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.

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.

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.
