Snow

Oh, the weather outside is frightful.

The minimap when snow is present.

Snow is a weather effect that comes into play in December. When movement is made through the snow, a trail is left behind, including when you enter or leave a building. The message shown is as follows:

You lurch/walk through the snow, leaving a trail of footprints behind you.

If footprints have already been made, then it becomes "following a trail of footprints."

You leave the building, making a trail of footprints in the snow.

Building Description

When standing outside a building, it's description is also altered. for all buildings there is the text:

Thick snow covers the ground.

If anyone has entered the block since snow covered the ground, the full stop of the previous stament is replaced by a comma and the following message appears:

with footprints entering from the x.

When x is the direction in which you travelled.

If anyone has left the block since snow has covered the ground, the previous full stop is replaced by a comma and this stament appears:

and leaving to the x.

If anyone has left the building, then the following message appears:

A set of footprints leads out of the building.

If anyone has entered the building, the stament above changes to:
