Avalanche warning for region Tromsø Monday 07.05.2018

Danger level 2 - Moderate avalanche danger

Published:
The snowpack is still wet and unstable in lower areas. Avoid potential release areas and runout areas for avalanches. It might be some spots with fresh wind deposited snow at high altitude.

Avalanche problems

Wet 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).

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

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)

Sunday 6. May 2018

Snøoverflaten er fuktig. Det var fravær av nattefrost natt til lørdag og søndag, dette gjør at varmen trekker ned i snødekket. Snøgrensen ligger på ca.150 moh.

Det finnes vedvarende svake lag av kantkorn og begerkrystaller i deler av regionen etter kuldeperioden tidligere i vinter. Stedvis ligger det mye og delvis hardpakket snø over lagene i høyden og i nordvendte sider, mens mildvær har stabilisert de svake lagene i lavere høyder.

Det har gått flere våte løssnøskred de siste dagene.

Mountain weather

Sunday 6. May 2018

5-8 mm precipitation. Fresh breeze from south, changing to moderate gale from the southwest Sunday night. -2 °C to 3 °C at 700 m a.s.l. Cloudy.

Monday 7. May 2018

5-9 mm precipitation. Strong breeze from southeast, changing to moderate gale from the west during the afternoon. -2 °C to 1 °C at 700 m a.s.l. Cloudy.

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

Kaldere vær og nattefrost gjør at faren for våte skred synker, men den vil fortsatt være gjeldende der det er plussgrader. Det kan komme noe nysnø i høyden i kombinasjon med mye vind. Dette vil gi ferske fokksnøflak, hovedsak i NV-vendte lesider over 700 moh, men kan dreie mot kvelden og gi flakdannelser også i mer NØ-vendte lesider.
