Meteo France has issued an orange alert for avalanches in the department and the rest of the Northern Alps.

The main alpe d’Huez road is currently blocked at virage 7 by a mudslide. Traffic is chaotic. You can probably get to resort via Allemond and Villard reculas but the road is difficult.

The Col de Montets road to Vallorcine is closed due to avalanche risk.
