"Surely some mistake?" That's what we thought when we saw the Welove2ski snow forecast on Friday, June 18. It was predicting up to 50cm of fresh snow in parts of Austria and Switzerland for today, June 20. But that's exaclty what they've got.

Looking along the Ziller Valley from the Tux glacier in Austria, June 20. It looks as though there's snow all the way down to the valley floor.

We're finding it hard to get decent webcam pictures of the scene there this afternoon. Most are shrouded in cloud. But it's clear there's been heavy snow - and the forecast is that there's more to follow. At one glacier, the Stubai, south of Innsbruck, they're reporting 20cm of snow on the valley floor and 50cm of powder higher up! When the skies eventually clear there'll be a Midsummer powder party...

It's not just Austria that's seen the snow. Some of the heaviest falls have been in the high and remote Engadin Valley in south-eastern Switzerland (pictured below), which is home to St Moritz.

There's also been snow at altitude nearby in Italy, in the resort of Madonna di Campiglio, and even a 5cm dusting on the glacier above Tignes in France - which opened for summer skiing on Saturday.

The Plauns campsite near St Moritz in Switzerland, June 20. Anyone for a barbecue?

Needless to say, we hope someone will get their video camera out and send us some inspiring summer-skiing footage when the sun comes out. Though they'll have to be quick. By Wednesday the cold snap will be over and temperatures look set to return to something as little more summery.
