I never participated in the SJ forums luckily, I remember that was a ski.com.au vs SJ beef tho!
Haaaaaaaa.
30 cms at Cortina today. Every run was brilliant. Hardly crossed a track. The wind was very kind last night. I was thinking to ski the Acoop carpark but 0cms on snowjapan report where the JMA station is. Thankfully I didn't listen to them.
So true that. So often surprised as well, as I was today. I try to get out there even when I know that it is not going to be good. It will make me a better rider and ready for those moments in time when you hit a random patch of crud. I also want to be able to give accurate reports of conditions and you can't do that when you just want to ride pow. People think I am crazy but I actually enjoy spring time moguls. Once they have softened of course
OK, now JMA is redirecting me to this fancy new page::
https://www.jma.go.jp/bosai/map.html#7/34.5/137/&elem=temp&contents=amedas&interval=60
Actually looks like an improvement on the old interface. Shock horror!
Even lets me distract myself at 10 minute increments rather than 1 hour.
well above zero at the top of the Aomori gondola, this is what last March looked like
It has reached 441cm. JMA started recording snowdepth at Sukayu in 1980. So, 40 years and I noticed the 8 biggest snowdepth of February (for Sukayu) are in the last 20 years. The numbers are NOT snowfall but the biggest snowDEPTH of February (Edit : Sukayu has the biggest snowdepth around March 10th on average)
1st = 566cm - 2013
2nd = 496cm - 2012
3rd = 464cm - 2000
4th = 453cm - 2006
5th = 442cm - 2005
6th = 439cm - 2018
6th = 439cm - 2019
8th = 428cm - 2001
When it comes to "yearly snowfall", the biggest is 2,376cm of 1996.Last edited:
Brilliant day today. With pow too
Not much happening on the forecast. GFS gives a short sharp shock on Tuesday and then nothing until around the 10th.
To tell you the truth, the map with all of the temperatures is an improvement, but the rest of the new JMA site is a complete mess.....
You can't find anything intuitively any more. The old 7 day city forecasts were a good visual summary, but the new one is confusing IF YOU CAN FIND IT!!!! I found it once, but can't find it again!!
Instead of having a concise menu at the right, you have to go Home, every time. (twice!!)
I like the map w/ temperatures, and I like if you click on an observation station you can see more data in one place. Plus it does cute little graphs.
To be honest I had my favourite pages and had just saved the links, so never really navigated around the site. But like you am getting hopelessly lost trying to find equivalent things on the new site.
One thing annoying me is that the earthquake page that gave the previous 7 days' data in a list seems to have disappeared... That link now takes me to a rather sluggish map which is nice, but I want a list too!!!
Yes, this is what I mean.....
For the list of quakes, go to the bottom right corner with the magnifying glass and "more".
But that's the point, it's not intuitive!!!!

Got it, thanks!
One thing that crossed my mind is whether the new interface could be a precursor to making access subscription based...
I remember a storm in a teacup last year about them deciding to put ads on the website to boost revenue.
tbh the amount of data up there free for anyone is incredible. Amazing resource. Long may it last...
And for 7 day forecasts, instead of clicking on "one week forecasts" like the previously, you select daily forecasts, then "table".
Weird, not a breath of wind here, but leaden skies. The forecast says rain from midday but looks ready to start any minute now.
Looks like it depends on topography... (how exposed, vs nearby mountains)
Hakuba 0.8m/s (~3kph)
Nagano City 5.4m/s (~20kph)
Itoigawa 12.4m/s (~45kph)
The new snow surface at my place looks like this
Had that happen here a couple of weeks ago. Snow is mostly gone now, except for in the shade. We weren't blessed with any decent snowfall in Feb so what looks like "snow" is actually solid ice.
Drizzling now but still cool @4 degrees.
@BobGnarly @Asama
Wow, warm day all over central Japan (Yokohama now 18.9C)
HOWEVER, Kanazawa hit 21C degrees at 5am, it has now dropped to 7.4C at 11am.
It's also dropping on the coast of western Niigata, with Itoigawa at 11.6, after hitting 17.5 at 7am.
The southerly, then easterly winds that brought warm air, is turning to the northerly.
However, the high is dominant over the Asian mainland, so I wouldn't expect any lengthy period of northerlies bringing snow. (Reasonable snow soon, above 800m, then lower, but not past midnight tonight)
It has dropped down to 10c here too but began raining heavily.@BobGnarly @Asama

Yeah the difference between Iiyama at 400m ish and Madarao village 1000m wrt temp and rain v snow is quite amazing.
The temp change today without a front going through is quite amazing is well. Looking at the maps, so different to Aus where we would expect a cold front with those low pressure systems and that sort of temp change.
Temperatures have dropped sufficiently for snow in northern Nagano & near the coast in Niigata resorts above 500m.
Still too warm in central Nagano & northern Gunma.
Briefly changed to snow around 30 mins ago here, but too warm to settle... seems to have reverted to sleet for now.It has been such a heavy snowfall in Furano that the local road clearing crew lost control and the town has been a bit of a mess all day. We get big falls for sure, but are more used to regular top ups in the 20-40 cm range, not lots of really big ones and this one was (and still is) a doozy. It's been snowing non stop for about 24 hours, with almost zero visibility at ground level for most of the day, which also added to the chaos on the roads. Pic off wife's car this afternoon around 180m ASL. Got some digging to do tomorrow when it is due to clear. Thursday morning might be Tokachi.
Feels like winter has packed up and left early... can't see anything of interest on the horizon.
Used to March being quite up and down, but seem to be stuck in "up" mode. Haven't seen a proper snowflake in weeks!

Nuff said really. That and the complete lack of posts in here...
It still does sort of support the idea that you get 2.5 months of snowy weather in central Japan.
The Nagano branch of the JMA releases a monthly summary of the previous month's weather.

This March just gone was the warmest on record for 28/30 locations in Nagano pref (if I counted correctly), beating the previous record by 1C or more in many cases (most of which were records set in 2018). Sure the story is similar in many other regions.
It seems discussion of AGW is a bit taboo in these threads, but... ouch!
Snow currently accumulating at Manza onsen (1800m)
Not much use for skiing but not bad for May!
