A sunny day sweepin the clouds away. Watch for rising temps at the noon hour, falling back hard at night. The sun should tuck back from early afternoon with snow starting again late night.
The powder is still good atop most resorts, and Suginohara was a bit crowded with boarders yesterday (mostly group/school outings) so don't expect it to be empty as usual. Read more ...

patchy cloudy sky with sections of blue and occasional sun
Chilly again today, yesterday remained cool throughout the afternoon and evening, even the parks had hard landings. Lot's of powder to be had yesterday, the buttery type, the kind of snow that satisfies when you slice through it with your near 2 meter metal rimmed high tech plastic knife (your snowboard or skis).
Patchy blue sky this morning with light cloud above 2000 meters, the sun is managing to shine on parts of the mountain whilst others remain grey. Read more ...
Nozawa Onsen Now!

Fine at the summit. Overcast lower on the mountain.
It is overcast in Nozawa this morning. No new snow reported for Yamabiko last night. It is cloudy down in the village but blue sky at the summit at present, with a very light westerly breeze. The snow condition is still very good. Temperature is currently minus 6C at the summit and minus 4C in the village.
The weather will close in during the day, with the wind increasing slightly. Light snow should fall on the mountain from the afternoon through tonight. The next few days are predicted to bring cloudy conditions with some light snow and snow showers. Moderately heavy snow is expected to fall friday night.
All lifts are expected to operate today except; Yunomine Mizunashi Utopia Challenge Hikage #2 B
Well yesterday remained relatively fine with only brief, light snow showers. Overnight it cleared a little and temperatures started to plummet. In the early hours of the morning though snow started moving in over the region and has been reasonably heavy at times. There is a nice layer of fresh powdery snow across the resort again. The snow is expected to clear though later in the morning. With light winds over the last 24 hours the snowpack has settled and the avalanche danger has lowered significantly. All gates are expected to open today but care should still be taken around cornices and on convex slopes. Tomorrow is expected to warm above freezing at village level as a low approaches from the west. Wet snow will start falling across the region later in the day and temperatures will remain mild until later on Friday. Cold temps and plenty of powder are still expected right through the weekend.
High cloud today with the sun poking through and cold temperatures with nice groomed runs this morning warming to plus zero temps now.
No snow overnight but with no wind today it will be a nice one on the skifield. Yahoo are calling for more rain on Friday though if it falls in the valley we can expect it to fall as decent snow at elevation.
Also more snow on the radar beginning on the weekend.
SNOW STABILITY INFORMATION:
The early morning valley rain of January 19th soon turned to snow and proved to be a very good amount of snow at elevation. There was 45 cm at the top of Tsugaike gondola at 1500 metres and 30 cm at Goryu Alps Daira by the end of the storm. This storm snow has begun to settle and is bonding despite the two 10cm deep Grauple layers that are the only sign of weakness with in the new snow itself. This new consolidating slab is over riding the newly formed sun crust from Saturday's strong solar radiation. Slope tests in the Tsugaike area between 1800 m and 2000 m during the JAN Avalanche Training School found that the new storm snow was sliding in ski cuts and hand tests on the solar exposed slopes. Wumphing associated with propagation over a large area was observed during a slope switch back cut test. The slope did not slide as it was a supported concave slope below tree line. This shows that larger wide open south facing steep convex slopes especially slopes that have scoured rocks and ridges or areas of shallow snow pack leading into steeper and deeper avalanche terrain.
Tests on more shaded aspects were not finding the weakness between the new storm snow and the previous snow fall as on the south slopes but there is still concern about the persisting instability around the December 23rd rain crust found to be down 120 ~ 200 cm. Deep Tap Tests resulted in hard‚ sudden planer fractures down 138 cm on mixed forms and facets overriding the rain crust @ 2000m on a north aspect in Tsugaike. This rain event was quite high in elevation and may still pose a greater Hazard in high alpine terrain on cross loaded‚ steep slopes and stay well away from unsupported slopes peppered with rocks at the surface or just below the snow surface. Take due CAUTION on all aspects in the Alpine such as terrain accessed from Happo or Goryu or even up high on the main Hakuba Ridge. Expect any avalanches coming down in the Alpine to be BIG and do not underestimate run out potential. (Those big South faces from Happo down to HiraKawa river valley are a prime and will decrease in stability with solar radiation and rising air temperatures) WATCH OUT CROSSING RUN OUT ZONES!
Northern aspects have not had the same solar radiation creating the same persistent instabilities as the south slopes. There is instability in the new storm snow and ski snowboard triggered slabs and sluffs in steep avalanche terrain are probable.
The sun crust of January 4th is still a possible concern especially on steep Alpine terrain on solar exposers and there is there is also the Dec 23rd rain crust that is still a concern as we receive more snow and today's possible strong solar radiation puts extra stress on those lower layers.
Grauple layer under new snow Surface avalanches in new snow due to underlying grauple layer High density new snow over lower density snow layer Increased snowfall adding load to buried week layer Steadily increasing air temperature Cornice fall Radiative cooling of snow surface causing low density snow and frost at surface Falling tree bombs (Possible triggers and cause of avalanches as well as overhead hazards) Solar radiated cornices becoming weak with direct solar radiation. Use caution if crossing solar radiated slopes. Increased caution advised around rocky outcroppings‚ cliffs and well spaced trees in start zones. Development of cornices in lee slopes Lee side loading Windward scouring of ridges and rock out-crops creating uneven loading of slopes Due caution on cross loaded slopes Poor bonding at or around buried crust Facet layer around buried crust Wide propagation due to wind slab Stay away from steep and convex terrain
Danger Level Updated at 2009 1/21(Wed) 6:00 Danger Level 3: Considerable. Natural avalanches possible. Human triggered avalanches probable.
Danger level ratings are set for conditions at tree line and may vary from below tree line and High Alpine areas. Use this information as a guideline only.
A partly cloudy day today with the sun poking through at times. The forecast is for the snow to hit later this evening and the current cloud support the forecast. The snow is predicted to continue through to tomorrow morning bringing an expected 25cm to the valley level.
The Minakami forecast for the weekend is for mostly cloud but as there is precipitation forecast for Yuzawa, Tenjindaira and some of the other upper Minakami resorts are likley to get snow over the weekend.
Backcountry A pit dug yesterday at 2000m on the South aspect showed a very solid snow pack with no obvious weak layers. There are large cornices forming higher in the alpine that could release with the slightly warmer temperatures, so travel in avalanche runout zones should be avoided.
Silver grey clouds early this morning with mild temperatures.... no new snow to report and as I write this (at 2pm) it is around 5 degrees. The sun is out too though it's still a hazy look rather than bright blue. It looks like we might get that tomorrow though with fine weather forecast for tomorrow with a high of a warm 7 or 8 degrees. Before that though there may well be some snow overnight as the clouds roll in - though I certainly wouldn't be expecting much especially if tomorrow turns out to be sunny from early on.
While snow conditions are generally fine still, we could do with some new snow. Longer range it looks like it will be snowy over the weekend and into early next week.
Nighta tonight is at the following resorts in Yuzawa: Naeba Iwappara
In Minamiuonuma just to the north, nighta at: Ishiuchi Maruyama Centleisure Maiko Joetsu Kokusai
It has been a fine day in Shiga Kogen from early on, especially once those early clouds moved out of the way and while not brilliant blue skies the sun has been out and it has also been a relatively mild day. Things have clouded over a bit this afternoon though and we may be in for some snow tonight. If it does snow it won't be much snow though, and tomorrow is forecast at the moment to be a fine day here with the next snow lined up currently for the weekend.
The following resort plans to be open for nighta tonight: Ichinose Family
