White frost this Friday: the 30 departments that will be affected

After a very unstable week, marked by thunderstorms that caused significant damage in the south of France, particularly in the Var region, France is preparing to experience morning frosts this Friday and Saturday morning.

"Conditions favorable to the formation of white frost"

According to La Chaine Météo , the sky is expected to clear overnight from Thursday to Friday. "Combined with polar cold, this will create favorable conditions for the formation of white frost, particularly in sheltered rural areas," the specialist website indicates. Locally, it could get as cold as -2 degrees. Orchards and vineyards could be particularly vulnerable, as could some of your plants.

Should you bring your potted plants indoors?

Even if the frost will be light and short-lived, it may be useful to protect your plants in the affected departments (list at the end of the article). According to My Bleen (a company specializing in ecological garden products), many plants are "particularly sensitive to frost and nighttime temperatures below 5 degrees." This is the case for zucchini, tomatoes, and peppers. As a precaution, you can install a wintering fleece around the most sensitive plants and fruits and vegetables in your garden . As these frosts are very short-lived, the risk of seeing your plants die remains low. You can also bring your potted flowers indoors until Saturday, when possible.

A morning freshness that will quickly fade

While Friday and Saturday mornings are expected to be cool, temperatures will rise rapidly once the sun rises. This Friday afternoon, for example, temperatures are expected to reach 12°C in Paris and Brest, 16°C in Lille and Troyes, and 19°C in Auvergne-Rhône-Alpes. By the end of the week, the risk of morning frost should diminish, thanks to increased cloud cover, allowing for milder nights.

This Saturday, May 24, the weather will be generally pleasant, with a veil of clouds sometimes thick over a large part of France. Some rain will be possible in the Hauts-de-France, in the Alpes-Maritimes and Hautes-Alpes mountain ranges, as well as in the Corsican mountains . The sky will be perfectly clear around the Mediterranean. Sunday, the sky will be more mixed. A disturbance coming from the west and bringing rain is expected to affect the Hauts-de-France, Brittany, Normandy, Île-de-France, Pays de la Loire and part of the central Val-de-Loire. In the rest of the country, cloudy skies. Some rain will also be possible in the mountain ranges of Corsica, Ariège and the Hautes-Alpes.
