Yesterday was a strange one..... started off with rain, turned into snow and ended up being fine with clear skies. The forecast got it really wrong there. Today though looks like it will be spot on with clear skies early on and the forecast for good weather all day. It should also really warm up this afternoon with a high of 14 degrees on the forecast. It is already 6 degrees at 7:30am.
Lower slopes around town are getting really thin on the ground (with the ground visible in parts) right now and the temperature today won't help much there. We'll be posting more info on planned resort closing dates soon, though some around town will surely not stretch into April....
Nighta tonight is at the following resorts in Yuzawa: Naeba Iwappara
After a mixed bunch of weather yesterday - and a fresh layer of snow to enjoy - this morning the skies are clear for the most part and it looks like it will be a fine day with mild (almost warm) temperatures. Even early on it is above the zero mark, currently +3 here in Maruike. Expect it to warm up further and for a fair bit of snow melt to take place today. Better conditions early on...
More fine weather forecast for tomorrow too.
The following resort plans to be open for nighta tonight: Ichinose Family
Clear morning, with heavy cloud and wind moving in this afternoon.
No new snow, but a beautiful sunrise over Taisetsuzan national park this morning. Furano was a frosty -5 C overnight, with the groomers doing their part to recover from a slushy afternoon yesterday. According to the resort staff, groomed conditions are excellent this morning. But get your turns in early, because we are expecting a warm storm front to hit by noon, bringing high winds and likely some rain to the area. Temps will hit about +5 by late afternoon as the warm air continues to blow through.
Tomorrow will also be warm and stormy, with base temperatures predicted to reach as high of +7.
The weekend is still looking promising, with temperatures heading back well below zero, and a good chance of snow on the radar.
Think snow, think powder, think a little more winter! Read more ...

Blue skies, spring in the air (and pollen)
As forecast, it's going to be a scorcher today. It was already nearly 20º in downtown Myoko before 9 a.m. and Suginohara is reporting that it's 11º there this morning. It's 10º at Akakura Onsen and the slopes are slushy. A bit higher on the mountain, Chuo was reporting 2º. Break out the suntan lotion and beach parasol.
Also as forecast, the temperature remained well above freezing overnight, with balmy breezes blowing in out of the southwest. There's no wind this morning and visibility is excellent, despite all the pollen and "yellow dust" in the air. The yellow dust is doubtless also contributing to the slushy conditions. On the bright side, the slopes aren't that crowded.
No snow in the forecast for the coming week and high temperatures still predicted for tomorrow, with a bit of rain tomorrow evening. Not a good prognosis.
Blue skies and warm temperatures today...definitely a Spring morning. 2 degrees at the top of Goryu and runs near the bottom of the mountains and getting steadily more desecrated.
A high of 18 degrees is predicted for this afternoon...t-shirt weather basically in effect, don't forget the sun-screen.
Tomorrow looks set to be more of the same with another very warm day forecast...
SNOW STABILITY INFORMATION
Monday's rain left lower elevations with another melt freeze crust and a rapidly disappearing snow pack in the valley. The freezing level was 1000 metres and the snow quality was progressively better with elevation. The new snow fell on wind altered snow on the Northern aspects‚ sun crust on the Southern aspects and on rain crust below 1800 metres. The new storm snow of March 15/16 started falling at relatively warm temperatures and progressively cooled through the night‚ hopefully‚ assisting the Crust / New Snow interface to bond. During the storm on Happo North faces surface instabilities were observed as multiple size 1 loose snow avalanches were triggered in 30 degree plus terrain. This new snow may be starting to bond to the past surface layers but there will definitely still be instability at the crust/ past snow surface and the new storm snow or possibly with in the new snow layer itself. Staying to supported terrain is good sense.
Past melt freeze crusts may also become reactive with the weight of the new snow‚ rain and intense solar radiation. The addition of wind loaded snow will increase the chance that slabs down to past melt freeze crusts and may propagate from shallow points near ridges and around rocks and trees on solar aspects. These type of slab avalanches could be observed Monday morning on Happo One and other east aspect alpine areas. Be aware of what is going on down deep in the snow pack as progressed faceting at those persistent weak layers around past crust could be weakening the bonds below and above the crusts.
March 16th Compression tests on Northerly aspect of Happo @ 1900 metres a.s.l. found Easy‚ Moderate and Hard results in the recent snow storms. CTE(1‚2)SC down 10cm just under old rain crust that was once again exposed by wind. New snow on this layer could cause the layer to sheer below the crust and propagate out wide. CTM(17‚19)SC down 55cm at past laminated rain crust that is seemingly breaking down as it is turning to facets. March 15th Compression tests on Northerly aspect of Nishi Hiodori @ 1850 metres a.s.l. found Moderate and Hard results. CTM/H (19‚22) RP down 45 cm on grauple layer at March 11th interface. RB5 SP down 43 cm on same grauple layer. March 10th Compression tests on a Northerly aspect of Nishi Hiodori @ 1900 metres a.s.l. found Hard results. CTH(27‚23)B down 33cm March 9th Compression tests on a Southerly aspect of Happo One @ 2200 metres a.s.l. found easy results around a buried sun crust down 10 cm. CTE/M(7‚11)SC down 10cm below sun crust. Compression tests on a northerly aspect of Happo One @ 2200 metres a.s.l. found Easy to hard results that also had Sudden Collapse fracture characteristics. CTE(1‚2)PC down 2cm; CTM/H(17‚21)RP down 38cm; CTH(24)SC down 47cm (all Crust and facet related) March 8th Compression tests on an Easterly aspect in the Tsugaike Seicho valley at 1800 metres a.s.l found very easy results just below the recent breakable rain crust at 11 cm. CTE(1‚2)SC down 11cm on decomposing crystals size 2. There were also Moderate compression‚ Sudden Planner results at the past storm snow / February 26th rain crust interface. CTM(15)SP down 59cm on decomposing crystals size 1~2. The layer to keep an eye on was much lower at 133 cms from the surface at the interface above the even older rain layer that is still retaining heat and a lot of moisture and has mixed forms of facets and decomposing snow right above it. There were varying results on this layer from easy shovel shear tests to moderate and hard sudden planner results from compression tests. This is definitely a layer to keep an eye on as if it goes on this one‚ expect a very large and destructive slide. CTM/H(20‚23)SP down 133cm on mixed forms and facets over a thick rain layer
Avoid steep gullies‚ bowls and wind loaded lee slopes. Possibility of triggering avalanches in the past and recent storm snow in certain terrain such as‚ steep lee slopes or cross loaded gullies from rocks and cliff bands‚ convex and unsupported slopes‚ from trees and solar radiated slopes and cornices. Keep travel to supported slopes and be careful of run outs from above. Use proper spacing in more complex terrain and solar radiated slopes.
Avalanche Hazard Rating:
Below Tree Line: Moderate Tree Line: Considerable trending to High on solar aspects with intense mid-day time warming and solar radiation. Alpine: High all aspects
Grauple layer under new snow High density new snow over lower density snow layer Rapid air temperature increase Cornice fall Rapid settlement of surface snow causing load on buried weak layers Increase in loose snow avalanches and suffs Extreme radiation and warming of southern exposures Warming of surface snow causing instability in surface and near surface layers 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. Due caution on cross loaded slopes Poor bonding at or around buried crust Facet layer around buried crust Stay away from steep and convex terrain
Danger level 4 : High
Natural and human triggered avalanches likely.
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 beautiful sunny morning in Nozawa. Visibility is great but temperatures are warm. It is currently 3C on the mountain and in the village. There is a 20km/h South-Westerly blowing. The lower section of the resort has not fared well in the warm temperatures of the last few days, and as such there are patchy sections on Karasawa and the bottom of Skyline.
The forecast is for Thursday to be much the same as today but Thursday night temperatures will drop and snow should fall through to Friday morning on the mountain. Saturday and Sunday are both looking warm but early next week the freezing level is expected to drop well below the bottom lifts.
Currently closed courses are Kandahar, Challenge 39, Kurokura, Hachiman and the bottom of Schneider.
Well, some time early this morning, my secondary stage light shield (the one I hang up behind the shoji screen) decided to magically drop on to the floor. Not amusing when one is planning to stay in bed a little longer - only to be woken by 'meboushii' - a very bright environment.
So yes, it's nice and sunny this morning, the sky is blue and there is minimal wind. The temperature is already 8 degrees Celsius. So we're probably talking tropical conditions by lunchtime. Read more ...

Overcast with strengthening winds
Yesterday was very mild and there was a little rain/sleet mix in the morning. Today is also very mild with well above freezing temps at village level. Snow conditions are very springlike and this warm weather is expected to continue into tomorrow with some rain on the way. From Friday it will cool down somewhat and there is a little snow in the outlook into next week. Currently the last week of March is expected to be much cooler than this week and we will hopefully see out the month with a few more snowfalls. The snow up around the peak is very icy and the access gates are likely to remain closed today.
