A rare “stay at home” warning has been issued for parts of the United Kingdom and Ireland as a severe storm lashes the region, bringing dangerous 100mph (160 kmh) winds and unleashing travel chaos.

A​ powerful "bomb cyclone" named Storm Éowyn (pronounced AY-oh-win) has pummeled parts of Ireland and the United Kingdom with fierce winds and heavy rainfall today, and it has roots in the historic winter storm that just hit the U.

Storm Éowyn has been named by the Met Office and will bring severe gales to parts of the United Kingdom on Friday. The Met Office has issued yellow warnings for wind on Friday and Saturday.

Coastal areas in south and southwest England and most of Wales are on alert ahead of a major storm system that has triggered warnings of dangerous conditions and disruption across the UK and Ireland.

As the clean-up from Eowyn continued, Ireland's ESB Networks said it had restored power to 366,000 homes, farms and businesses by Saturday evening but that 402,000 still had no electricity. In Northern Ireland, approximately 140,000 homes remained without power by late afternoon, said electricity provider, NIE Networks.
