The Vigicrues application is intended to inform the public of a potential danger linked to floods on the main rivers in France, monitored by the State. This danger is materialized by a color of raw vigilance to which bulletins and forecasts are associated.

This application, managed by the State services, is free and provides the following information:
- raw alertness level (green/yellow/orange/red);
- national and local information bulletins written by flood forecasters, and behavior advice adapted to the situation;
- water levels and/or flows observed in watercourses
- forecasts of water levels and/or flows at certain stations, in a flood situation;
- maps of flood zones in certain sectors.

The application makes it possible to geolocate on the map and to visualize the sections of rivers and the stations nearby.
The application also allows you to create a personal account to benefit from personalized subscriptions and warnings.
Subscriptions allow you to receive a notification each time a newsletter is published.
Warnings allow you to receive notifications when there is a change in the color of flood vigilance on a section of watercourse, a territory, or a department; and to receive notifications when the level of the stream exceeds the threshold chosen by the user on a station.
