The Met Office says very strong winds will affect parts of the UK early on Thursday. The strongest winds are expected to transfer eastwards across the warning area, before clearing by mid-morning.
Road, rail and ferry services may be affected, with longer journey times and cancellations. There is also a possibility that some bridges may close.
Power cuts may occur, and there is the potential for other services, such as mobile phone coverage, to be affected.
Injuries and danger to life from flying debris are possible, along with some damage to buildings. In addition, large waves are expected to affect some western coasts with beach material being thrown onto sea fronts, coastal roads and properties.
A gust of 93mph has been recorded at Capel Curig in Snowdonia. A gust of 78mph was recorded at Aberdaron 76mph at Lake Vyrnwy and 74mph at Aberporth.
A 30ft tree has come down onto the back of a house at Llanelly Hill near Brynmawr.
There are restrictions on Severn Bridge because of the strong winds.
