Steep Deep Japan Hakuaba weather data for the 24 hours to 7am for 860m asl Max temp -2C, min temp -7.5C. -6C at 7am. Barometer 914mbar and steady in the last 3 hours. 3cm new snow. Wind is light in the valley, but most likely moderate in the peaks.
Field observations: I did not record any snow profile data yesterday, in fact I didn't travel in the backcountry at all on the basis that the avalanche risk is currently too high. Winds were moderate with stronger gusts aloft from the north. There are reports of a burial on a south facing ridge in Hakuba, terrain features usually assumed to be safe(r) for travel on unstable days. I don't know the details, but the buried person was found alive after 5 minutes of beacon search and digging.
Please also refer to the Hakuba backcountry travel advisory from the guides at Evergreen Outdoors.
Hakuba weather forecast for the next 24 hours: overcast, clearing slightly, very light snow above 2000m, same temperatures and wind speeds as yesterday.
