Cautiously stepping out!

Cold daytime temps will lock-up our moist snowpack for the next while. Expect isolated periods of higher hazard in areas with strong solar influence.

Snowpack Summary

Settled HN over a moist snowpack on solar slopes and, on all aspects, BTL. Mar 23rd sun crust (all elev.) and MFcr (all asp, up to 2100m) are present in the upper snowpack. Isothermal melt/freeze snowpack below 1700m.

Avalanche Summary

Significant natural and explosives controlled avalanche cycle up to sz 3 wet slabs on solar aspects, all elevations. Spring diurnal cycle in full swing!

Confidence

Freezing levels are uncertain

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
