“The remarkable stormy deterioration is moving from the southwest to the northeast of the country,” notes Météo-France.
“In the Grand Est, the storms will be particularly virulent, with the possibility of accumulations of rain of 50 to 80 mm in a short period of time, very strong gusts of wind (between 100 and 120 km/h at times) and large hail (diameter which could reach or exceed 5 cm in places), as well as intense electrical activity,” warns the weather forecast service.
“The stormy deterioration has well established itself from the southwest of the country to the Massif Central and towards the Grand Est,” indicates Météo-France. “Diluvian storms impacted the Tarn department where we recorded 61 mm in one hour in Dourgne, 56 mm in one hour in Montredon and 66.6 mm in three hours in the same place,” continues Météo-France.
In its previous bulletin, it indicated that storms with rainfall intensities of around 20 to 30 mm/h had been observed in the Lot department at the start of the afternoon.
A “strong rainy-stormy episode” crosses “most of the country” on Saturday, Météo-France indicated. “Only the regions from Brittany to Nord-Pas-de-Calais, as well as Corsica, remain away from these bad weather, and maintain calmer but cloudy weather.”
For the departments concerned by this vigilance, the meteorological service warns of a “strong summer stormy situation which requires particular vigilance given the geographical extent and intensity of the predicted phenomena”.
“In addition to intense electrical activity, these storms can cause violent gusts of wind, hail and heavy accumulations of rain in a short time,” warns Météo-France.
In Lorraine, where several festive events were cancelled, the Olympic flame route was able to take place in the Meuse. However, the last relay passes had to be brought forward to avoid the storms.
In Strasbourg, ahead of the possible arrival of storms, the city hall announced in a press release the closure from 5:00 p.m. of six municipal parks and the city’s nine cemeteries. “Their reopening will depend on the evolution of weather conditions.”
In Doubs, the Rencontres et Racines music festival, which is being held from Friday to Sunday in Audincourt, announced on its Facebook page that it would not take “the risk of opening the festival” on Saturday due to the weather conditions.
According to Météo-France, “in Aquitaine, frequent storms were observed” on Saturday, with “strong electrical activity, locally strong rain intensities”.
On Sunday, the situation in the North-East will be “strongly stormy” and will require “particular vigilance given the geographical extent and the intensity of the forecast phenomena”, forecasts Météo-France, according to which, “in addition to intense electrical activity, these storms can cause violent gusts of wind, hail and heavy accumulations of rain in a short time.
