Storm Agnes has been named by the Met Office as the deep area of low-pressure that will impact much of the UK on Wednesday and into Thursday.
Storm Agnes will move into western areas of the UK and Ireland on Wednesday, with the strongest winds most likely on Irish Sea coasts, though it will be a widely windy day across the UK.
A Yellow Warning for wind has been issued for a large area of the UK. Warnings will continue to be reviewed in the coming days as the exact track and strength of Storm Agnes becomes clearer.
The wind warning highlights the chance of some damage to building from strong winds, as well as the possibility of power cuts for some. Transport disruption is also likely, with some roads and bridges likely to close.
Storm Agnes is the first named storm of the storm naming season, which runs from September to August the following year.
Today (Tuesday, September 26) - expect showery outbreaks of rain across Wales, sometimes heavy with a risk of thunder during the morning. Turning drier by the afternoon with some bright spells. Breezy, particularly at western coasts, but easing later.
Tonight, it will stay mostly dry this evening and overnight with the odd isolated shower. Some mist and fog patches developing but becoming breezier from the west by dawn and feeling cooler.
On Wednesday - after a settled start, winds soon picking up to leave a very windy day accompanied by some outbreaks of heavy rain throughout, perhaps persistent in the evening.
It is expected to be drier on Thursday with bright interludes possible. Further spell of rain arriving overnight into Friday though clearing to leave a few showers. Settled on Saturday. Less windy.
Met Office Chief Meteorologist Steve Ramsdale said: “While the precise track and depth of Storm Agnes is still being determined, there’s a high likelihood of wind gusts around 50 to 60mph for some inland areas. Exposed coastal areas could see gusts of 65-75 mph with a small chance of a few places seeing around 80mph.
“As well as some very strong winds for many, Storm Agnes will also bring some heavy rain, with the highest totals more likely in Scotland, northern England, Wales and Northern Ireland.”
