Avalanche forecast for Tromsø Thursday 2019-01-24

3
Considerable
Published:

Use great caution in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. The danger is highest during the afternoon and evening due to a wind increase.

Wind drifted snow (slab avalanches)

Poor bonding between layers in wind deposited snow

Avoid steep (more than 30 degrees) areas with fresh wind deposited snow, especially convex terrain. An avalanche is easier to trigger where wind slabs are thin or soft. Look for areas where the wind recently has deposited snow, typically behind ridges, ribs and in gullies. Remember that local wind effects will cause variation in where the wind slabs occur.
3 - Large
Low additional load
Some steep slopes

Notes

Mye snø som transporteres og sterk vind. På vei ned ved stopp i en sving kom det en skytende sprekk på cirka 10 meter. Rask forandring i forholdene i og med den sterke vinden og snø tilgjengelig for transport.

Other dangersign (specify)

2-3 små skred,strl.1 mest sannsynlig gått tirsdag

Notes

Tur til Buren via "normalruta". Hadde ventet at snøoverflaten skulle vært mer påvirket av vindøkningen tirsdag. Det generell inntrykk var at det var dannet tynne myke fokksnøflak, mens på mer vindutsatte områder var flakene hardere. Vi observerte det lille skredet som var omtalt på FB tirsdag og i media. Dette hadde blitt kontrollert utløst i lite heng mot sør der det var innblåst mye snø. Testhopp idag på samme sted ga ingen oppsprekking. Vi opplevde heller ingen oppsprekking andre steder. Kjapptester med hånda flere steder underveis indikerte god stabilitet i fokksnøen. To små naturlig utløste skred i lite heng mot sør ble observert; gikk mest sannsynlig tirsdag de også. Så oppsummert opplevde vi mye fin skikjøring idag også. Men man bør nok fortsatt være obs i bratte heng der det er blåst inn mye fokksnø.
