Description

Landslides may be expected. Exposed railways and roads may be closed. Heavy rain is expected. Relatively high temperatures and windy conditions causes significant snowmelting. The expected rain will increase the danger of landslides, especially where groundwater and soil moisture are already high. Risk of slushflows is especially high in areas with more than 50 cm snow. Slushflows are triggered even in relatively gentle slopes, where water accumulates. Slushflows follow terrain depressions and may develop into debris flows.
