Yellow warning for snow and ice issued across Ayrshire
Between TUE 00:05 and Wed 23:55
Heavy snow showers are expected on Wednesday.
There is the potential for travel delays on roads, with some stranded vehicles and passengers, as well as delays or cancellations to rail and air travel.
Some rural communities could become cut off. Power cuts may also occur and other services, such as mobile phones, may be affected.
Chief Forecaster's assessment
Showers will bring a large variation in amounts of snow across even small areas with some places seeing very little snow.
There is the potential for 10-15 cm of snow in places where showers become more frequent whilst nearby locations may see much less frequent showers and only small accumulations of 1-3 cm in places.
Strong winds will lead to drifting of snow, and lightning could be an additional hazard, particularly near North Sea, Irish Sea and English Channel coasts.
By the end of Wednesday, more than 20 cm may have accumulated in places in some eastern counties of England, Scotland and Norther Ireland from a culmination of Monday, Tuesday and Wednesday's snow showers.
