The equivalent of a month of rain

It will be necessary to be careful during these next hours in Calvados (14) and in the Orne (61). These two departments are under surveillance. A particularly rainy disturbance is expected for the next night warns Agate Weather.

Due to its continuous and intense precipitation, this disturbance could lead to overflows of watercourses and thus cause localized flooding. The expected accumulations could be of the order of 50 to 70 mm, or 80 mm punctually. As a reminder, the average monthly rainfall for October is 78 mm in Caen (Calvados) and 76 mm in Alençon (Orne). In addition, it is not impossible that the downpours that fall will take locally a stormy character
