- Possible impacts: Significant and rapid rise in the water level of rivers and lakes, flooding. 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. 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.
