Storm Arwen, named the by UK Met Office today, could see Storm Force Éireann to issue Status Yellow wind warnings for counties Donegal, Sligo and Mayo for tomorrow afternoon and into tomorrow night.
While the east coast of Scotland and the UK will bear the brunt of the storm, the affected areas in Ireland and Northern Ireland could see possible power outages, fallen trees and traffic disruption, Met Éireann forecaster Gerry Murphy told Independent.ie this afternoon.
