Validity: from 10.12. 20:00 to 13.12. 12:00
- Possible impacts: Rising water level of streams and normally dry ditches. Localised flooding, e.g. in underpasses, underground garages and cellars. Landslides on steep slopes
- Recommendations for action: Stay away from watercourses, lake shore areas and steep slopes. Pay attention to possible flood warnings from the FOEN. Keep out of cellars and basements when there is a danger of flooding (see procedures for flooding). Avoid watercourses in the mountains 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
