Short but violent stormy episode Saturday April 18 at night over part of the Gers: the Riscle sector and part of the west of the department. This episode caused a sudden rise in water in the town of Riscle which, as we know, is crossed by three rivers: the Adour, the Boscasse and L’Arrioutor. Plus a canal (Moulin de Tarsaguet canal).
“The three rivers in fact quickly overflowed,” said Mayor Christophe Terrain. “We have 30 to 40 mm of rain in a quarter of an hour around 10:30 pm”
It should be noted that, at the same time, more than 41 mm of water also fell at Troncens. In Riscle, a few businesses, the pharmacy and the bank were affected by floods. ”
