There's also a more accurate localised snow report but it's written in German. However, the snow depths are easy to see and most of the relevant terms are translated below.

Schneehöhe am Berg = Snow Depth on Mountain
Schneehöhe im Tal = Snow Depth in the Valley
Griffig = Perfect
Pulverschnee = Powder
Neuschnee = New Snow
Altschnee = Old Snow...?
Maschinenschnee = Snow Machine

One thing is very apparent from checking the situation on a daily basis for the last two seasons - The weather and snow conditions in the area change so quickly and so often that you can never be 100% sure exactly what it's going to be like until you get there.
