Ireland has been warned to batten down the hatches as Storm Caroline steams across the Atlantic towards the country.
Scotland is due to bear the brunt of Storm Caroline but shortly after 2:00pm on Tuesday, Met Éireann issued the weather warning of wind for counties Donegal, Galway, Leitrim, Mayo, Sligo, Clare and Kerry.
A Met Office statement said: "Storm Caroline is expected to bring a spell of very windy weather to northern Scotland on Thursday". Strong northwest winds may cause drifting of the snow in places with blizzard conditions possible at times across northern Scotland.
Winds of 100 to 110km/h are expected with the strongest winds being in coastal areas and over high ground.
The warning was issued today (Tuesday) at 2pm and applies for a 15-hour period tomorrow from 3am to 8pm.
Friday will also be cold, Met Éireann said, with sunshine and scattered rain, hail, sleet and snow showers, and temperatures of 3 to 6 degrees in gusty northwesterly winds.
A yellow "be aware" warning is in place for Scotland between 08:00 and 23:55 on Thursday.
It added: "Not everyone will get snow".
Met Eireann has issued a Status Yellow alert for several parts of the country as the violent storm approaches.
Scotland's mountain ranges, including the Cairngorms and Glen Coe, have already seen heavy snow falls in recent weeks.
Travel disruption is predicted across Thursday, Friday and Saturday.
