Heavy snow is expected to fall across Wales and southern England later, bringing travel disruption for the evening rush hour.
The Met Office has upgraded weather warnings from yellow to amber for heavy snow between 14:00 to 21:00 GMT.
Meanwhile, temperatures have fallen to the lowest level this winter, with Braemar, Aberdeenshire, dropping to -14.4C (6F) this morning.
It is the lowest in the UK since -15.6C in Holbeach, Lincolnshire, in 2012.
The Met Office warns the heavy snow could cause:
- Travel delays on roads which could strand some vehicles and passengers
- Some delays and cancellations to rail travel
- Rural communities could be cut off
- Power cuts are likely and other services, such as mobile phone coverage, could be affected
What’s the forecast?
Further snow is forecast overnight into Friday, with up to 15cm (6in) possible in some parts of Wales.
In southern England, there could be 3-7cm (1-3in) of snow.

BBC Weather presenter Simon King said rain, sleet and snow would cause disruption for Thursday evening’s rush hour across the south west of England.
Mid and south Wales will also have snow, and it will move into central and southern parts of England, and into south east England.
The north east of England and north Scotland will also see snow showers and cold temperatures on Thursday night.
England, Wales and Northern Ireland have also recorded their lowest temperatures this winter with:
- Redesdale, Northumberland, falling to -10.4C (13.3F)
- Sennybridge, Powys, dropping to -9.3C (15.3F)
- Magilligan, County Londonderry, falling to -8.5C (16.7F).
On Thursday morning, Southeastern Trains said 21 trains were cancelled or altered to minimise the impact of ice forming on the rails.
It will run its “winter weather timetable” on Friday – with passengers warned of peak services being busier than normal because of changes to some train times.
