Antoine's Forecast

Sunday, August 2

Machine translation Read Antoine's original, in French →

Anticyclone

Anticyclone right over our heads with not very high pressures, about 1016 hPa. I'd be tempted to say Barometric Swamp, but I haven't read that in the bulletins. A low off Ireland will turn the winds a bit more to the Southwest, which will bring us more heat than these last days. Sunday will therefore be a sunny day with cumulus overdevelopment in the afternoon possibly giving a storm in the mountains.

Wind

They'll be oriented more to the Southwest than Saturday and are announced weak to moderate. We're talking 10 to 25 km/h for the 2000-3000 metre layer. With this orientation, the Crêt-du-Midi should be less affected. (This is pure speculation)

Thermal

Higher than 3500 metres.

Clothes

Warmer than Saturday (finally a bit of heat!)

Dangers

- Cumulus overdevelopment in the afternoon possibly evolving into a storm. - In the afternoon, tendency toward South Foehn in the Haut-Valais or even in central Valais.

Info

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