Chances are someone would cut something in a steeper spot (NEAR 40 DEGREES POSSIBLY UNSUPPORTED ABOVE A TERRAIN TRAP).I am not sure how the same slope can be shaded from the sun protected from the wind and recieving significant solar radiation.
an unsupported 30 degree slope that just warmed up to zero likely would be triggered eventually. (I am picturing traversing above a creek on a bench in heavy timber and someone getting too close to the unsupported part)
As the instability is fairly deep and the slope angle is lower certainty of avalanches is lower but find the sweet spot in the steeper areas and look out.
Slope angle <20 degreea trumps instability
as a practitioner my perspective focuses on what happens on a given day and the numbers (Statistics) involved over longer timeframes is difficult to understand as it may be years before identical conditions occur on the same slope
The rapid warming and solar radiation will create a different problem than wind slab but will be an issue.
how can it be protected from wind transport yet have hard winds slabs?
even though a windward slope there may be areas of windslab in gullies or specific terrain features.
I'd be watching for a slab change with the warming temps
Some of the information seems to be irrelevant here; eg; whether or not there is a terrain trap may not have any bearing on triggering an avalanche, however this is a consideration for me!
I just dont see how there can be a slope "protected from any wind transport yet still have "hard wind slabs "and "widespread signs of recent transport"..
This is tough for me. because of how 'protected from the wind' intercepts with winds strong enough to produce hard slabs. If it is fully protected from this wind, risk from wind slabs is near zero, but if wind was strong enough to reach in anyway, and 60 cm of snow then watch out. Kind of need to be there
It all hinges on the 'protected from wind'
but mostly small since it would have to be a 'feature' within the <20 degree slope. Of course, if that results in going over the cliff 3 meters away !
from isolated wind transport
perhaps on the steepest roll on the convexity
if the terrain is protected from the wind , but assuming it is wind affected
X-wind
Its highly unlikely that a slope this large with no significant vegitation would be protected from any wind tranport/affect
I can not answer this question accurately without knowing whether or not a windslab exits on this slope.
based on that there is no windslab on this slope. the snow and slab are sitting on the other side in the lee where there is a high degree of triggering
i don't think its steep enough
could be worse as that sun and air temp work their magic
sorry I've never seen this condition
If a slope is protected from wind transport then there shouldn't be any wind slabs on it.
If it's protected from wind transport then there is no chance of triggering a wind slab avalanche
