Points saillants

Warmer temperatures will encourage many to get out an enjoy the new snow.  Keep in mind that the snowpack is still weak and needs more time before pushing into big terrain.

    Storm snow has evolved into a persistent slab mainly around treeline. Widespread whumphing in open treeline areas was enough to keep our forecasting team on lower angle terrain without overhead exposure.

    Caution in steeper and rocky terrain especially on ice climbing terrain.

Weather Forecast

Temperatures continue to warm into the weekend.  Cloudy skies will bring light precipitation and winds are expected to remain light from the south.  Expect some light wind transport in exposed areas like ridgelines.

Snowpack Summary

Last weekends massive snowfall continues to settle prompting widespread whumphing in open treeline areas.  Team had moderate test results (CTM11) on a facet layer above a crust near the base of the pack on an E facing 25 deg slope at 2000m (TL) in the Parkers Area.  Alpine snowpack has more strength with hard results on a similar aspect at 2200m.

Avalanche Summary

No new observations along the Parkway today.
