Antoine's Forecast

Sunday, August 23

Machine translation Read Antoine's original, in French →

British High

On Sunday, Switzerland will be under the influence of a high over England. The Portuguese low will make itself heard between Monday and Tuesday. Sunday will therefore be a well sunny day with some cirrus (high altitude clouds) and small cumulus.

Wind

The wind will be from the West sector and will be moderate in the mountains. For the 2000-3000 metres layer, we are talking 10 to 35 km/h in the morning and 20 to 35 km/h in the afternoon. Little reminder: when MeteoSwiss says moderate, that can mean gusts up to 50 km/h in the mountains

Thermal

Not much thermal and above all wind at altitude.

Clothes

0°C isotherm at 3700 metres Crêt-du-Midi between 11 and 15°C Chalais between 15 and 27°C

Dangers

The West wind could be Sunday's problem. You'll need to watch the wind beacons closely! Watch out, as always, for the valley wind on the plain.

Misc

Here's what you can get an AI to say about wind. Pretty dumb, right? ;-) "The wind, like a wolf, prowls around the pilot, Even if he doesn't feel it, he must listen for it from afar, For it's by watching for it that he avoids its bite." Pffffff.............

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.
