France is set to experience another burst of warm weather towards the end of this week, with temperatures across the entire country hovering significantly above September averages.
A warm flow of air rising north from the Mediterranean sea is the reason for the rise, say forecasters.
The temperatures will rise after the stormse currently sweeping through most of France depart.
There are 83 departments facing tier-two storm warnings throughout the course of Tuesday (September 12), with some warnings continuing into Wednesday.
From Wednesday, overnight temperatures could be as high as 18C in most of the country, with highs during the day of 28C.
Towards the weekend, however, these may increase to 19C and 30C respectively.
It is unlikely though that any further official heatwave (canicule) warnings will be declared even if the temperatures are higher than average.
Storms will need to pass first
Tuesday’s storms will have to pass before temperatures can climb again.
The current set of storms sweeping across France have dropped temperatures by around 5C from where they were at the start of the week – although they will still be above seasonal averages for September.
As the storms move eastwards throughout the day a number of departments will face tier-two warnings, with 83 departments overall facing storm warnings at some point.
You can see a full list of departments facing warnings on the official Météo France website.
If you click on the ‘orages’ tab on the right hand side and then the play button underneath the map, a video of the map will play showing how the warnings will change throughout the day.
Wednesday will see some warnings remain in place – largely in the east – before the storm moves further across Europe by the end of the day.
End of storms bring more heat
When the storms end temperatures will increase again by 3C or 4C above seasonal averages.
It means temperatures of up to 30C could be recorded – most likely in the south but possibly in the north – and almost all of France will see temperatures at 20C or higher.
Most places will see maximum daytime temperatures between 26C and 29C during the weekend.
Night-time temperatures are expected to be around 15C and 19C until Sunday.
Next week will start with more storms which are set to bring the temperatures back down to seasonal averages, after which they are unlikely to rise significantly again.
Forecasters predict that this could be the third-hottest September ever recorded in France.
