On the Hérault and the Gard, “this Tuesday, the situation becomes favorable for intense thunderstorm developments with little mobile or even stationary thunderstorms. For this reason, there is a significant risk of very heavy accumulations of rain in a short time, typically of the order of 80 mm in less than 3 hours. During the day, cumulations close to 100 to 150 mm are therefore expected locally. Hail and gusts of wind may also accompany these storms.says the meteorological agency.
“At this stage of the forecast, there remains a marked uncertainty both in chronology and in the precise locations of these storms. However, the most intense activity seems to be at midday and this afternoon. This situation calls for a special attention, especially as this episode could continue during the day of Wednesday“.
“From the Massif Central to the North-East, this afternoon and this evening, thunderstorms will again develop from the Massif Central then these will quickly rise in the south-westerly flow towards the north of Rhône-Alpes, Burgundy and Franche-Comté These storms will generally be quite brief but sometimes violent with sustained gusts of wind (close to 100 km/h), hail and very strong precipitation intensities locally giving quite significant accumulations. The improvement will come quickly at the back of this new stormy wave and will generalize in the night”.
