Rainstorm in the Southern France

An inflow of moist air from the Mediterranean Sea resulted in a line of heavy thunderstorms that trained across the southern French districts of Gard and Herault for almost 36 hours September 16-18. The mountainous terrain of the region contributed to orographic enhancement of the rainfall and some astonishing rainfall amounts were measured. A possible new all-time 2-hour rainfall record for France of 180 mm (7.09”) was measured at Saint-Gervais-sur-Mare (Herault District) between 10 p.m. and midnight on September 16th, surpassing the previous record rainfall for a two-hour period of 178.4 mm (7.02”) at Solenzara on October 26, 1979.
