A weather warning for high winds has been extended to cover Friday as the storm is officially given a name.

Earlier this week, forecasters warned of heavy winds on Saturday across all of Wales, but that warning has now been extended to cover all of the west and south west coast of Wales from 9 am tomorrow (Friday).

The weather system has officially been named Storm Arwen.

The strong winds, which could reach in excess of 65mph in exposed coastal areas may cause Injuries and danger to life from flying debris and some damage to trees, temporary structures and buildings, such as tiles blown from roofs, could happen.

Injuries and danger to life could occur from large waves and beach material being thrown onto sea fronts, coastal roads and properties

The Met Office is also warning that road, rail, air and ferry services may be affected, with longer journey times and cancellations possible.

The Met Office says: “Storm Arwen will bring high winds southwards from northern Scotland during Friday.

“Gusts will widely reach 55 to 65 mph in many coastal areas with the highest gusts in coastal parts of Scotland and Northern Ireland where gusts in excess of 65 mph are expected in some areas.”

The winds are set to get stronger on Saturday with a yellow warning covering most of the UK.

The Met Office says on Saturday: “Gusts will widely reach 55 to 65 mph in many coastal areas with the highest gusts in coastal parts of Scotland, Northern Ireland, Wales, southwest England and northeast England where gusts in excess of 65 mph are expected in some areas.

“Winds will start to slowly ease over Scotland and then northern England during the course of the day.”

As well as strong winds, Storm Arwen will also bring snow, mainly over high ground, but some sleet and snow is also possible over some lower ground in the UK later on Friday and Saturday, but this is likely to be more short-lived.

Met Office Principal Meteorologist Dan Suri said: “Storm Arwen is associated with a deep low pressure system that will impact the northeast in particular from Friday, but will also bring wider impacts to the UK with high winds, rain and some snow probable over the high ground.

“Storm Arwen’s impacts are mainly associated with high winds as the storm sinks southwards and will widely bring gusts of up to 65mph in coastal areas, although slightly stronger in the northeast, with in excess of 75mph possible in exposed locations.”
