Snow and weather reports posted on Monday 20th November 2017

Niseko Now!

Friday 9th March 2007, 7:24am
Weather conditions: High cloud.
New snowfall: --
Snow depth: --
Winter is back! Well it lest for the time being. Deep powder, cold temperatures and big smiles. Yesterday was a great one, riding in knee to waist deep and with fewer people on the mountain, more fresh tracks were there for the taking. All gates opened yesterday and the visibility was good to about 900m for much of the day.

Through yesterday and overnight we've had another 10 or so cms. Today the skies will be clearer and the winds lighter than yesterday. We should see some sunshine today and tomorrow morning.

Tomorrow afternoon we should see the signs of the approaching front which will bring us more good snowfalls on Saturday evening and through Sunday. Will just have to keep an eye on the freezing level.    Read more ...
 

Yuzawa Now!

Friday 9th March 2007, 7:49am
Weather conditions: Cloud, sun
New snowfall: --
Snow depth: --
Some interesting things going on with the weather at the moment in Niigata.... there was actually some quite heavy snowfall in central parts of Niigata Prefecture, with reports of up to 70cm (!) in Ojiya, representing the most snowfall of the season.

Unfortunately, here in Yuzawa we didn't get much of that at all - in fact, just a sprinkling at town level. Higher areas will have got more. The clouds have cleared up for the most part and there are some bright blue skies around early on this morning.

In resort news, NASPA Ski Garden have announced that this coming weekend will be the last, with Sunday as the last day open for that ski resort.

It is looking like tomorrow will be fine weather.   Read more ...
 

Shiga Kogen Now!

Friday 9th March 2007, 7:56am
Weather conditions: Cloud
New snowfall: --
Snow depth: --
Yesterday turned out to be a fine day in the end and today is looking to be more of the same with a bright and sunny start to the day and a lot of blue sky on show once again. It was a fairly cold night and there is a fair bit of frost around, but it will probably be warming up during the day today. Tomorrow also looks set to be a fine day with a chance of snow coming back to us on Sunday and Monday.   Read more ...
 

Furano Now!

Friday 9th March 2007, 8:13am
Weather conditions: Snowing.
New snowfall: --
Snow depth: --
Things are looking better here this morning; it is snowing! We have about 5cm of perfect powder snow on the ground in town and it is -6 at the moment so should be a good morning up on the mountain. The sun is trying to break through at the moment and the forecast is giving sunshine later on today but then the forecast didn't predict any snow so it's not very accurate!

Yesterday was another very quiet day on the mountain and all the slopes were nicely groomed but it was pretty compacted in most places especially the lower sections on Kitanomine Zone.   Read more ...
 

Naeba Now!

Friday 9th March 2007, 8:58am
Weather conditions: blue Sky
New snowfall: --
Snow depth: --
So there has been a whopping 1 cm of snow overnight in the village, more up top and lots more in Kagura. A blue, blue sky this morning with -3 sitting on the temperature scale and there doesn't seem to be even a sneeze of wind. There's board testing in Asagai today with the half-pipe opening this afternoon after a week of closure causing misery to many of the locals.

I had a wee look at the weather forecast and it's apparently going to snow Saturday night? So, Sunday morning it is then.   Read more ...
 

Nozawa Onsen Now!

Friday 9th March 2007, 9:56am
Weather conditions: Fine.
New snowfall: --
Snow depth: --
A picturesque start to the day in Nozawa this morning; Clear blue skies, great views, low winds and another 5cm of fresh snow set to make it a great day. Temperatures are currently -8C at the top and -2C in the village. Base depths are 165cm at Yamabiko and 100cm at Uenotaira. Hikage has 15cm. Nagasaka and Karasawa are both closed. Coverage on the lower resort is still a problem causing the closure of most of it.

The outlook is for the possibility of light snow today but tomorrow should be mostly fine until Saturday night when heavy snow should fall and continue all day Sunday.

Hakuba Now!

Friday 9th March 2007, 10:37am
Weather conditions: Few clouds
New snowfall: --
Snow depth: --
It was clear and cold (by local standards) at sunrise with a light mantle of cloud draped on the peak of O Kuro Dake (2,395 m a.s.l.) at the head of the Hira Kawa valley. There seems to be a light wind blowing from the north-west a ridge top. Another 4 centimetres of snow was on the new snow snowboard (HN24) this morning with a significant settlement cone (this indicates that more than 4 cm of snow fell but that it settled rapidly). Yesterday at noon there was 45 cm of storm snow on the melt freeze crust at the top of the Grat Quad (1,850 m a.s.l.) at the Happo One Lift Company. There was only 18 cm at the Hira Kawa Study Plot (830 m a.s.l.). At 1530 hrs. at the top of the Tsuga Ike Lift Company's Tsuga Dai Ni Pera chair-lift (1,700 m a.s.l.) there was 27 cm on top of the melt freeze crust. The crust below this new snow did not soften up appreciably even at the lower elevations. By now the hazards that the new snow was camouflaging should be mostly uncovered but care should still be exercised.

Today's initially clear sky is forecast to become cloudier. The forecast high temperature is 3 C with light west to north-west winds in the valley. No precipitation is predicted until later tomorrow (there is an occluded front approaching from the south-west).


^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The Hira Kawa Snow Study Plot (830m a.s.l.) 0700 hr. reading is:

Sky: Few clouds
Temperature: Present: -6.0 C
Maximum: -2.5 C
Minimum: -7.0 C
Wind at surface: Very light from the north
Winds aloft: Light from north-west (Hakuba incinerator chimney smoke was rising rather straight up but there was slow movement in the clouds at ridge top)
Precipitation: Nil
Barometer and trend: 922 hPa and steady
Height of new snow in 24 hours (HN24): 4 cm, with a few centimetres of settlement cone
Total depth of snowpack (HS): 62 cm
Foot penetration: 15 cm
Surface: New snow crystals, 2.0 mm
Density of surface snow: 100 kg/cubic meter to 130 kg/cubic meter (two samples in the snow below the past 24 hours' new snow)
Crust: 14 cm
Cloud ceiling: 2,300 m a.s.l.

Hazard:

Above tree line: Considerable

Tree line: Considerable

Below tree line: Moderate

N.B. There was no evidence yesterday of any wind transportation happen nor a propensity to form slabs in the storm snow (HST). There was a regional variation in the amount of HST. See introductory statement above in this posting. This morning, with good visibility there was little natural activity observed. There was some sluffing from steep high elevation terrain. One anomaly was a pair of slab avalanches that ran naturally on the flank of Shakushi ga Dake: east aspect; skiable terrain; approximately 2,000 m a.s.l.; slab avalanches; probably wind loading trigger; size two (big enough to cover and/or injure a human). These two avalanches were in side by side pockets that might have received cross loading yesterday. The solar effect might weaken bonds in the snow. Yesterday at noon there was moderate wind observed at the north-north-east ridge crest (1,750 m a.s.l.) above the Virgin Cafe.

Travel Advisory:
There was close to 50 centimetres of storm snow (HST)on top of the melt freeze crust at tree line observed yesterday. See below "field observations" for details. So far there is little sign of slab formation in the HST. There is lots of snow available for transportation so if the wind does pick up... . There are pockets of instability as witnessed by the pair of avalanches discussed above. There were shears observed yesterday in this HST.

Yesterday's field observations:
Happo One Lift Company:
Time: 1100 hrs.
Location: top of Grat Quad, skier's left of designated run boundary fence
Elevation: 1,850 m a.s.l.
Exposure: north
Slope angle: 10 degrees
Sky: Obscured
Air temperature: -4.5 C
Wind: light from south-west
Precipitation: snowing 1 cm per hour
Height of storm snow (HST): 45 cm
Shears: -down 16 cm, compression test easy, sudden planar
-down 26 cm, compression test moderate, sudden planar

Time: 1200 hrs.
Location: top of Grat Quad, skier's left of designated run boundary fence
Elevation: 1,850 m a.s.l.
Exposure: north
Slope angle: 10 degrees
Sky: Obscured
Air temperature: -9.0 C
Wind: light from south-west
Precipitation: snowing 1 cm per hour
Height of storm snow (HST): 46 cm
Shears: -down 16 cm, compression test easy, sudden planar
-down 27 cm, compression test moderate, resistant planar

Tsuga Ike Lift Company:
Time: 1530 hrs.
Location: top of Tsuga Dai Ni Pea Rifuto
Elevation: 1,700 m a.s.l.
Exposure: north
Slope angle: 45 degrees
Sky: Obscured
Air temperature: -7.5 C
Wind: calm
Precipitation: snowing 1 cm per hour
Height of storm snow (HST): 27 cm
Shears: -down 21 cm, compression test moderate, sudden planar twice
-down 21 cm, compression test moderate, resistance planar twice
-down 10 cm, tilt table, sudden planar
Ski cutting tests: no results
There was no evidence of wind transport in the snow. The ski tracks crumbled at their edges strongly suggesting that there was no slabbing tendency in the new snow
There was indications of re-crystallization taking place just below the top of the melt freeze crust that is below the HST.
Despite the difference in the amount of HST from area to area there is a certain continuity evident in the shears. At the top of the Korenge Dake ridge top there was some evidence of slight wind effect observed this morning, but not much. Good skiing was experienced yesterday with pleasant lap splashes a frequent occurrence. In the moderately angled treed terrain the nature of the new snow was such that relatively relaxed cruising was possible.

Minakami Now!

Friday 9th March 2007, 12:11pm
Weather conditions: Clear blue skies (Tenjin - covered in cloud)
New snowfall: --
Snow depth: --
A beautiful sunny day in Minakami with a light Northerly breeze. The sum of yesterdays snow did not add up to much in upper Minakami because of strong winds but there is still a fresh coat of around 10cm on the mountains.

The forecast for the weekend is for a sunny warm day with snow predicted to hit on Sunday. Good news for all weekend warriors!
