CAC Special Public Avalanche Warning Notification

Canadian Avalanche Association

The Canadian Avalanche Centre’s Public Avalanche Warning Service is considering issuing a Special Public Avalanche Warning for the coming weekend. We are thinking:

  • There’s been a number of unusual/surprising avalanches that occurred after the storm ended and during the cooling temperatures.
  • Some of these avalanches appear to be going deeper than the storm snow, which suggests a deep persistent slab problem involving persistent weak layers in the snowpack.
  • Some of the PWLs are unusual for the snowpack climate(s) in which they exist and all of them are not obvious to recreationists:
    • Weak basal facets where early season snowpack was shallow, throughout the Columbia Mtns, especially in the Cariboos, east Monashees, and Selkirks
    • November crust (especially in the Purcells)
    • Early December surface which includes suncrust, facets, and surface hoar (especially on South aspects in the east Monashees and Selkirks)
    • Mid December facets on crust in the Kootenay-Boundary and South Rockies regions.
    • Surface hoar in the South Chilcotin mtns, perhaps some lingering surface hoar in the Duffy area of the South Coast Mtns.
  • Riding conditions at lower elevations may not be very attractive due to crusts from rain and/or warm temperatures. This tends to drive recreationists into the alpine, where the likelihood of triggering an avalanche is greater.
  • Long range weather suggests a benign pattern with near seasonal or above seasonal temperatures  in most regions, a series of small, fast-moving systems that produce light accumulations of snow, and winds of variable strength and direction. This will also contribute to promoting riding at higher elevations and in lee areas.
  • With only minimal amounts of new snow and non-obvious problems, we are concerned recreationists may push out into marginal and more complex terrain.
  • We’re worried that we may be entering a low probability-high consequence scenario where non-event feedback hides a significant problem and skews decision making.

I value your opinions, comments, and feedback. My questions to you are: do you think our take on conditions in your area is reasonable? Do you have anything to add to our assessment of conditions and human factors? Do you think the conditions in your area warrant a special warning to the public?

Avalanche Warning

The Canadian Avalanche Centre has today

issued a

Special Public Avalanche Warning

for the South Coast and Southern Interior.

There are major concerns as storm systems this week have deposited large amounts of snow in these areas,

the weather is changing the snow pack  and the weather forecast for this weekend is for blue skies.

Terrain choices will be critical. Choose SIMPLER terrain.

Website Improvements

I am constantly making changes and trying to improve existing features as well as adding new features to our website.

The calendar is working properly now so that when you click on an event, it will open up in the middle of the calendar.

We now have a Facebook page to help put the word out about our club. There is also a link on the right side of the website showing the latest updates on our Facebook page. I am currently working on an automatic post update for the Facebook page as well as having the Facebook updates show up on our website.

There is also a subscribe button on the bottom right of the page. Subscribing will keep you up-to-date with any new posts.

If you have any questions or ideas for the club, send me a quick note!

Thank you,
Larry Messaros
