While the first big snowfalls of the season are causing a stir here in Germany, dozens of volunteers are mercilessly trampling the first snow of the winter in Aspen. Shoes and trouser legs wrapped in Ducktape, they march through the freshly snow-covered terrain to prevent the early season snow from becoming an old snow problem.

Now that our colleague Orakel has already spoken twice, it's high time for the WeatherBlog to dive back into the action. The weather has a lot to offer at the moment, so we'll take a classic look at the current situation and the outlook for the future.

ORF reports: "The winter weather is forcing changes to the supersonic training of army fighter pilots. The noise of their exercises could trigger avalanches in the snow-covered high Alps. The flights have been moved to the north and north-east of Austria."

At a meeting in summer 2017, the European avalanche warning services decided on changes to the hazard level matrix and the nomenclature of avalanche sizes.

The Caviahue ski resort in the province of Neuquén, which is rather unknown even within Argentina, offers a selection of impressively flat pistes nestled in a volcanic lunar landscape. The Caviahue volcano is interesting as a smoking ski tour destination, while the surrounding terrain mainly offers sled-access potential.

This year, the weather is once again following the perceived trend of "bathing weather at Christmas, snow at Easter" and is generally "april" for the Easter weekend. Why is it often so unstable in April?

The unsettled weather continues for the time being. After the very warm weekend, temperatures have now dropped back to a level appropriate for the time of year and the April weather is living up to its reputation with a mix of showers, clouds and a few hours of sunshine.

This week's WeatherBlog takes its cue from the recent snowFlurry and looks at why humidity is relevant to spring firn. The weather is and remains rather dull, with plenty of sunshine throughout the Alps before it gets a little more unsettled at the weekend.

As PowderAlert has already explained in more detail: it's snowing heavily in the southwest. In the north-east, it's only snowing a little today, then spring will continue. This basic constellation won't change much over the next few days either. What's more: tomorrow is World Weather Day!

Spring has arrived in the Alps and the high pressure weather will continue until the end of the week. Towards the weekend, it will become much cloudier with precipitation on the northern side of the Alps. We are also looking at Storm Stella, which is currently affecting the US East Coast.

Atlantic lows continue to slide from the northwest towards Central Europe and determine the weather in the Alps. After the heavy foehn event at the weekend (wind peaks of 224 km/h on the Lauberhorn, Switzerland) and accumulated precipitation in the south, there will be almost continuous precipitation in the north this week.

At the meteorological start of spring, it's getting wintry on the southern slopes of the Alps. The rapid change of mild, partly foehn-like weather on the front of the trough, followed by the fronts last night and today during the course of the day, is causing a turbulent PowderAlert with interesting amounts of fresh snow, but also strong storms.
