Storm Dave is set to sweep across the UK from west to east overnight on Saturday, driving the wet and windy weather.
Met Office chief meteorologist Chris Bulmer said “people should be prepared for impacts with disruption to travel likely and possible power cuts”.
“Wind speeds will peak at different times as the deep area of low pressure moves across the north of the UK, with peak gusts in Northern Ireland expected earlier on Saturday afternoon before spreading more widely across the north of the UK,” he added.
Up to 30cm of snow could fall in Scotland, the Met Office said, with “strong wind blizzards and drifting snow” likely to be a hazard.
ScotRail has advised passengers to check their journeys before travelling, while National Highways said people should plan ahead and adjust when they hope to travel.
In total, the six separate warnings are:
An amber wind warning covering southern Scotland, northern England and north-west Wales from 19:00 to 03:00 on Sunday
A yellow wind warning covering all of Northern Ireland from 14:00 to 03:00 on Sunday
A yellow wind warning covering northern England, southern Scotland and northern Wales from 17:00 to 07:00 on Sunday
A yellow wind warning for almost all of Scotland from 18:00 to midday on Sunday
A yellow snow warning covering the west Highlands, Argyll and the Western Isles from 14:00 until 03:00 on Sunday
A yellow wind warning for Orkney and Shetland from midnight on Sunday until midday
Winds are set to ease on Sunday with a calmer Easter Monday predicted.
It is the second storm of the year, following on from Storm Chandra which hit the UK in late January.
