Still good feedback for NWAC to consider.

I like the CAC and Utah presentations better than NWAC; but I liked the previous discussions on NWAC more than the present; I do contribute to NWAC and CSAC and I am pretty chagrined that we can't come together enough in the country to provide comprehensive services and R&D in a whole range of sectors; it is nice we're going to get some new weather radars.

How is the Canadian one more useful? It's can be misleading and dangerous because what may be Considerable on a south slope could be High on a north slope. The Canadian model doesn't take into account windward / leeward slopes and other critical factors. The NWAC model is far more informative. My $.02 anyway.

I stand corrected, I see further down where they show additional details. Guess I should have scrolled all the way down first before opening my big mouth.... :/

I like the direct links to recent avalanche incidents in the Canadian format.

I don't have a favorite as far as the presentation or layout goes. I do like the addition of the avalanche rose and find it to be the first thing I look at. 

As far as treeline vs alpine, that is obviously a valuable distinction especially with respect to wind, however, in the Cascades in the winter during relevant avlanche periods there is essentially no access to above treeline terrain that is meaningful and hence little data, whereas Canada has so many commercial operations.

Elevation distinctions are critical in the Cascades and also the S. Coast mountains of BC because of the proximity to the ocean and lower elevation terrain in general but are seldom that relevant in the interior of BC because of the height of the terrain, the existence of arctic air and the mean latitude regarding temperatures during a winter storm. Elevation does become more relevant in the interior as one approaches spring. So, I guess I understand why the NWAC format works better here while the Canadian model works well there.

This is incorrect.
