The flood warning remains yellow on the lower Hérault, in the department of Hérault, in Occitanie, this Thursday, October 1, 2026. In its bulletin updated at 5:55 a.m., Vigicrues reports that the flood wave is moving downstream and causing localized overflows in the plains near Montagnac.
What is observed
The floodwaters are spreading from upstream to downstream along the Hérault River. Vigicrues reports localized flooding, described as non-damaging in its bulletin, in the plains near Montagnac. This is an observed situation, not a forecast of widespread flooding.
The rain event is now mainly affecting the Gard department and the Provence-Alpes-Côte d’Azur region. For the Hérault department, the weather report specifies that the deterioration is only marginally impacting the department this Thursday morning and that any remaining rainfall should be less significant. However, this does not mean that the risk of flooding downstream of the Hérault River has disappeared.
The areas concerned
The alert concerns the lower Hérault section, within the Western Mediterranean alert zone. Vigicrues monitoring focuses particularly on the stations of Aspiran, Montagnac, and Agde. The bulletin locates the observed flooding in the plains near Montagnac; it does not specify that it affects all the municipalities along the stretch of river.
