Slush slides warning yellow level for deler av Trøndelag og Nordland

2

Yellow level

Published: Valid: from 24.03.2020 07:00 to 25.03.2020 06:59
Next forecast before:
  • Danger decrease: Wednesday afternoon 25. Mar. 2020
  • Height: 0 - 700 moh

Consequence

Some landslides are expected. A few large events may occur. Exposed railways and roads may be closed. Slush slides: A flow of waterlogged snow. These landslides can start in relatively flat terrain and seek towards streams and steep slopes.

Advice

Keep yourself updated about the development of the weather, the landslide and flood situation, and follow the weather radar. Keep water paths and culverts free of snow, ice, gravel, waste, twigs and leaves. Clogged waterways with dammed water may cause landslides.

Description

Risk of slush flows is especially high in areas with more than 40 cm snow. The snow may in some places be fully water-saturated. Slush flows are triggered even in relatively gentle slopes, where water accumulates. Slush flows follow terrain depressions and may develop into debris flows.
