Floods in the Hérault: why rivers stay dangerous after the rain, and how flood insurance claims work

What has been announced

Météo-France's vigilance bulletin of 7 October 2026 (06:01) puts four departments on orange: the Bouches-du-Rhône, Gard and Var for heavy rain with flooding and thunderstorms (pluie-inondation, orages), and the Hérault for river flooding (crues). No department is on red. By the Vigicrues bulletin of 7 October at 09:55, the national maximum for river flooding had already been lowered to yellow (8 sections on yellow).

According to Vigicrues at 04:45 on 7 October, one river section is on orange and seven on yellow. The overnight bulletin marked the upper Orb (Orb amont) as orange; the yellow sections are on the Hérault, Lez, Vidourle, Vistre, Gardon d'Anduze and lower Orb.

We covered what the colours themselves mean yesterday. Today is about something else: why a river alert outlasts the rain, and what to do if water does get into your home.

Rain and river flooding are two different alerts

France runs two services. Météo-France assesses the weather: how much rain will fall, whether there will be storms. The Vigicrues network, run under the ecology ministry, assesses rivers: how high the water will rise on a given stretch. That is why the map on vigilance.meteofrance.fr has separate icons for 'pluie-inondation' and 'crues'.

The morning bulletin of 7 October showed the practical consequence. In the Gard and Var the alert was about rain and storms; in the Hérault it was about rivers. Rain that falls on hillsides takes time to reach the riverbed, so a river can keep rising after the sky has cleared. 'The rain has stopped' does not mean 'the danger is over': check the river levels, not the window.

Vigicrues monitors the main rivers, split into sections (tronçons). Small streams and gullies are not part of that system, and in the south they are the ones that rise fastest. For them there are automatic warnings, Vigicrues Flash and APIC (intense rainfall at commune level), with subscription at apic.meteofrance.fr.

Where to look

• vigilance.meteofrance.fr: the department map, updated at least twice a day, at 6:00 and 16:00.
• vigicrues.gouv.fr: river sections on a map, updated at least at 10:00 and 16:00, with subscriptions to bulletins and warnings for your area.
• FR-Alert: government alerts arrive on phones inside the danger zone automatically, with no sign-up.
• Your department's prefecture website (for example herault.gouv.fr): road closures and decisions on schools and transport.

If water gets into your home: the catastrophe naturelle procedure

Flood damage in France is compensated through a specific procedure: official recognition of a state of natural disaster (état de catastrophe naturelle). The rules, according to service-public.gouv.fr:

1. Insurance. Natural disaster cover is automatically included in property insurance contracts, above all multirisque habitation. Only insured property is compensated. A tenant in France is only required to insure rental risks — fire, explosion, water damage (service-public, fiche F1350 «Assurance du locataire : garanties complémentaires facultatives», checked on 5 December 2025). Their own belongings are covered only if they chose to insure them, so it is worth checking the contract: only what is insured is compensated.
2. Recognition. The town hall files a request with the prefect, generally no later than 24 months after the event. An interministerial order (arrêté) listing the communes is then published in the Journal officiel.
3. Deadline to claim. Damage must be declared to the insurer no later than 30 days after the arrêté is published. The town hall can tell you when it has been.
4. Payment. The insurer pays an advance within 2 months of receiving the damage estimate or of the arrêté's publication, and full compensation within 3 months.
5. Excess. Set by law: €380 for homes and other non-professional property.
6. Temporary housing. Costs of temporary accommodation can be covered if the main residence has become uninhabitable.

The typical mistake is throwing damaged items away before they are assessed. The rules provide that damaged property should be kept and the loss documented with photos, invoices and receipts. Take pictures as soon as it is safe, before cleaning up.
