hey, It's hard to give avy advice b/c if you die, we'd feel awful guilty. so any decision you make is your own. 
That said, glaciated volcanoes generally have a lower avy hazard, and with such a stable snowpack for the mega-heat wave, I doubt any new activity is enough to worry about.  
Check the avy forecast before you go, assess the snowpack on your own by digging pits in as many types of terrain as possible, and bail if you are in the least bit concerned.  
I'd go, however.
