Powderalert
After the fresh snow and stormy weather of the past few days, we take stock and look ahead: the big Christmas gift is on its way. In this update from Henri’s #PA2 on 19-12, we check: The current situation in the Alps Details about the pre-Christmas dump with 50-100 cm on a large scale When will it become calm and safer again?
It’s time for PowderAlert #2, a nice (early) Christmas gift! This isn’t necessarily about the first snowfall starting now, but rather about the big dump expected from the weekend onward.
In the past 24 hours, snow has fallen in much of the Alps, but the amounts were disappointing compared to the already reduced model forecasts. In this update of Powder Alert 1, we check where the most fresh snow has fallen and zoom in on the Pyrenees, where a real snowstorm is raging.
Two low-pressure systems are moving onto the continent today and tomorrow, significantly impacting the weather in the Alps. The weather models have been very erratic in recent days, making it difficult to provide an accurate snow forecast.
After a very warm period in the Alps, a strong cooling will now follow. Higher up, the snow cover grows steadily over the next few days. A nice layer of snow will fall until Thursday evening.
After the exceptional warmth of the past few days, a cold front will bring a solid cooling and a fresh layer of snow. It will get about 15 to locally 20 degrees colder and the snowline will thus drop nicely.
In the coming days, there will be quite a bit of snow again on the southern side, especially in the western part of it. More snow is likely to follow from the weekend onwards. In some regions, accumulations could reach serious levels.
We can expect some nice snowfall in the Northwest-Alps with a low snowline. Much more snow may follow over the course of next week with a south-westerly flow, but details on this are not yet known.
It’s been Powder Alert after Powder Alert in the last period and once again it’s here. The snowfall in the south-west Alps has started and it is going to s snow heavily again! Responsible is a decent low pressure area west of France.
A surprise PA with short and bright snow next night (Tuesday to Wednesday) and Wednesday during the day. Yesterday I already discussed the weather situation, but today I decided that the amounts are sufficient for PA#13 after all.
