Description
The FOEN also issues information when a sharp rise in small and medium-sized river levels is expected locally. In these cases, it is impossible to say precisely which rivers will be affected, particularly in heavy thunderstorm precipitation. To give an indication, the regions affected will be marked on the Flood Alert map in small catchments. Only two hazard levels are available for small and medium-sized rivers in advance of an event: no or low risk (green), and likelihood of flooding (intensity undefined, yellow). If a very large flood is in progress, the danger level red is used. It is issued on the basis of measurement data and not in advance
