Hakuba currently sits under mainly clear skies with clouds shrouding the upper peaks. This should burn off as the day temperatures warm up. A small dusting of snow yesterday evening (1-2cms) was eagerly enjoyed by all but it tapered off by 9PM. Strong winds were observed yesterday from the NW making for windpacked conditions in the backcountry. On-Hill conditions are currently packed powder and groomed with some vicious moguls formed over the weekend. Wind will also be a factor today on the hill as the forcast is calling for moderate winds 25km/h from the NW.

Our trained avalanche forecaster and weather guru is still out and his absence has been extended to the 18th of March (Sorry, now the 20th), so the in-depth weather observations from Hirakawa Study Plot are put on hold til then.

Todays's Avalanche Hazard follows....play safe out there powderhounds!


Above tree line: Considerable

Tree line: Moderate

Below tree line: Low

N.B. As was noted previously: these hazard levels will likely increase with the daytime warming. Compression tests conducted on SE aspects of Shizenyen area were as follows;

CTM (9) RP@ 9cm down on / 0.5~1.0
CTE (4) RP@ 9cm down on / 0.5
CTH (24) SC @ 104 cm down on facets and / 0.5

A steep temperature gradient was observed in the snowpack (between 70cm (-8.4) and 140 (-3.4 cm) which contributed to the facetting on the 104 cm layer.

Travel Advisory:

People heading off-piste today should be cautious in wind loaded areas and in areas that exposed to direct solar radiation. Last weeks snowfalls combined with the high winds have contributed to exteremely variable snowpack conditions. Hard wind scoured ice/crust on ridges exposed to wind and soft deeper snowpack in lee sided gullies and concaved terrain. Steeper terrain will be more affected by the sun today and may become unstable by later morning or afternoon.
