Avalanche forecast for Romsdal Saturday 2019-02-09

2
Moderate
Published:

There is a persistent weak layer buried in the snow pack, especially at tree line. Be careful in areas with wind deposited snow.

Persistent weak layer (slab avalanches)

Buried weak layer of faceted snow near surface

Keep distance to each other when traveling in avelanche terrain. NB, remote triggering is possible. Make very conservative route choices, especially in unknown terrain, after snowfall and if temperatures rise. Identifying areas where the weak layer is present might be difficult and requires experience. Danger signs are whoumpf-sounds and cracking which means that you influence weak layers and should avoid avalanche terrain. However, absence of signs does not mean it is safe.
2 - Medium
Low additional load
Isolated steep slopes
Possible

Danger Sign

Recent snowdrift Det var sørlig lett bris og stadig lett vindtransport.

Avalanche Problems

Dry slab avalanche Buried weak layer of faceted snow above a crust Within half a meter The collapsing weak layer is thin < 3 cm. The overlying slab is soft. Difficult to trigger 1 - Small N, NE, E, SE, S, SW, W, NW above 800 masl Vi gravde ved 800 moh. Antar at kantkorn ligger helt opp til toppene pga dannelsen under kalde, klare netter. Usikker ang nedre grense

Danger Sign

No signs observed Ingen markante faretegn der jeg gikk i dag.

Avalanche Problems

Dry slab avalanche Buried weak layer of faceted snow near surface Within half a meter A big and identifiable crystal in the weak layer. Difficult to trigger 2 - Medium N, NE, E, W, NW above 700 masl Kunne også vært få bratte heng.

Avalanche Danger Assessment

2 Moderate Det var en lun dag til fjells i dag, men ganske flatt lys. Ble mildt med plussgrader i skogen i ettermiddag. En del vind helt øverst men lite snø å flytte på. Snøen gir lite faretegn men lett å finne kantkorn under den stive fokksnøen. Har ikke funnet rimkrystaller av betydning. Nesten inntrykk av Fg 1 der jeg gikk i dag , men gir en toer for regionen som helhet. Stiger ved neste større snøfall men litt usikker på om det er nok snø tilgjengelig hvis bare vind , men kanskje får den flytte en del hvis veldig kraftig vind. Kanskje få fram at det er store forskjeller i regionen ? Ytre, indre etc.

Snow Cover

120 cm in total Some snow drift 1 cm new snow Elevation of new snow 0 masl. Snow line at 0 masl. Layered snow begins at 700 masl Some loose snow (1-10cm) Dry Ligger noen få cm ganske ny snø på overflate. Ikke 10-15 cm nysnø her i Isfjorden, kanskje i ytre deler av regionen. Under den lille nysnøen er det over tregrensa stort sett vindpakket hardt (1F eller hardare) eller vindpakket mykt 4F . Eller løsere kantkorn vaffelsnø .

Tests

@15cmQ2 Good Svikter med middels tilleggslast under fokksnøen i løs kantkorn.

Avalanche Activity

7. Feb. During the day (+01:00) No avalanche activity Ingen dagsferske skred å se.

Snow Profile

5 stratigraphy layers observed Bare de øverste lagene . Over 1 m snø her egentlig . Mindre kornstørrelse på kantkorna her enn der tynn snødekke .
