According to the Laws of the Game it is for the referee to decide whether or not a match can take place when the weather is too severe. But what defines the term "too severe"? Are there any guidelines about wind speed, snow, rain fall, etc. the referees have to follow?
Right now we have wind speeds of >120 km/h, which would in my opinion way over the limit, but what actually defines that limit? In our referee group we had a test for that, but that was just a small guidance for our local league (like can you see both goals from the middle line or can you run on the pitch or is it too deep, etc).
