Antoine's Forecast

Saturday, August 1

Machine translation Read Antoine's original, in French →

Barometric swamp

Our country is South of a low positioned over the North Sea, which was responsible for the small cold front that hit us on Friday. On Saturday, we will be in a barometric swamp situation with an unstable air mass. The day will be sunny after the residual clouds dissipate. In the afternoon, cumulus will build and storm cells could develop over the mountains.

Wind

The wind will be light to moderate from a South-West or even West sector. We are talking 10 to 30 km/h for the layer from 2000 to 3000 metres.

Thermals

You don't go thermalling with big "puffy ones" (cumulus congestus or cumulonimbus)

Clothes

Cold won't be the problem of this day.

Dangers

I see several dangers for Saturday. - If the wind turns a bit more to the West, it could be too strong at Crêt-du-Midi. - The valley wind could be strong too. - The build up of cumulus which could turn into storm cells and cause big gusts of wind.

Info

- TMA Sion inactive, but watch out because that doesn't mean there are no planes. - The Chalais-Vercorin cable car is out of service for several weeks.
