“A change in weather is looming” from this Monday, November 18, warns Météo-France. Heavy rainfall is expected on the Channel coasts, while the east is expected to see snowfall. At the end of the week, the country should experience a slight cooling.
We take stock of the weather for the week.
Sustained rains and drop in temperatures
The Channel coasts, in Normandy and Hauts-de-France, were affected on Monday by a disturbance from the British Isles at the start of the week. “The accumulations could locally reach 50 to 80 mm in the space of 24 hours, corresponding to 3 weeks of rain in the month of November,” reports La Chaîne Météo.
From the Pays de Caux to the Somme estuary, several sectors will be affected by the risk of flooding. These heavy rains will continue overnight from Monday to Tuesday.
More generally, “temperatures will continue to drop during the week and will take on a more wintry character”, forecasts Météo-France. However, it is not a cold snap, as clarified by La Chaîne Météo, which writes that “Temperatures will be on average 3°C lower than seasonal norms”.
Snow in eastern France
With this drop in temperatures, snow is expected to appear on Tuesday. She goes “falling in abundance in the second part of the day on all the eastern reliefs”, according to La Chaîne Météo, and “at lower and lower altitudes at the end of the day”.
“We expect up to 50 cm of snow by Friday,” can we read on the X account of La Chaîne Météo.
It will continue to snow on Wednesday in the Alps, with strong gusts of wind in the Mediterranean and Corsica. “Thursday will be the highest risk day of the week,” warns La Chaîne Météo, which evokes a “strong gust of wind possible” between the southwest of the country and the northern Alps.
After the passage of this depression, the “situation could finally calm down”, although it is possible that “snow showers reach the level of the plain between Lorraine, Alsace and Rhône-Alpes”.
Warm weather next weekend
Temperatures are expected to rise for the weekend of November 23 and 24. According to the Météo-France website, temperatures on Sunday afternoon will be between 10°C in Alençon or Rennes and 21°C in Biarritz or Ajaccio.
But Saturday will be ” humid “ warns The Weather Channel: “Going up to the north and west, the wind will blow strongly with rain. »
Sunday the weather will be “rough, frequently rainy and windy” in the north and west, while cloudy skies are expected in the rest of the country.
