Crusts can be expected on solar aspects up to 2400m but northern aspects are still holding dry powder snow. With the warm temps and strong solar input, early starts are recommended. Watch for increasing westerly winds overnight building windslabs.

A few loose wet and dry avalanches were observed throughout the field day on Friday. No new Slab avalanches were noted.

The upper snowpack remained dry above 2000m on northern aspects with very little wind affect noted. Solar aspects were getting moist by 1100am and by 1300 moist snow was found on all aspects below 2000m.

Recent mild temperatures are helping the snowpack settle out and slowly strengthen. The March 24th crust is down 50-60cm and this interface is staring to become less reactive.

Expect to encounter windslabs in alpine terrain along ridgelines but these slabs do not extend far downslope. With the forecasted increase in winds overnight, this problem will become more common in open terrain.

Saturday is looking to have a mix of sun and cloud with some isolated spring time flurries. Temps in the alpine will be around -5C with a freezing level rising to 2200m throughout the day. Winds are forecast to increase to strong out of the west overnight.

• Carefully evaluate steep lines for wind slabs.
• Be alert to conditions that change with elevation and sun exposure.
• A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
• Travel early on sun-exposed slopes before cornices weaken with daytime warming.
• A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
