The weather warnings that are in place for Glasgow and the wider Strathclyde region have been extended by the Met Office.
The first yellow weather alert for snow and ice covered 3am until 3pm today (Sunday), followed by a further warning between 6pm tonight and 10am tomorrow (Monday).
However, the UK's national weather service is now predicting that snow and ice could arrive in the city from 3pm onwards - and extension of three hours from the original warning.
As well as the start time being brought forward, the warning has also been extended to cover more or northern and eastern Scotland.
The update notes that "an area of rain, sleet and snow will move south through Sunday night with the potential for icy surfaces and some travel disruption".
While the full forecast contained within the new bulletin reads: "A band of rain, sleet and snow followed by wintry showers will move south across western and central parts of Scotland and Northern Ireland on Sunday evening and then into parts of northern England and north Wales early on Monday morning.
"Localised accumulations of 1-3 cm are possible to lower levels but higher accumulations are likely over higher ground. Above 250 metres, accumulations of 5-10 cm are possible. Skies are expected to clear from the north overnight and widespread ice is likely to develop and persist through to Monday morning, especially across central and eastern areas."
The Met Office is also advising the public to expect longer journey times by road, bus and train services and some icy patches on some untreated roads, pavements and cycle paths.
