Yellow warning
Wind between and Show detail

Description

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, with the potential to affect other services, such as mobile phone coverage. 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. This is an update to the warning, shrinking the yellow area and also the validity period.

Chief Forecaster's assessment

Gusts of 50-60 mph are likely quite widely. There is some uncertainty over the peak gusts, but there is a small chance of winds reaching 70 mph in places - most likely across coastal north Wales and northwest England during the middle part of the night and then across parts of Lincolnshire and East Anglia early on Thursday morning.

Yellow warning
Snow & ice between and Show detail

Description

Heavy snow showers will continue through Thursday and Friday, although perhaps more of sleet and hail near some coasts. Over exposed high ground, snow will drift in the strong winds. Travel delays on roads are likely, as are public transport cancellations. There is a chance of power cuts, while services such as mobile phone coverage may be affected. A few rural communities may become cut off. In addition some roads and pavements will turn icy, increasing the chances of accidents or injuries.

Chief Forecaster's assessment

Snow showers will be heaviest and most frequent across western Scotland, where high ground is likely to see a further 10-20 cm building up above 200-300 metres. There may also be more than 15 cm over the high ground of Northern Ireland and northern England. At low levels, parts of the warning area will see 3-10 cm of snow, with some places near the west coast seeing very little. Showers will be accompanied by hail and lightning at times, particularly across western Scotland. Here, in particular, there is potential for disruption to power supplies from lightning strikes. Strong winds bring the potential for temporary blizzard conditions and drifting of lying snow, mainly over high ground.
