Recommendations during rain

General recommendations before rain

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.

General recommendations during rain

Intensive downpours cause streams and rivers to fill up very rapidly, and can quickly lead to regional flooding as well as set off landslides in areas with steeply sloping terrain. Care should therefore always be taken when outdoors in heavy rainfall, particularly in the vicinity of water and sloping terrain, but also when driving on the roads.

Advice on what to do during heavy rainfall:

  • 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<<;
  • Stay away from water (as well as dry river or stream beds) and from shores and river banks;
  • Keep out of cellars and basements when there is a present danger of flooding, and place objects up high (see procedures for flooding);
  • Avoid steeply sloping terrain;
  • Avoid steep watercourses in the Alps at all cost, as these are prone to mudslides. A mudslide can occur very suddenly and without warning, and can be a powerful destructive force;
  • Avoid bridges where there is flooding;
  • Avoid flooded stretches of road and drive around them;
  • If possible, stay at home;
  • Always follow the official recommendations.

General recommendations after rain

Even after the rain has abated or stopped, streams and rivers will still be very high . You should therefore continue to take extra care until the flood risk has passed.

Advice on what to do after a heavy downpour or continuous heavy rainfall:

  • Keep an eye on local weather developments, and act appropriately, according to the information you receive on the conditions;
  • Stay away from water (as well as dry river or stream beds) and from shores and river banks;
  • Avoid steeply sloping terrain;
  • Mudslides are still a possibility along steep watercourses in the Alps, and these areas should be avoided until the high water has abated.
  • Avoid bridges where there is flooding.
