Heavy hail and snow showers are expected during Monday morning and will lead to ice and snow accumulating on many surfaces. The showers will be heaviest and most frequent across parts of western and northern Scotland. Longer journey times by road, bus and train services are likely while some vehicles could become stranded.
Ice is likely to form on untreated pavements, cycle paths and roads leading to some injuries from slips and falls. Power cuts may occur and other services, such as mobile phones, may be affected.
Chief Forecaster's assessment
The cold conditions with a mixture of clear spells and wintry showers will continue through Sunday night and Monday morning. This will result in temperatures falling rapidly on Sunday evening and icy patches developing on untreated surfaces, especially where any wintry showers lead to wash off of previous treatment. Any heavier snow showers may lead to temporary accumulations of 1 cm or less at low levels whilst over higher ground, above approximately 200 m, as much as 2 to 5 cm may accumulate in a few places.
In the south west of the UK the Met Office stated Icy patches are expected to form on untreated roads, pavements and cycle paths on Sunday night and Monday morning. This is likely to lead to some injuries from slips and falls.
