Antoine's Forecast

Sunday, August 9

Machine translation Read Antoine's original, in French →

Anticyclone and storm

The Azores High shifts East over Belarus. A low over the Atlantic causes a more humid and more unstable South-West flow for Sunday. Sunday, a few high altitude clouds in the morning, then overdevelopment of cumulus with probably storms over the Alps at the end of the day.

Wind

The wind is South-West sector light to moderate We're talking for the 2000-3000 metres layer 10 to 15 in the morning and 15 to 30 in the afternoon.

Thermal

With this much instability... it's not great.

Clothes

Very hot

Dangers

- Overdevelopment of cumulus that could degenerate into a storm. - Strong gust of wind possible. - With South-West, it costs nothing to check the beacons in the Haut-Valais to know if there's a tendency towards foehn from the South.

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 for several weeks.
