Weather alert: Persistent heat wave and heat wave in the southeast

–

From Sunday, July 24 at 9:00 a.m. to Tuesday, July 26 at 9:00 a.m.

Situation

The heatwave episode and the heat wave in the south-east persist and extend in certain departments until the end of this month of July 2022, which promises to be one of the hottest months ever observed.

This episode is remarkable for its unprecedented duration and intensity, with a record number of days where the maximum temperature does not fall below 35°C. This is particularly the case in the department of Gard.

In this context, the heat wave persists in the south-east, more particularly between the Rhone Valley, Provence and the Languedoc hinterland. The next nights are going to be tropical again. They precede very hot days, with temperatures still between 35 and 40°C.

Evolution

This afternoon, the heat wave and the heat wave continue in the departments placed on orange alert with a maximum of 36 to 39°C in the afternoon, particularly in the lower and middle Rhône valley. On those on yellow alert, the heat will be stronger with an average increase of 3°C compared to yesterday in the direction of Lyonnais. It will thus be 35°C in Lyon against 31°C on Saturday.

Subsequent trend
The heat wave will continue Monday in all of our departments on alert, before the temperatures partially drop in the north of the Rhône-Alpes region in the evening thanks to the lifting of the north wind and the passage of a few showers. Departments, such as the Rhône, will no longer be affected by heat wave alerts. For the south-east, it will be necessary to wait until Tuesday to see the temperatures drop, while remaining at the limit of the heat wave thresholds until the end of the week.
