Danger Sign

No signs observed

Weather

No precipitation 1.6 °C 6 m/s from W → 100% clouds Overskyet og en del vind. Såvidt nattefrost på Sinnes i natt.

Snow Cover

75 cm in total No snowdrift Snow line at 650 masl Wet loose snow Wet Sammenhengende skiføre fra 650m i Hunnedalen nå. Grovkornet til smelt frys dekke til topps. Temmelig råttent og sugete lavt nede utover dagen uavhengig av himmelretning. Mest snø i nordøstlig himmelretning grunnet lite sol og at vest sørvest har vært mest fremherskende gjennom vinteren.

Avalanche Danger Assessment

1 Low Generelt stabile forhold. Gjelder å følge med på nattetemperatur og starte tidlig for å få kurant skiføre i denne delen av regionen nå. Glideskred kan forekomme Nedbør utover helga vil drenere godt i denne snøen og eventuell nysnø er fuktig og legger seg på gunstig vis mot varm snø. Forecast correct

Avalanche Problems

Wet slab avalanche Wet snow/melting near the ground Over one meter Spontaneous release 2 - Medium N, NE, E, SE, S, SW, W, NW below 1000 masl Setter grensen på 1000 meter selv om det trolig er mye høyere fordi det er det jeg har oversikt over i nå.

Avalanche Activity

8. May. During the day No avalanche activity

Danger Sign

No signs observed

Weather

No precipitation 0.5 °C 10 m/s from NW ↘ 100% clouds Overskyet, stort sett opphold med noen byger av yr. Ingen nattefrost i Hunnedalen. Tåke i høyden.

Snow Cover

75 cm in total No snowdrift Snow line at 600 masl. Layered snow begins at 1000 masl Wet loose snow Moist Skiføret kryper stadig oppover, men det er fortsatt mulig å ferdes på ski i Hunnedalen fra om lag 600m. Grovkornet, ikke gjenfrosset, men kompakt snøoverflate. Fra om lag 800m dukker ørlite grann svært kram og kompakt fokksnø fra tirsdag opp i østlig sektor. Fint skiføre på gammel grovkorna, fare for sug på fuktig fokksnø.

Avalanche Danger Assessment

1 Low Gunstige forhold. Kompakt bærende snøoverflate til tross for manglende nattefrost. Relativt kjølig og minimalt med solinnstråling begrenser faren for våte løssnøskred. Glideskred kan fortsatt forekomme. Muligheter for noe mer sol i morgen øker faren for vått løst i sør. Ellers status quo. Forecast correct Fint varsel nå.
