I thought I found a conditions & avy bulletin here earlier this season, but no such luck now:http://www.sepaq.com/En/IndexDirectEn.cfm?LeParc=4
This also used to work:http://www.wul.qc.ec.gc.ca/meteo/pre...aspesie_a.html

I do have one data point for you, which is admittedly lame, though I suppose it's helpful since you're starting from zero data points:
We stayed at the Gite in mid-July 2000 - "Why yes dear, of course I'm packing up all my ski mountaineering gear in the car, would you like me to bring yours too?" She did refrain from making fun of me during the *entire* drive, but probably only b/c that became monotonous after 12 hours.
Bringing my ski gear was not all that crazy, since they'd had excellent skiing in early July, but then huge rains had taken most everything away by the time we arrived. Some 400/500' vert sections remained, but we were there to hike & bike, and the longer sections were far from the trail, etc.. (Deviating from the trail is very much frowned upon.) If you private message me I can send you some pics, which will convey a good sense of your worst-case scenario.
