It could be over 30 degrees in southern Sweden on Thursday. 

The Swedish Transport Administration is therefore reducing the speed on certain railway routes to prevent accidents.

The Swedish Transport Administration also sees a risk of bleeding asphalt and the authority urges motorists to reduce speed and keep their distance.
