LIVE – Five departments remain this Monday morning in red vigilance for flood and / or rain-flood phenomena – Here is the new alert map

07h18: This morning, Météo-France noted a remarkable episode of very heavy precipitation in progress on the mountain range, and a high risk of avalanches. Without forgetting a risk of significant floods on the Pyrenean rivers and very important on the Gave d’Oloron, downstream of the massif. In all, five departments remain on red alert for flooding and / or rain-flooding phenomena. After the passage of the Pyrénées-Atlantiques and the Landes in red for flood risks, Météo-France placed the Hautes-Pyrénées, Haute-Garonne, Ariège and Pyrénées-Atlantiques on Sunday evening in maximum rain vigilance.flood.

We will keep a moderate activity, sometimes quite strong (rainfall intensity between 5 and 10 mm / h), and a rain-snow limit above 2000m at the end of the night and Monday morning. These rains will therefore locally generate overflows of watercourses, or even landslides or mudslides. The rainfall intensities will gradually weaken in the afternoon, justifying the end of red vigilance and a return to orange vigilance, to be refined however during the day.

The rain-snow limit will decrease from the beginning of the afternoon on the east of Ariège, and later at the end of the day and evening on the west. In the evening, it becomes between 1200m on the Ariège and 1600 / 1700m on the Western Pyrenees, with less precipitating activity. This rainy episode will end at the end of the night of Tuesday in the east and later in the morning of Tuesday more in the west.

The accumulations of precipitation will become significant over all the Pyrenean departments. On the episode (in about 48 hours between Sunday and Monday), we expect accumulations of the order of:

– 50 to 80 mm in the plain

-100 to 130 mm on the first foothills, valleys and foothills.

-150 to 250 mm in the mountains.

It should be noted that the melting of the snowpack present below 2000/2200 m will help to reinforce these accumulations.
