Know the weather = know the snow pack = know the stability.
Steep Deep Japan Hakuba weather data for the 24 hours to 7am for 860m asl Max temp -1C, min temp -11C and -10C at 7am. 4cm of new snow in the last 24 hours with a density of 80kg/m3, equivalent to 8.7% water - getting lighter. Barometer has risen to 921mbar and the skies are at last clear and blue this morning. Wind aloft is moderate from the north west.
Field observations: We did not travel in the stormy backcountry yesterday, rather spent the afternoon building an igloo for a friend and saved our energy for this week of potentially clear weather.
Please refer to the Hakuba backcountry travel advisory from the guides at Evergreen Outdoors.
