Thirty-two departments, including Paris and the entire Ile-de-France, are now placed on snow-ice orange vigilance due to a snowy episode, Météo-France said on Saturday.
Orange vigilance has been extended to six departments: Ain, Allier, Cantal, Loire, Haute-Loire and Puy-de-Dôme.
It already concerned 26 departments from Pas-de-Calais to Corrèze, passing through Ile-de-France to the Rhône.
The first snowfalls were underway on Saturday morning, especially towards Upper Normandy and the west of Ile-de-France, with also some freezing precipitation from Mayenne to Loiret and Seine-Maritime.
After the generalized morning frosts and the first snows, we wait for the establishment for a few hours of more substantial snowfall. The expected quantities are between 1 and 3 cm, locally 5 cm, particularly in Ile-de-France, even occasionally between 5 and 10 cm in the most eastern and northern areas.
During the afternoon, this precipitation will then be in the form of mixed rain and snow, or even temporarily some freezing precipitation, before a sharp increase in the end of the day.
In the eastern regions, the episode will begin in the middle of the afternoon and will continue in the first part of the night. 5 to 10 cm are expected, a freezing episode is also possible during the night in these regions.
On the Rhône and the Loire, the snowy episode will give a few centimeters in the first part of the night.
In the west of the Massif Central, an episode of marked freezing rain is expected in the first part of the night. It is the department of Corrèze which is the most exposed, in particular at altitudes above 400 m.
