Raw vigilance — VIC

Raw vigilance is developed by the Ministry of Ecological and Solidarity Transition. It is established by the Central Hydro — Meteorology and Support Service for Flood Forecasting (SCHAPI) attached to the Department’s Risk Prevention Directorate in collaboration with the 19 flood forecasting services (SPCs attached to DREAL or Météo-France). Its aim is to raise awareness of the flood risk by informing the general public and crisis management actors with the same message of the level of flood risk occurring on the main rivers monitored by the State. The public authorities in charge of civil security (prefects and mayors) receive this alert when necessary and mobilise the appropriate means of relief. France and overseas are divided into territories with raw competence (TCC) — each is managed by a flood forecasting service (SPC) or a hydrometeorological watch cell (HCV) and the Central Hydrometeorology and Flood Prediction Support Service (SCHAPI). The management of a TCC is therefore carried out by a government department or a public institution. The regulatory framework for a TCC can be defined by regulatory instruments. In the specific case of SSCs, these include: the regulations for monitoring, forecasting and transmitting flood information (CIR). the Master Plan for Flood Forecasting (SDPC) (see Circular of 04 November 2010 NOR: DEVP1023695C). Within each CBT, there are raw vigilance entities. A raw vigilance entity may be: — a specific location on a watercourse located at a hydrometric station or meteorological site, — a section of raw vigilance (i.e. thematic hydrographic segment), — a catchment area (i.e. watershed), — an area or territory of raw vigilance encompassing several raw vigilance entities, on which a summary of the information of raw vigilance can be made. Each watercourse, integrated into the raw vigilance and visible on the vigilance map, is divided into sections (i.e., raw vigilance entity). Each section is affected by a colour: green, yellow, orange or red depending on the level of vigilance required to deal with flood hazards that may occur within 24 hours.
