The warning is in place from 6pm on Monday and runs until 10am on Tuesday.

Ben Sheridan, of the AA, said: “Thawing snow, rainfalls and freezing temperatures overnight lead to challenging driving conditions, with roads likely to be icy in the morning.”
But the AA added regional restrictions which have been imposed due to Covid-19 means that roads are quieter than normal.
Large swathes of London, the Midlands, the South, South West plus the east of England and Wales have also been warned that snow and ice could hit on Wednesday and Thursday.
The Met Office yellow warning suggests that up to 2cm-5cm of snow could fall across parts of southern Wales, central and southern England, and there is a small chance of 10cm-15cm settling in a few places, most likely on high ground above 200 metres.
