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.

Thousands of homes remain without power and travel disruption is continuing in Scotland in the aftermath of Storm Eowyn, which swept across the country on Friday. SP Energy Networks said its engineers had worked through the night to restore power to homes after winds of up to 100mph caused “extensive damage” to the electricity network.
