In its mid-range forecast, the Met Office said: “A northwest-southeast contrast in weather patterns is likely across the UK at the start of the period.
Met Office Deputy Chief Meteorologist Chris Almond added: “Although no longer a named storm, the remnants of Ex-Tropical Storm Alex will bring some strong winds across the northern half of the UK – especially to Scotland and Northern Ireland on Friday and Saturday.
“The track of the low-pressure system currently looks to be off the northwest coast of the UK on Friday and Saturday and winds are likely to reach around 45mph for some parts of the north of the UK, with a chance of some gusts in excess of 55mph in some exposed northwestern islands and coastal areas.”
