The yellow warnings for icy conditions apply during the afternoon and evening of Christmas Day in parts of Götaland and southern Svealand.
The road surfaces will be slightly below zero in temperature in many places, which means that the roads may freeze, explains meteorologist Lars Knutsson.
– It is not certain that it is visible when it freezes, but could be what is called black slip – that it becomes slippery although it cannot be seen, he says and adds:
– If you are out driving in those areas and it starts to rain, you probably have to watch out.
