Another icy morning. The conditions are poor indeed. With cloudy skies and temps rising in the afternoons, the icing never ends:( Snow comes tomorrow once again, but this long 3-day stint of iced ski resorts has skiers and boarders lodge-bound.
It is an overcast day here in Nozawa Onsen. No new snow has fallen since the last report, and the snow depth remains constant at 210cm on Yamabiko and 160cm on Uenodaira. It is currently -2 degrees in the village and -5 degrees up the top where there is a 25km/h northwesterly.
Yesterday's cold conditions kept the snow in relatively good condition, but there is not much fresh stuff left anywhere in the resort. Lower slopes are starting to get patchy in some places but the runs remain well covered.
Today's forecast is for light snow and snow showers up higher and light rain for the lower parts of the hill. 2cm is forecast for this morning and this afternoon. Tomorrow is expected to bring heavy snow to the upper slopes in the evening, with a mixture of snow and rain predicted for lower altitudes. Thursday should be partly cloudy before heavy rain on Friday right the way to the top of Mt Kenashi.
With a Japanese holiday coming up tomorrow the village is buzzing with tourists and holiday makers - take care in the crowds and enjoy the atmosphere!
All lifts are expected to operate today.
All courses will be open except Mukoubayashi, Kurokura and Hachiman. Read more ...

Just cloudy yesterday and today is starting in similar fashion. No snow to report (both in town and higher up), clouds in the sky and currently about 1 degrees in town. It's a mixed forecast for the day with sun, sleet, cloud and snow all lined up there, but with late tonight and tomorrow set for fine sunny weather once again it seems we can't be expecting much (snow).
Looking at the weekly forecast, right now there is no heavy snow on the horizon - just light snow every now and again.
Recommendations remain - go high!
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
There is no new snow to report this morning and the skies have cleared somewhat leaving us with a fairly fine morning - cloudy but bright with breaks in the cloud that look like getting bigger as the day moves on. Temperatures are remain low which is good news for the snow that we have on the slopes and today there is just a slight breeze. So pretty good conditions to get out there today.
The following resort plans to be open for nighta tonight: Ichinose Family
Official resort snow depths as of 10th February 09:
Great powder runs yesterday up at Kagura, and Naeba for that matter too! Shame for the weekend customers but a nice little present for all those who worked themselves to death on the busy weekend.
No new snow on the ground since the last lot, a very cold night last night. In fact I woke up cold a few times and so had to sneak that dial up on the Denki blanket a little more than usual. Big banks of high cloud today, racing across the sky to match the wind speed which seems to be getting quite high at times, giving us bright sunny spells and sections of blue sky.
Another mostly fine morning with sunny breaks in Niseko. We're really not used to seeing the sun this much in the winter months! Some cloud did move in yesterday afternoon with a little light snow but it amounted to barely a dusting. The winds have remained light and the snow pack has settled well and avalanche danger today is relatively low and all gates will open. Beware of a sun crust on exposed south facing slopes. I'm sure many of us have been watching the updates on snow-forecast for the possible rain event this Friday. It's been switching back and forth between lots of rain to lots of snow to near nothing with every update. Obviously the exact path of the low will make a big difference whether there'll be lots of snow or any rain and the path is very difficult to forecast from a long way out. The latest update has the freezing level getting just above the base of the mountain with large amounts of snow to fall. Obviously whatever happens the precipitation will get a little wet at the base but in the week to follow temps should progressively get colder as the low moves to the north of Hokkaido and strengthens. I'm hopeful this low will remain fairly stationary up north for some time and we should see at least a week of a classic winter synoptic set up with a deep low to our NE and a large high to the west. This will hopefully see cold and snowy weather to continue for much of the rest of Feb.
Blue bird morning, perfectly clear, no wind, turning to overcast with very light snow through the afternoon.
Today started with another blue bird morning. Eager skiers were treated to perfectly groomed runs, no wind, and blue skies with a few centimeters of fresh falling overnight.
By 10:30 conditions are now overcast, with light flakes coming down at a crisp -7 degrees at the base. It looks like this gentle snowfall will continue through the afternoon, and temps will remain well below freezing.
With soft snow all round, unfortunately there hasn't been any new snow for the past couple of days so it means that we have to enjoy what's there. Some good snow was out there to be found by those willing to look.
The snow overnight on Saturday wasn't a lot but it was enough to leave some powder behind. I was up on Iwatake Sunday and winds were raging everywhere but where we were it seemed...not a soul on the upper half/two-thirds of Happo until afternoon might have meant some unhappy travellers. Yesterday there were still some remains to be had but the winds really hammered the BC (see snow stability information below).
After the strong winds of the past few days there was some good snow to be found, and there still might be, but you will have to really look for it! The winds have now calmed and will be picking up again over the next couple of days, with light snow forecast for tomorrow night and sadly rain on Thursday with strong winds. This morning at the top of Goryu the temperature was -3 and will be warming up throughout the day.
In the valley at the moment it is comfortable light jacket weather, when you are out of the breeze and in the sunshine it will feel quite warm. The mountains will be quiet today with lift lines minimal and the slopes clear of weekenders, so make the most of the weather and calm. Please see below for snow stability.
It’s currently overcast with a white sky but rays of sunshine peeking through every now and again. Temps are warm enough now for what snow is left on the roofs to be sliding. The forecast is calling for some precipitation this afternoon but nothing at this moment in time.
Tomorrow looks set to be bluebird with some light snow possibly tomorrow night.
SNOW STABILITY INFORMATION AS AT MONDAY 9th:
Extreme North West winds on Sunday have transported much of the 15-30 cm of new snow that fell across the Hakuba mountains far down the lee ward slopes. The clouds of blowing snow looked like storm clouds coming over the mountains or intense amounts of smoke from forest fires. These intense winds have no doubt scoured wind ward slopes near ridge top and ridge top areas depositing the blown snow a long way down the South and East facing aspects. This new wind deposited snow is over riding the February 7th sun crust and may not yet be bonding well to that sun crust. Lower elevations that were not hit as hard by the winds have 15- 30 cm of new snow resting on past wind effected layers or Feb 7th buried sun crust. Solar aspects at lower elevation received intense radiation on Sunday and will no doubt have a melt freeze crust on the surface today.
February 7th Compression tests on Happo One at 2200 metres found Moderate to Hard results on 30 degree plus South and East aspects down 30-40 cm at the interface between the February 1st sun crust or wind deposited storm snow and the February 5th storm snow. 2 Reuch Block test also found results on this same layer on a RB5. Both Reuch block tests resulted in quick moving slab fractures. A slightly strong temperature gradient was also observed at around the 30 cm - 40 cm layers and faceting crystals were also found at this week interface.
February 8th Compression tests in the Hakuba Norikura area at 1500 m North East found moderate / progressive compressions or breaks down 15-20 cm fracture. Ascending in the same area on South East aspect saw shooting cracks from skis and snowshoes.
Cornices were newly developed and breaking easily during slope testing.
The snow pack in general is very variable in snow depth due to recent strong - extreme winds and intense solar radiation.
Avalanche Observations: 2 accidental rider triggered slab avalanches were observed on East aspect steep leeward terrain on Saturday up Happo One.
Travel Advisory: Be extremely cautious of solar radiated wind deposited lee slopes in steep and convex terrain around rocks and trees. Take due care on windward scoured slopes as it is easy to slip and slide a long way on the exposed ice. Be cautious of semi buried past avalanche debris that is rock hard and may be difficult to navigate.
Avalanche Hazard Rating:
Below Tree Line: Moderate trending to considerable with intense solar radiation on all solar aspects.
Tree Line: Considerable
Alpine: Considerable trending to poor with intense solar radiation or continued wind loading.
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 Rapid settlement of surface snow causing load on buried weak layers Extreme radiation and warming of southern exposures Solar radiated cornices becoming weak with direct solar radiation. Increased instability of solar aspect start zones especially under cornices and very steep 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 Surface hoar frost created overnight Facet layer around buried crust Wide propagation due to wind slab Due caution in steep and convex terrain
The power was wiped out in Minakami this morning after a helicopter hit the main power lines. This caused all of the power in town to shut off and hence all of the ski areas to closed. The power has now come back on and things are back to normal.
Snowing in the upper mountains at present with around 10cm accumulated already today in places above 1300m. Looks like it will not last for too long. Tomorrow sees a warmer sunny day followed by some more snow in the evening. Read more ...
