Hot weather is expected this weekend of September 10 and 11, in the south of France and more particularly in the southwest. The peak of high heat is forecast for this Sunday, or even this Monday. Temperatures, very high for the season, could be around 39°C in Occitania this Sunday and, at the foot of the Pyrenees, thermometers could climb to 36°C. \ud83c\udf21?

This weekend, as it approaches the Portuguese and Spanish coasts, storm Danielle will turn into a cold drop and, in a way, “push” a mass of warm and very hot air from North Africa towards our latitudes. The wind will turn south to south-east, causing temperatures to rise in south-west France as well as in the Atlantic arc. This phenomenon forms what is called a “heat pump”.

If the heat peak is expected for this Monday, September 12, the phenomenon could continue until Tuesday, say some experts. According to Météofrance, this Tuesday, September 13, a stormy deterioration is expected over all of western France. It could even break out on Monday evening in Spain and in the Pyrenees. Another consequence of this heat peak: the mass of hot air from North Africa should favor the appearance of a cloud of desert and sandy dust over France and cause the return of sand rains when the storms break out. .
