I'm in Santiago. It's been snowing on and off in the mountains for the last few days now. This is a photo of the foot of the Andes from my flat (obviously the resorts are quite a bit higher than this):
I'm not sure how much has fallen in Valle Nevado, probably only about 10/20 cms but there's another meter of snowfall at the top of Valle Nevado forecast for this week. This time last year they'd already had over a meter of snow and quite a few people have been saying this season won't be great. Have you thought about going to Portillo? Pretty much guarenteed to get better conditions there, and it's beautiful; amazing BC too.
If you have any q.s send me a PM and I'll try and answer them.
