The weather report was changing up the vibe every few hours with today's forecast changing from rain to snow and back again but the bare feet in the kitchen test proved that the barometer doesn't lie and we are firmly in the plus temperatures today as well. Currently light to moderate rain is falling on the valley and with positive temperatures measured higher than the top lifts and Goryu reporting 0 cms new snow we can assume it just wasn't cold enough up there for popsicles to stay lickity-sick.

The good news is that the freezing level is lowering through the day and we can expect snow from late afternoon/evening with flurries continuing through the week.

Avalanche Report:

RAIN! Rain! rain…

Over 24 hours of fairly solid rain up to 2000 metres here in the Hakuba Valley. 36 hours of rain come 0700; 100210. This has of course seen deep penetration of the dry virgin powder that we had only 2 days ago turn into a metre of wet and moist (↓0-100cm) riding on top of a stiff slab (↓100-150cm) over a low density sandwich with the old rain crust (210110 / 280110 MFcr ↓150) that continues to grow facets and loose cohesiveness. The mountains will be flushing the weighted wind and soft slabs that did not come down in the last storm now that they have been super saturated by the present stationary front.

Avalanche Activity:

There were multiple natural slab avalanches on all aspects but the east, north east aspects, in steep convex terrain below trees, rocks and cornices have proved the least stable of the slopes pre the rain. Due to low visibility from valley bottom today not many avalanches, other than Roof slides that proved to be fast, heavy and sets up very quickly, were observed but are expected through the duration of the rain and after until the surface re-freezes.

Travel Advisory:

Stay out of the backcounrty, stay to the groomed piste or make it a clean up the house and have an onsen day. But if you must go into the backcountry stay to very low angle slopes, stick to the ridges and be aware of hazards above you. Stay well back from cornices as they are heavy and will step back at least twace as big.

Avalanche Hazard:

Alpine: High
Tree Line: High (Trending to Extreme with continued rain)
Below Tree Line: High
