The weather on Wednesday will be globally disturbed, with four departments in orange rain-flood vigilance, Savoie, Haute-Savoie, Ain and Isère, and high avalanche risks in Haute-Savoie, according to Météo France.

In the four departments in orange vigilance, "the soils are already well saturated" following the heavy rains.

And "the risk of an avalanche is strong on all the massifs of Haute-Savoie", adds Météo France in its 06:00 bulletin.

Many avalanches expected

"Many avalanches of wet snow will be triggered this Wednesday with the return of the rain, which can take the entire snowpack in place. These avalanches may reach exposed road sectors as well as mountain infrastructures", warns the 'agency.

Overall, the weather is expected to be rainy from the north of the Alps to the Belgian border and to Normandy in the morning.

The precipitation will remain quite marked near the alpine relief, with snow from 900 meters in the interior valleys in the first part of the day.

This rain-snow limit will rise significantly over the hours.

From the South-West to Brittany the clouds will be numerous in the morning and will give light rain.

Return of the sun in the south

In the afternoon, an improvement will emerge south of the Garonne with clearings.

The rains will also weaken from the Massif Central in the north of the country while the disturbance will block from the Alps to Alsace, still bringing rainy weather.

Around the Gulf of Lion and in Corsica, the weather will remain dry and cloudy.

The westerly wind will still be strong from Brittany to the Belgian border with gusts between 60 and 80 km / h.

The Tramontana will remain sensitive in its domain, as well as the west wind on the coasts of Provence.
