Since sometime in the predawn gloom the gentle pitter-patter of rainfall on the roof woke me. At the 0730 hrs. I measured 5 mm of water in the rain gauge. The forecast valley weather is for clouds with rain until mid-day, then the precipitation is to resume in the evening. A high temperature of 14 C and winds getting to "moderate" strength from the west around mid-day. On Tsuga Ike yesterday there was good coverage, at least on the main run down from the top of the gondola to the bottom station of the same. The patrol seems to be doing a good job of marking the hazards as they appear. But remain aware as hazard marking bamboo poles can quickly melt out and over.

The cloud ceiling at the Happo One Lift Company was at the Usagi Daira / top station of the gondola (1,400 m a.s.l.).

Yesterday there were consistent moderate winds from west / south-west at ridge top. The powder skiing was good above 2,200 m a.s.l. on east exposures and considerably lower on sheltered north aspects. So be of good cheer, the good stuff is still out there you just have to really want it.

Of note is that the lower Sakka Lifts at the Happo One Lift Company are closed.


The Hira Kawa Snow Study Plot (830m a.s.l.) 0730 hr. reading is:

Sky: Overcast
Temperature: Present: 5.5 C
Maximum: 12.0 C
Minimum: 3.0 C
Wind at surface: Calm
Winds aloft: Light from the south-west
Precipitation: Raining
Barometer and trend: 910 hPa and steady
Height of new snow in 24 hours (HN24): 0 cm
Total depth of snowpack (HS): 27 cm
Water: 5 mm
Foot penetration: 5 cm
Surface: melt freeze crystals , 6 mm crystals, wet
Density of surface snow: not observed
Crust: no crust
Cloud ceiling: 1,200 m a.s.l.



Above tree line: Considerable

Tree line: Considerable

Below tree line: Considerable

N.B.: Increased loading (snow with wind transport above and at tree line and rain below tree line), today's forecast high under an overcast sky is 14 C in the valley floor, isothermal snow pack at lower elevations with little or no supportive crust and saturation of the snow pack over buried crust layers all lead one to consider the avalanche hazard as "considerable". With the increasing wet loading of the isothermal snow pack the chances of sudden failure to ground is increasing. Be careful of where you stop and be aware of what is above you.

Travel Advisory:
As the saying goes "You should have been here yesterday." With good visibility the above tree line terrain yielded acceptable powder skiing above 1,700 m a.s.l. on north aspects, and down to 2.200 m a.s.l. on east aspects. Of note there was consistent moderate gusting to strong winds that were scouring and loading well down below the ridge tops. There were two size two, natural trigger, avalanches observed: one in the Garagara Zawa (Happo One's north side) at 1,800 m a.s.l., north-east aspect; and one from the ridge top of Korenge Yama at about 2,600 m a.s.l., south-east aspect.
