Gale-force winds, heavy snowfall, freezing rain, heavy precipitation and thunderstorms cause considerable damage to nature and infrastructure, as well as endangering people. Timely, accurate and clear warnings are essential for limiting the consequences of extreme natural events. The experts at MeteoSwiss are the first to identify whether a storm is imminent that could put people in danger and cause damage. If the forecasts for precipitation, wind strength or other variables reach certain threshold values, warnings are issued to the authorities and the public.

Warnings on the hazard map and in the MeteoSwiss app

On the hazard map, MeteoSwiss provides information about current meteorological hazards such as wind, thunderstorms, rain, snow, icy roads, heat and frost. The map also displays warnings of other natural hazards such as floods, forest fires and avalanches. It is updated continuously.
In the MeteoSwiss app, the user can subscribe to push notifications for warnings for any location, type of hazard or warning level.
