- Possible impacts: Significant and rapid rise in the water level of rivers and lakes, flooding. Landslides on steep slopes. Flooding of underpasses, underground garages and cellars/basements. - 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. Avoid flooded stretches of road and drive around. - Expected amounts: 200-260 mm - Snowfall limit: 3800 - 3400 m (sinking) - Peak phase of the event: Thu 06 - Thu 18 - Intensifying conditions: locally higher precipitation amounts due to embedded thunderstorms
