It's very hard to say - it just depends on how heavy the snow falls.
Obviously the mountain staff will be working as hard as possible to get slopes open because that's what everybody wants - they've been using piste bashers to dig out the lifts! The aim will be to have lower lifts open again tomorrow as the forecast is for the snow to slow down over the next day or two and maybe a tiny bit of sunshine tomorrow late afternoon, but the forecast also says some some every day for another week!

If the weather continues as forecast, are the slopes in Arinsal / Arcalis likely to open at all? I'm due to arrive on Sunday and definitely worried now
