A yellow alert for snow has been issued for northern Scotland on Friday, but currently this is not expected to reach areas further south than Oban.
A Met Office statement said: “Warm air crossing the Atlantic will encounter very cold arctic air which will cause a low pressure system to develop later on Wednesday.
“This low pressure will then deepen rapidly on Wednesday night and Thursday morning, tracking quickly eastwards to the north of Scotland as it does so
“ As this system moves eastwards into Scandinavia it will to bring very strong westerly winds to northern and central parts of the UK during Thursday.”
SEPA has issued a coastal flood alert, adding: “A combination of severe gale force winds, tidal surge and high astronomical tides are expected early on Thursday morning.
“Large waves and spray overtopping are expected in western areas. Flooding to low lying ground is possible in exposed coastal areas.”
