Well, this is a sign that the road is only for people walking, no cars.
This afternoon, evening and night, and perhaps the whole weekend, there will be stronger winds than a storm, so it is probably best to stay inside if you live in the area on the west coast of Norway.
It might be very difficult to just stand up or walk outside.

I am working this weekend, and wonder what will it be like to be outside in my little Fiat 500C. ??!!
