friday as it moved across Ireland.

Earlier red warnings covered the entirety of Ireland and Northern Ireland. Now the most serious alert covers parts of Scotland as the storm brings winds posing a danger to life.

A powerful "bomb cyclone" named Storm Éowyn (pronounced AY-oh-win) will pummel parts of Ireland and the United Kingdom with fierce winds and heavy rainfall on Friday, and it has roots in the historic winter storm that just hit the U.S. Gulf Coast Tuesday.

The storm brought 100 mile-per-hour winds to the island and also battered Scotland and northern England. Britain’s weather office issued a red warning, its highest level of alert.

Storm Eowyn Friday continued to cause power outages for hundreds of thousands, knocked down trees and disrupted transportation as it moved across Scotland and Northern Ireland into Britain's West Midlands region.

Buildings are damaged and 100,000 homes and businesses are left without electricity as gusts over 100mph are recorded.
