Mild weather and rain will lead to a number of naturally triggered wet avalanches in steep slopes in all aspects.

At higher elevations, fresh wind-drifted snow will be very easy to trigger in northeast-facing slopes. Some naturally triggered avalanches may also occur.

The northwestern part of the region is expected to receive the most precipitation, and this is where the avalanche danger is expected to increase the most.

The older faceted weak layer is either stabilized or buried deep beneath a hard crust and supportive snow up to about 1300 meters above sea level. Above this elevation, faceted snow within the snowpack may be affected in some areas—for example, in transitions between thin and thick snow cover. Smaller avalanches in wind-drifted snow can cause deeper faceted layers in the snowpack to collapse. Avalanches resulting from such collapses can become large.

Mildvær og regn fører til at det vil gå en del naturlig utløste våte skred i bratte heng i alle himmelretninger. I høyfjellet vil fersk fokksnø være svært lett å løse ut i nordøst-vendte heng.

Utover kvelden synker temperaturen og det ventes snøbyger lavere i terrenget. Myke flak som dannes der vinden flytter snø vil være lette å påvirke, men skredstørrelsen ventes å være begrenset til små eller middels store.

Det er nordvest i regionen det er ventet mest nedbør, og det er derfor der skredfaren ventes å øke mest.

Det eldre kantkornlaget er enten nøytralisert eller ligger dypt under hard skare og bærende snø opp til ca. 1300 moh. Over denne høyde kan kantkorn i snødekket påvirkes enkelte steder. Eksempelvis i overganger mellom tynt og tykt snødekke. Mindre skred i fokksnø kan føre til at kantkorn dypere i snødekket kollapser. Skred som følge av kollaps i kantkornlag kan bli store.

Mandag var det kommet rundt 10 cm nysnø med vind fra vestlig retning. Snøen var fuktig opp til ca. 1000 moh. Vindtransportert snø med ulik fasthet finnes hovedsakelig i øst- og nordvendt terreng. Vindutsatt terreng har generelt lite snø, og stedvis avblåst ned til skaren. Snøgrensa varierer med himmelretning, fra 400 og helt opp til 900 meter. Mildvær i midten av mars har trolig nøytralisert gamle vedvarende svake lag av kantkorn under ca. 1300 moh. Over denne høyden kan gamle vedvarende svake lag muligens påvirkes med stor tilleggsbelastning eller på tynt snødekke.

The transition to calm and fair weather is causing the avalanche danger to decrease, but locally unstable conditions will persist. Wind-drifted snow slabs at higher elevations from Wednesday and overnight into Thursday are expected to stabilize but may still be easily triggered in certain areas.

In south-facing slopes, where the sun has a strong impact during midday, a few small, naturally triggered wet loose snow avalanches are expected.

Maintain a safe distance from cornices in the high mountains, as these become unstable with rising temperatures or additional snow loading.

The older faceted snow layer is either neutralized or lies deeply beneath a hard crust and supporting snow up to approximately 1300 meters above sea level. Above this elevation, faceted snow layers in the snowpack may be triggered in certain areas, such as transitions between thin and thick snow cover. Smaller avalanches in wind-drifted snow can cause the deeper faceted layers in the snowpack to collapse. Avalanches resulting from col
