Do follow resort safety advice, road closures and path closures wherever you are in the Savoie, Haute Savoie or Isere regions. Here is a video of a Val d’Isere avalanche running across footpaths, a car park and approaching a building. Danger rating 5 is associated with risks in the resort as well as on the mountain.
The reason the danger is so high is the combination of wind loaded slopes, huge snowfall and a sudden rise in temperature this morning. This causes large natural spontaneous avalanches.
