PowderAlert 6 2017/18 | Dumps from the assembly line

Ullr's next delivery

by Lars Oelmann 12/07/2017
Ullr apparently wants to make this December unforgettable and sends one dump after the other. No end in sight in the coming week! It will get warmer from time to time, but the snow will keep falling down to below 1000m, so from 1000-1200m there should actually be a positive total. The next alert comes on Sunday, but more on that in the medium term.

Timeframe

Until Saturday evening. But most of it will fall by Saturday noon.

Areas

Hautes Alpes to the Arlberg, and the core is from the Belledonne to the western Lower Valais. There will also be a few centimeters further east, which can be used on the base, but it will probably remain below the 30cm alert threshold.

In the southeast, there could be a sprinkle in Slovenia and Carinthia, but I think the flow turns too quickly to the north and that goes into the Balkans.

Snow line

Starts this morning (Friday) at 1300-1700m. In the classic, west-protected valleys such as the Rhone Valley, it is also snowing lower.

But it quickly drops to below 1000m everywhere. The full amounts come from 1800m, with a good 75% coming below 1000m.

Wind

Will be quite uncomfortable as Ullr sends in a fairly aggressive trough from the north and causes a decent storm at the top. So be careful in the short phase on Sunday when you can get above the tree line!

The amounts

From the Arlberg down to the Hautes Alpes, everything west will get 35-60cm. The strong current should also unload a lot deep into the Valais. In the core, this can also be 70-80cm depending on the jam, especially in the Belledonne or on the France/Switzerland border.

Where should I go?

Into the trees if they are drivable, otherwise onto the mountain pastures on Saturday. After this alert, there should be enough in the forest too.

On Sunday, you might be able to look further up in the north in the short weather window, while it's already starting to snow again in the far west.

Mid-term

A new alert is coming on Sunday, because it's snowing a lot more. Unfortunately, warm air will also push in because there will be a südstau, which will then turn north again as the low passes through. So don't worry: the Föhn should only briefly consolidate everything in the north, while the south will be blanketed.

It looks good! Ullr apparently wants to pack the last three winters into one, because with what is calculated there, we will have greater snow depths in mid-December than the last few years at the maximum.

Powder to the people!
