As someone who has backcountry skied in Washington for the past 15 years color me interested!<p>What are the weather inputs into the models and do you think that will capture enough? Wind transportation seems easy enough to think about but stuff like hoar frost seems harder to predict using available weather data, but maybe that's just clear cold days?<p>I do wonder as well whether the models should actually be regionally specific. Sure avy patterns are different but that likely falls out if you are basing it all on weather. IE, WA can act like CO when we have many weeks in a row of cold and vice versa during warm spells there.<p>Anyways, will be keeping an eye on this. Enabling places with no current forecast to have something at all is a noble goal, though I am skeptical that the recent WA deaths would have been prevented, that's just education and group dynamics sadly.
