New Avalanche Danger Scale for 2010/11

2

There is a new unified avalanche danger scale rolling out for the 2010/11 season that will create a common vocabulary between US and Canadian avalanche centers, according to Powder Magazine.

It’s not immediately clear to me what the major differences are here. It retains the Low/Moderate/Considerable/High/Extreme methodology with similar explanations for each danger rating.

Whatever the differences are, you can get accustomed to the below image on your friendly neighborhood avalanche center website.

Via Powder:

Backcountry avalanche centers across Canada and the United States will be using a new avalanche danger scale for the 2010/11 season. The new scale reduces some of the ambiguity of the previous scale, provides more definitive travel advice for backcountry recreationists, incorporates risk by referring to typical avalanche sizes expected, and utilizes icons recently adopted by European countries.

    The new Danger scale should help a large amount BC skiers (and sledders!) make smarter choices. By coming right out and telling folks things like “careful snowpack evaluation is essential”, BC travelers will hopefully take the time to make appropriate terrain choices. Especially when conditions are floating in that considerable zone.

    Hey Rich! Thanks for chiming in. So I guess the main difference is more detailed, more straight-forward and plain language than, for example, the scale here: http://www.sierraavalanchecenter.org/advisory

    Makes sense to me.
