Machine translation Read Antoine's original, in French →

Behind the cold front

This Friday's dynamic cold front is moving off towards the East. A depression over England will drive a warm front that will reach the north of Switzerland on Saturday. Saturday will therefore be a sunny day with small cumulus on the ridges and cirrus at altitude (warm front)

Wind

The wind will be from the Southwest to West sector and will blow light to moderate. In the morning, we're talking 10 to 30 km/h for the 2000-3000 metre layer and in the afternoon 20 to 30 km/h and more.

Thermal

In my opinion it's not great: cirrus + wind

Clothes

0°C isotherm at 3800 metres Crêt-du-Midi between 10 and 13°C

Hazards

- After the passage of the cold front, the air mass risks being a bit "bumpy". - If the wind turns more West it could be strong on the ridges. - Valley wind

Info

- TMA Sion inactive, but be careful because that doesn't mean there are no planes. - The Chalais-Vercorin cable car is out of service until early December.
