And again there is something in the Southern Alps

After minor snowfalls here and there, Ullr is now bringing alarm-worthy amounts to the south again. It has already started to snow and there will be a lot by Monday. The problem with southern alerts in spring is of course the high snow line in the south, in addition to the foehn in the north.

Alert period and area

The period lasts until Monday morning and everything comes down relatively quickly. The area extends from Ticino to Slovenia and in the Maritime Alps to the Hautes Alpes and their south-western foothills. On the main Alpine ridge in Switzerland and in other parts of France, it can also be close to the alarm.

Snowfall line

This is relatively high and fluctuates between 1500 and 1800m, it may also rain briefly up to 2000m, especially on the Hautes Alpes or where there are slight SW foehn effects. With the strong spring sunshine and not quite as high precipitation intensity, I would doubt whether there will be snow further down in the Alps, as it won't cool down that much.

Wind

Will remain fairly relaxed in the accumulation areas up to the southeast, but a Föhn storm will blow on the main ridge. In the accumulation areas you can find quite good powder further up from Tuesday.

The amounts

From Ticino eastwards 30-50cm above 2000m in accumulation areas also 60cm. In the far east in the Julian Alps, there could also be 70 or 80cm.

In the Maritime Alps and in SW France, there could be 40-60cm and up to 70cm in accumulations.

Where should I go?

I would recommend a tour later today in the Maritime Alps and tomorrow in the core areas in the trees. Since the whole thing should take place above 1800m, I would also recommend the Maritime Alps, the Upper Engadine or Piedmont. In the southeast, the trees are probably not high enough. There may be gaps in the clouds tomorrow, especially in the south-west, so perhaps be prepared and look for a ski resort where both are possible.

On Tuesday, it will probably clear up in the south and you can continue powdering higher up.

Medium-term

All in all, quite usable for spring, because first there will probably be a possible südstau or southwest jam again from Thursday, but it won't be too hot either. This will probably remain most pronounced in the Maritime Alps again.

What comes next and whether it will even be really wintry again towards Easter, or wam and dry, is very unclear in the blurry crystal ball, but of course it helps to call the models that show it at the Ullr shrine and push Ullr in the right direction.

Powder to the people!
