A good 30cm during the night (I'm delighted to say....).
It's still snowing and forecast to carry on all day. Might be interesting getting down the mountain and back up this evening to pick up #2 daughter from Geneva airport.
Still, I have snow tyres, and 4WD, plus chains if necessary. The only issue is if the road gets blocked.
Well it's still snowing, and the Gendarmerie insist that everyone dons chains, regardless of Snow tyres, 4WD etc. So, I've just popped out to the garage and fitted them. The ones I have are a Maggi Trak Autos - fantastic Italian chains which pretty much put themselves on. Here's a video of the fitting procedure (you can skip the first 80 seconds as the faffing about with spacers bit you only have to do once when fitting them for the first time).
