These storms will follow a particularly hot day.
The most intense phenomena are announced in the evening, from 20h.
In addition to intense electrical activity, these storms could cause violent gusts of wind, hail and heavy accumulations of rain in a short period of time.
From this afternoon, isolated storms could break out in Alsace, with possible gusts between 40 and 60 km/h.
A deterioration is expected around 8 p.m. with particularly violent storms. They could be accompanied by:
– violent gusts of wind (80 to 100 km/h, up to 120 km/h locally),
