Météo-France calls for caution near the Belgian border
During the night from Friday to Saturday, a new Atlantic disturbance, rainy and very windy, will arrive from the west, watering mainly the north-west of the country.
The wind will be strong enough.
On Saturday, in connection with the Justine depression, the disturbance that arrived the day before from the north-west will give often moderate rainfall in the morning, from the Pyrenees to the north-east and north.
But Météo-France calls for caution near the Belgian border, where snow will mix with rain.
With the cooling at the end of the day, a thin layer of snow on the ground is possible in the Nord-Pas de Calais, under a moderate easterly wind.
In the west, after a slight lull, the rains will resume at midday, with the wind at times quite strong.
The gusts will reach 80 to 90 km / h in the Atlantic regions, temporarily 110 km / h on the coast at the end of the day.
Be careful, strong waves are to be feared at the end of the day on the coasts of Finistère and Morbihan.
During the day, the rainy weather will block in the east of the country, as far as the east of Provence, with a rain-snow limit which will drop from 1,800 to 1,300 m.
A few thunderstorms will break out near the Côte d'Azur and Corsica.
The wind will remain strong at the edge of the Mediterranean, with a tramontana at 100 / 110km / h in the afternoon, and peaks at 100 / 130km / h on the Corsican capes at the end of the day.
Showers will increase in the southwest.
It will snow at around 1,300 m in the middle of the day in the Pyrenees.
The west wind will also blow quite strongly at the foot of the Pyrenean massif.
Temperatures will be stationary and always mild, with 5 to 11 degrees for the minimum, locally 12 in the Southwest.
Maximum temperatures will drop slightly from 7 to 13 degrees in the northern half and 11 to 15 in the south, to 16/17 in the extreme southeast.
