Storm Éowyn – pronounced “ay-oh-win” – will undergo rapid development during Thursday as it moves across the Atlantic
While some of the details may still change, depending on the exact track Éowyn takes in the UK, the strongest winds on Friday are likely across parts of Northern Ireland, southern Scotland, northern and western areas of England and Wales.
The Met Office warns of gusts between 80-90mph (129-145km/h) around hills coastal areas of the Irish Sea.
But widely gusts of 60-70mph (97-113km/h) are expected through the day.
Elsewhere, across northern and western Scotland, parts of the Midlands and southern England, gusts of 50-65mph (80-105km/h) are expected but around coastal areas up to 80mph (129km/h).
Met Office yellow warnings are likely to be adjusted and possibly upgraded ahead of Friday.
These gales and severe gales are likely to bring travel disruption and some damage, which could include roof tiles being blown off and power cuts.
Large waves are also expected with coastal overtopping.
Outbreaks of rain are also expected and while it will turn milder for some – especially in the south – it will remain cold enough for snow to fall over hills in Scotland, northern England and Northern Ireland.
