Heavy snow and strong winds will combine to lead to disruption to travel, especially over higher routes.
Valid 00:00 Monday until 23:59 Monday
Frequent and heavy snow showers will affect the region throughout Monday and Tuesday. Snow showers will occur especially over high ground, giving slight accumulations of 1 to 3 cm above 150 metres and 5-10 cm above 300 metres.
Snow will gradually build up and in a few locations, accumulations of over 20 cm are possible by Tuesday evening over the highest routes in Scotland.
The height of the snow level will vary throughout the period, but it is likely that any snow accumulations at low levels will only be temporary.
Strong winds, gusting 50-60 mph, will lead to blizzard conditions at times and considerable drifting of lying snow over high ground.
Icy surfaces are likely to occur, more especially on Monday night into Tuesday morning.
Frequent lightning strikes are also possible, perhaps leading to interruptions to power supplies.
