Fine weather, clear
As forecast, it is a fine morning in Yuzawa. The sun is out and mostly blue skies with just some wispy clouds hanging on for the moment. It may cloud over later on in the day but generally it will be more of the same and another mild one with a high of around +7 degrees likely later on in the day. It doesn't feel like mid-winter right now and we can only really expect some fairly heavy snow conditions out there particularly in the afternoon.
Tomorrow shouldn't be as warm and a chance of snow by the end of the day and then hopefully colder on Tuesday and Wednesday with a decent chance of new cm of snow to top things up.
A fine sunny morining in the region with a fine day - perhaps some cloud - forecast. It is quite a cold start to the day but should warm up a fair bit before cooling down tomorrow again bringing with it a chance of snow.
Not much else to report this morning - the colder weather is still due around Tuesday and Wednesday bringing with it hopefully some new decent snowfall for us all to play in.
A fairly cloudy start to the day early on in Zao Onsen this morning but blue skies are now on view and hopefully it might clear up more later as the day progresses and end up being a fine day.
Just a sprinkling of fresh snow to report (1cm or so) but it is a fairly mild morning at 0 degrees just now in the village with just a slight breeze out there. It is around -5 higher up on the mountain.
More fine weathr forecast for tomorrow before a run of colder and snowier days from late Tuesday.
Hakuba is again today sitting under clear skies with the sun beaming down on us. Almost spring like at the bottoms of the resorts today with slushy corn snow and soft packed powder to be found, much the same as yesterday. You can expect nice groomers this morning, icier and drier conditions up top and even some good shaded areas may have some pockets of fresh powder.
The temperature today is getting fairly warm with a max of 5 degrees, with light to moderate winds coming in from the north west. The slopes over the past couple of days have been fairly busy, getting quieter towards the afternoon as the weekend crowds head home.
Temperatures will be dropping throughout the week and with it bringing some snow, by Wednesday there should be more snow to keep everyone happy!
On investigation into the Alpine yesterday during extreme wind conditions it was more than obvious that we had intense blowing snow at ridge top and even below ridge line. The South East aspect are heavily loaded and scouring down to the rain crust of the 28th on wind ward slopes. Once again great spacial variation across the mountain. Melt Forms were not found in the upper 120 cm of the snow pack at 2000 metres in a heavily loaded lee slope, however, when probed a lower density layers were found at 130cm and 160 cm down. The 160 cm layer was right above a thin melt-freeze crust. Compression Test at this location (very difficult in the extreme winds) found a CTM Resistant sheer at 50 cm down and further CTH breaks and resistant planar sheers below this in wind loaded snow.
At lower elevation (1450 m) the Rain layer of the 28th was apparent below the new HST storm snow and reactive in Compression Tests on NE aspect CTMPC(12) down 35cm on DF size 1. The rain layer at this elevation was still moist and retaining heat with temperature of 0*C. There was also results above the Jan 21 Rain Crust CTHSP(22) down 90 on DF / RD size 1. The most concerning find was the moist melt forms in the lower half of the snow pack to the ground that will not be freezing as the overall temperature of the snow pack is hovering around 0*C. This lower moist snowpack is resulting in large glide cracks seen at lower elevations and at the ski resorts. Todays warming temperatures and strong solar radiation will not being doing anything to alleviate stresses on these lower layers and could result in slides to ground on steep solar radiated slopes around rocks or trees at lower elevation (1500m ~ 800m).
Use extreme caution when crossing solar radiated lee slopes and cross loaded slopes in steep tensioned terrain or avoid all together during periods of strong solar radiation and mild temperatures. Stay to supported and simple terrain away from cornices and convexities. Watch out for solar radiated hazards from above on traverses out in the valley bottoms and holes over creeks that may be opening up after recent rain and warm temps.
Alpine: Considerable (Cornices, Lee side loading, Steep solar radiated rocks)
Tree Line: Considerable (Cornices, Lee side loading, Steep solar radiated rocks, trees and convex rolls)
Below Tree Line: Considerable (General warming of entire snowpack, Steep solar radiated slopes)
Relatively warm conditions with blue skies and light winds.
It was a perfect full-moon last night with clear skies and no wind. This has made way for nice firm packed and freshly groomed runs this morning.
Given the day is going to be relatively warm, the best conditions will be earlier this morning before the snow gets a little soft.
For those eagerly awaiting the next dump, you probably won't have to wait too much longer. We have a good fall of snow expected between Tuesday night and Saturday morning. So start waxing your powder skis and boards.
Another beautiful spring day...midwinter. Warm temperatures, blue sky and sun. Another cold night last night so the slopes this morning were pretty hard. There's a lot of people up at the resorts this morning and all the traffic has scraped off a layer of sugar to sit on top of the hard pack.
It's great to have such nice weather but right now we would swap the blue sky for some snow as we've been pretty fortunate with good conditions this season and would like to be kept in the manner to which we've become accustomed. Read more ...

Becoming overcast with light snow
A truly magnificent day in Niseko. There was around 30cm of snow since last report and bright sunshine for most of the day to enjoy it in. Sure it got a little mild and the snow down lower a little heavy but especially for those of us here all winter to see the sun from time time is really appreciated. Currently it has become overcast again and a little light snow is starting to fall. The snow will becoming much heavier later tonight and the temperature will drop to well below freezing again and we certainly won't be seeing much sun for the rest of the week. Near blizzard conditions are currently forecast for Tuesday and Wednesday so make sure you get out there tomorrow before the storm hits.
Current Official Snow Depths:
Grand Hirafu: Top - 310 Bottom - 190
Niseko Village: Top - 340 Bottom - 200
Annupuri: Top - 295 Bottom - 200
Niseko Avalanche Info No.46
Moiwa base: -6℃, 30cm of overnight snowfall. Coastal data: WNW10m/s at Benkei cape, WSW11m/s , 2.0m waves and 1016hp at Kamui cape. Annupuri peak: -9℃, WSW 9.3m/s at 6am, topped W30.7m/s at 22:00. 30cm of fresh snow at the peak as well as in lower altitude. No notable weak layer has been observed and the snowfall transition is relatively stable. Avalanche hazard is low. Peak gates are scheduled to open at 10:30. Follow the ski patrol’s instructions. Steep 40°slopes such as in the Backbowl or in further Higashi-one should not be ridden too easily. Strong skiing stimulations could trigger avalanches from deeper layers (Jan 22nd, 25th). A lot of skiers/snowboarders are expected to be in the mountain on Sunday. Refrain from cutting cornices, dropping into the same slope at the same time and remaining in gully bottoms. Always close the peak hut’s door behind you. Have a nice day.
Today should be the last day for a while to get out and enjoy those above freezing temperatures we have seen more than our fair share of this week. At plus one degree celsius, you might want a sweat band rather than that knit hat. But this unusual warming trend isn't even slated to last the night. Come late evening, we should be seeing temperatures steadily dropping alongside significant snows, and the next seven days will be a return to more seasonal temperatures.
The ski resort was pretty busy last night and today with a festival, including all sorts of games for young and old alike. Consequently, most of those precious snowdrifts along the sides of the runs that were bolstered by a random 20cm shot in the arm from two hours of heavy snow last night were riddled with tracks, but all in all it is a solid day to be up on the mountain, especially if you aren't a fan of bitterly cold weather but you still enjoy winter sports. The snow is still light and fresh from the all the storms we saw this week, and there was hardly a gritty or icy patch on the mountain. The fireworks last night were the best I've seen in a while, and if you have kids traveling with you, Kitanomine was definitely the place to be today, with all sorts of games and prizes being handed out like candy. Because they were candy. Read more ...

Sunny, increasing clouds
It's been a nondescript Sunday in Myoko; it started sunny, then got increasingly cloudy. The rumors were that it would be very warm, but it never happened. The snow, too, was neither here nor there; a little hard in places, a little soft, not exciting but not bad to ski on. Anyway, as a wise skier once told me, you have to bring your own fun to the slopes, too.
The forecast ahead looks better, though, with light snow and colder temperatures on Monday, and the chance of heavy snow on Tuesday. Backcountry, dig around and see what's going on, as there are two layers at about 25cm and again at around 70cm—the lower one is much looser and unconsolidated, although a compression test yesterday didn't yield much—no significant or clean breaking without some hard hits. Hopefully things will remain stable of some more heavy show falls.
