The differences were quite big yesterday. There were parts in the Southern Alps where the snow line hovered around 1000m, while it was still raining at 1900 meters altitude in other places in the Alps. Meanwhile, the cold temperatures arrived and it snowed heavily between Grenoble in the west and the Arlberg in the east last night. And that won't be much different today. It's snowing! In this forecast:
It's been snowing intense above 1800 meters in the Alps since Sunday night. The wind transported a lot of snow and you can find more than a meter of snow in some places. This caused the avalanche danger to go up to 'HIGH' and a lot of roads are already closed. Keep that in mind when you're travelling to the Alps. The following amounts of snow came down above 1800 meters since Sunday night:
It initially snowed above 1800 meters, but the snow line dropped rapidly yesterday evening. The cold front arrived and the temperatures dropped.
Today will be a powder day at the few open slopes or in the trees. But avoid slopes steeper than 30 degrees or slopes and trees with steep faces above them. Large spontaneous avalanches are possible, and don't forget the run out of avalanches that big!
For the first time in four days the temperature dropped below zero again in Adelboden. Thus, the temperature dropped 8 degrees in less than 24 hours time.
The cold temperatures arrived with a current from the northwest last night and this cold front causes it to snow in the northwest of the Alps today. You can expect (after the 10-30 cm from last night) another 10-40 cm of freshies during the day.
The sun will come out in the French Alps and Valais in Switzerland on Wednesday, but it will still be snowing in the northern Alps. The sun will come out over there later in the day. It will start snowing again in the French Alps on Thursday and this snowfall will expand to the north. The front arriving on Thursday is a warm front (no, definitely not as warm as the last one) and will cause a Föhn storm in the Northern Alp. Fortunately, this Föhn storm won't last long and the northern Stau will kick on right after!
Wax up, PowderAlert #5 is ON. Wednesday will be a great day in the French Alps with plenty of sunshine! It will be pretty good in Vorarlberg and the north of Switzerland on Wednesday afternoon and Thursday morning. This is the powder chase:
So happy hunting! Choose resorts with trees between 1200 and 2100 meters and with a decent base and you'll have some great days. And if you'd ask me, I would avoid the steep slopes and big faces above the 2200 meter. Leave those slopes to the avalanche dummies.
The avalanche danger got up to HIGH (4 on a scale of 5) locally. This means that you need to have the right knowledge to make the right decisions in the terrain. If you don't have this knowledge, go out with a mountain guide!
This section is highly speculative, but it looks like that it will remain dry with cold temperatures after the weekend. There's a high pressure area with mild temperatures in the forecast for the ultra long term, but again, this is speculation. Conclusion: ride powder the next 10 days!
Stay stoked, Morris
