the weakness is deep, but it could wake up with temp rise
How is the temperature below freezing, but it is raining?

Generally unfavorable, except the 20 degrees or less makes it a pretty benign place.
small release, planar slope, no vegetation
incline
no wind effect, small releaase, timber
additional decission points
20 degrees with terrain trap is hard to imagine
avoiding the glade with the 25 x 25m potential of course

Unllikely to have these slabs on 40 degree plus terrain
It may have mature timber but a 50 m by 50 m glade is pretty big

only positiv is the fact that the slb is small
most likely would need more weight to trigger than one skier, very deep slab
Despite observing signs of recent slab activity my assessment indicates very slight chance of triggering .This almost completely due to low slope angle.
Due to low slope angle and depth of weakness
Low slope angle again key to this assessment. To me so much would depend on if there would be significantly steeper parts above the average 20 degrees
to me it sounds like the layer is failing, but not propogating easily, the temp change may affect this for the worse
the weakness is deep and will be harder to trigger, the slope is not steep, but someplaces it can be triggered, no doubt
if skiers are affecting this layer it should go with every skier
triggering most likely from shallow spots in the variable snowpack
but will it run anywhere?
you might trigger the slope or those adjacent perhaps but it's not going to go anywhere
This very hard. This looks exactly the sort of run we retreat to at times like this. If you can guide around the 25x25m slope - give 'er because trees will hold it all together
How much wind?

small avalanche, deep slab
not steep and  no vegetaion, but unsuported
the terrain trap tips the ballance here in combo with depth of the layer
if it pulled onto this shallow slope mybe it could take you into the terrain trap
again worst case, if it did trigger onto flat terain, could it pull you into that terrain trap, therefor I ahd to rat it sa ride a ride with small likelyhood
depth if it did go and go into that terrain trap would be vey serious
depth of fracture and terrain trap make the combo worse
thick slab big slope but luckily no terrain trap
given the slope angle, unlikey to run far, and no terrain traps  but depth of the slab might pose pushes it to my rating Vs no risk
A lot depends on where the skier is on the slope when avalanche is triggered.
