Météo France refers to an “exceptional event”. Five departments of the Southwest were placed this Saturday afternoon in orange rain flood alert by the meteorological institute. These are Gers, Gironde, Landes, Pyrénées-Atlantiques and Hautes-Pyrénées .
"It is the duration of the sustained rains as well as their fairly wide geographic area that make this event exceptional," explains Météo France. The quantities forecast in 48 hours could thus be close to the centennial values. "
“It is difficult to identify successive waves but between Sunday afternoon and Monday noon, the periods of heavy precipitation are linked together, giving significant, sometimes even exceptional, accumulations. Their sequence is the dominant stake, the stormy character being drowned in the mass ", underlines the institute, which waits" on the whole of the episode, 50 to 100 mm almost generalized on the departments placed in orange vigilance " .
