Hi David,
Haven't been there...... sounds very
Are they forecasting storms for several days? You're obviously the wrong side of the border! Forecast is still quite reasonable on the French side. If it clears up, see if you can go and have a look at the Croix du Coeur - a strip not too far to the South near Verbier at 7100ft. It's a beautiful spot, and there must be someone at Bex who can take you there.
When are you heading back to the UK?
