August 8th - Up to 100cm forecasted in Switzerland – no joke

**paedde** · 08-08-2007, 01:21 PM

Well at least above 3000m

Here are the details from SLF

National avalanche bulletin no. 164
from Wednesday, 8 August 2007, 18:30 hours
Considerable avalanche danger and heavy snowfall in the high mountains
________________________________________
Current conditions
From Tuesday, 7 August, until Wednesday, 8 August, the snow line sank from initially about 3800 meters down to 3000 meters. A top of the highest summits of the Bernese Oberland, about 20 cm of snowfall, elsewhere lesser amounts. Light winds from varying directions prevailed. On Wednesday morning it was predominantly dry before intense precipitations set in at midday from southwest.
________________________________________
Development
By Thursday midday, 9 August, widespread and intense precipitation is expected. Afterwards the intensity of precipitation will diminish. The snow line will descend to about 2500 meters. Above approximately 3000 meters on Friday, 10 August, generally 50 to 100 cm of snowfall is expected. Moderate northerly to northeasterly winds, in the high mountains intermittently strong winds, will prevail. In the high mountain regions, fresh snowdrift accumulations will form.
________________________________________
Warnings of avalanche danger for Thursday
In the high mountain regions considerable avalanche danger (level 3) will generally prevail. The avalanche prone locations are above approximately 3000 meters, primarily on those slopes where the new snow and snowdrifts accumulates on glacial ice or old snow. Single persons can trigger avalanches. In addition, during the intense snowfall, isolated natural avalanches are possible.
In those areas where the new snow falls on bare spots, snow slides on the ground can cause a fall in exposed terrain.
________________________________________
Outlook
On Friday, 10 August, on the northern flanks of the Alps and in northern and central Grisons above approximately 2500 meters, some snow will fall. In the Valais, in the Engadine and on the southern flanks of the Alps it will remain dry. The winds will decrease in strength. On Saturday, in the Valais, in the Engadine and on the southern flanks of the Alps it will be partially sunny. In the remaining regions it will be variable. Through the radiation and the daytime cycle of warming, on Friday in the Valais and on the southern flanks of the Alps, then on Saturday in the remaining regions as well, wet snowslides and avalanches can be expected. The avalanche danger will diminish as of Saturday in the Valais and on the southern flanks of the Alps, as of Sunday in the other regions as well.

**H-man** · 08-08-2007, 01:28 PM

Fuck yeah, snow already in the Northern Hemisphere ... jonesin pretty hard now.

**The Dad** · 08-08-2007, 04:38 PM

For those of you playing along from this side of the pond, 202cm is about 81".

**comish** · 08-08-2007, 04:50 PM

Wow! Looks to me like snow down to 2500m in Zermatt!

**alto** · 08-08-2007, 06:49 PM

Could result in disaster, no?

**Kevo** · 08-08-2007, 06:58 PM

They had summer weather last winter and winter weather this summer. Seems very strange. I would suspect that this could indeed result in disaster if it warms up again very quickly- avi danger + flooding

Can we get a drool smiley?

this isn't cutting it here.

you do realize it's a glacier, no? only 30cms of that is fresh...

i'm thinking of going on saturday....IF it opens, IF they clear it, IF there is viz...

**subtle plague** · 08-09-2007, 01:54 AM

confirmed snow down to Zermatt at 1600m.

Ulrichen at 1346m also shows 0.6 degrees so most likeliy it has been snowing there too.

new snow is not as much as far as i can see around 30cm at the slf stations at 2200-2300m. but they are situated too low because most of the snow was above 2800m i'd say. The snow level sank during the heaviest precip so at least half of it came down as rain.
The berner Oberland around Grindelwald has already gotten 100l /m². so up in the mountains above 3200m+ it could be 1m of fresh.

**philippeR** · 08-09-2007, 02:54 AM

Snow forecasted over 2000 m in all the northern alps actualy. The Col de l'Iseran (highest french pass, up the tarentaise) is closed because of last night snowfalls...

And the Tignes glacier is closed ?! WTF ?

Still in Wales

....at least it' stopped raining at the moment.

**subtle plague** · 08-09-2007, 04:04 AM

im still quite confused about one SLF station because the gr. st. bernhard got 120l of precip at the official station and im not sure if this came in the form of snow.
the slf station about 15km west at 3000m says 144cm snow of which over 110cm would be new if the data is correct.

i'll bet it's a data entry error. i've seen them make mistakes such as 114 instead of 14.

**subtle plague** · 08-09-2007, 07:38 AM

normaly i'd say yes, but this time it would fit because they had 30-40 before and st.
bernhard got 120l at the official station. (hand measured precip wmo standard)
