Meteorologists can generally predict sustained heavy rainfall a few days in advance. During this period, you should keep abreast of the current weather developments, and gather information on the potential hazards associated with heavy rainfall (high water, flooding, landslides etc.).
Advice on what to do in preparation for a heavy downpour or continuous heavy rain:
- Keep an eye on local weather developments, and act appropriately, according to the information you receive on the conditions.
- Heed the push notifications on the MeteoSwiss App.
- Place objects up high in areas or rooms that are at risk of flooding.
