Avalanche forecast for Tromsø Friday 2019-01-18

2
Moderate
Published:

Some smaller storm slabs might have formed on Wednesday and could be easy to trigger. The recently formed wind slabs has gained strength and are proving hard to trigger. The old persistent weak layer near the ground is locked by strong overlaying snow.

New snow (slab avalanches)

Buried weak layer of new snow

Be careful in steep slopes and around terrain traps until the new snow has stabilized. The avalanche problem is generally widely distributed on any steep slope with deep new snow. Look for cohesive new snow that breaks apart or is poorly bonded to the old snow. Cracks around your skis are a typical dangersign.
