Machine translation Read Antoine's original, in French →

Weather for the Vercofly, Saturday.

Switzerland is under the influence of the Azores High. The disturbed West current stays between Iceland and Scandinavia, but a cold front will manage to reach the north of Switzerland. On Saturday, since we are further South, the day will be sunny with cloud passages at mid and high altitude. Cumulus in the afternoon.

Wind

Ai !! That's the problem! The wind will be from the West to Northwest sector and will be moderate. We're talking 20 to 40 km/h for the 2000-3000 metre layer. (It will be stronger than Friday) There will be a Northern overpressure of 7 hPa and this can generate strong valley winds.

Thermal

Complicated with the announced wind!!

Clothes

0°C at 4700 metres Becs de Bossons between 8 and 11°C

Dangers
