Lo esencial

Much of the southern bulletin region sits over a strong mid-pack which bridges the deep persistent weakness. Continue to exercise caution near shallow, steep features or terrain traps.

Moderate winds over the weekend have created isolated new windslab over a mix of surface conditions (facets, surface hoar, crust).

Use caution in shallow snowpack areas where deep weakness would be more reactive to a human trigger. An avalanche of this nature would be large with severe consequences.

Weather Forecast

Expecting a steady pattern in the weather for much of the week; cloudy with some sunny periods. Little precipitation and temperatures between -15 to -8. Light west to SW winds, with moderate gusts from the SW. A detailed mountain weather forecast is available from Avalanche Canada.

Snowpack Summary

New wind slab in the alpine can be expected at ridge tops and immediate lees. 10cm of new, low density snow lies over a mix of old surfaces (facets and/or surface hoar). This, over a generally strong mid-pack sitting on the deep persistent weaknesses of facets and depth-hoar.

Avalanche Summary

No new avalanches observed or reported from the Parks field team, a group of AST students and a guide in the Parkers region. Thanks for the Input Crew!Be a part of the Avalanche Forecasting team by reporting your field trip this weekend on Avalanche Canada's Mountain Information Network.
