The high mountains have snow. It is white now. The snow started yesterday. It is very cold.
This is a "sea effect." Wet air from the sea makes snow. It fell on the highest parts. This means it is cold.
The police stop some cars. Some cars can go. Others need special things. This is to stop bad things. Roads are not safe.
The weather is changing. Cold weather will stop. Skies will be clear. People must be careful.
Snow looks nice. Ice is not good. Travel can be hard. Listen to the police. Be careful in winter.
