North and northwestern Scotland will be the epicentre for much of the UK’s more dramatic weather this week, with biting showers and strong winds forecast from the Hebrides further southwest up to Durness further north.
The Met Office told this news site that wintry showers would fall across the region tomorrow, with the heavy rain turning to sleet for some.
A yellow weather warning for strong winds is also in place between 6am and 5pm on Wednesday, with forecasters warning of some travel disruption and “dangerous” coastal conditions.
Met Office meteorologist Alex Deakin said gusts of 70mph to 75mph are expected as a high-pressure system takes “control” of the weather.
“We have another one of these cold fronts heading in,” Mr Deakin said. “The winds are going to be strengthening – getting very blustery across Scotland on Wednesday.
“It will be windy throughout the day with the strongest winds likely to be in the afternoon as this weather front moves south, bringing a spell of heavy rain as well.”
The alert, covering swathes of north and northwestern Scotland, warns that coastal communities will be inundated by spray and large waves.
Delays to and cancellations of some air, ferry, train, and bus routes are also expected.
Following “plenty of winter sunshine” on Tuesday, Wednesday morning will bring fog and a hard frost to much of the country, before making way for another bright afternoon.
