Lhe rain is everywhere in France. The Ariège, Haute-Garonne and Hautes-Pyrénées are thus moving into flood red vigilance, Météo-France announces in its bulletin at 10:30 p.m. this Sunday, January 9. The departments of Pyrénées-Atlantiques and Landes, already concerned by this alert since the afternoon, remain concerned. The Gave d’Oloron, which flows from the Pyrenees could experience “very significant overflows” from Monday morning, said Vigicrues, the public information service on the risk of floods in France.
Residents of other departments are also called upon to be vigilant. The Pyrénées-Orientales (avalanches), the Gers (floods), Aisne (floods) and the North (floods) are placed in orange vigilance. In all of these areas, road traffic conditions can be made difficult on the entire secondary network and some disturbances can affect rail transport outside the “mainline” network. Power cuts can also occur.
The episode will continue like this until Monday afternoon. Subsequently, the trend will be downward in rainfall intensity, except on the east of the range. The rainy episode should not end until Tuesday during the day. The accumulations of precipitation will become significant over all the Pyrenean departments. On the episode (in 48 hours between Sunday and Monday), we expect accumulations of the order of 40 to 80 mm in the plain, 100 to 130 mm on the foothills of the foothills, 150 to 200 mm in the mountains, locally 250 mm.
