Avalanche warning for region Sør-Troms Wednesday 29.01.2020

Danger level 2 - Moderate avalanche danger

Published:
Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Especially where the wind slabs are thin or soft, an avalanche is easier to trigger.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Below you can see a description of the current snow cover information and current weather forecast in the mountains. If your observations deviate greatly from what is described here, the warning will not necessarily apply either. Always make your own judgments or stay away from avalanche terrain.

Snow cover (in Norwegian)

Tuesday 28. January 2020

Kraftig vind søndag og mandag har transportert løs snø fra helgen over i leområder. Her vil det ligge fokksnøflak av varierende hardhet. Utsatte steder er det avblåst ned til gammel skare.

Under tregrensen er snøen stedvis ubunden.

I forrige uke ble det observert kantkornlag og begerkrystaller lenger ned i snødekket på fastlandet.

På søndag ble det observert noen naturlig utløste flakskred i bratte heng på Grytøya.

Mountain weather

Tuesday 28. January 2020

No precipitation. Strong breeze from southeast. -15 °C to -8 °C at 700 m a.s.l. Partly cloudy.

Wednesday 29. January 2020

No precipitation. Fresh breeze from southeast. -13 °C to -6 °C at 700 m a.s.l. Clear skies.

Advice

The bulletin is a planning tool and may differ from the actual situation. Always make your own evaluation. To be 100 % avalanche safe, avoid all avalanche terrain.

Avalanche risk assessment

Vinden roer seg og fokksnøen fra de tre siste dagene stabiliseres gradvis. I høyden går stabiliseringen tregere fordi det er kaldt, og det kan fortsatt være lett å løse ut skred enkelte steder.

Forholdene med kalde temperaturer ligger til rette for ytterligere utvikling av kantkorn nær bakken, og man bør ha dette i bakhodet, særlig der snødekket er tynt.
