Avalanche forecast for Sør-Troms Saturday 2019-01-19

2
Moderate
Published:

Snow showers from NW may cause storm slabs to form. These can mix with the widespread surface hoar layer that where observed on Wednesday. There is a great deal of uncertainty in the forecast.

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.

Ingen faretegn observert under 650 MOH (tregrensa). Endring i snøen (mer vindpåvirkning) over tregransen. Vestvendt heng over skoggrensa tynnere snødekke, og sukkersnø under der snødekket er tynt. Generelt veldig god skikjøring.
