[Tagging] Tagging an area for seasonal snowfall?

[Warin]

Is tagging an area for seasonal snowfall a realistic possibility?

In note that there are 2 tags regarding seasonal snow, one for road, the 
other for foot paths.

Both are status 'unspecified'.

Why? Helpfull to;
avoid if not equipped or desired
tour if desired (snow fights etc)
