This is the last forecast of the season. Start and finish your trips early to maximize good travel conditions. Steep Northerly terrain could still have deep instabilities which may cause large avalanches. Have a good summer!

Summary

Weather Forecast

Cooler temperatures and overcast skies will continue until Wednesday when we will see some sunny periods. Light snow flurries will continue in higher elevations. By Friday, the weather will warm sufficiently that more showers will occur in the valley bottoms.

Snowpack Summary

A spring snowpack now exists in the forecast area. Clear nights with below freezing temperatures will make a supportive snowpack and good travel conditions. If no freeze occurs, it will become isothermal and melt quickly. Northerly aspects may still retain some deeper instabilities that could produce large slab avalanches during warm weather.

Avalanche Summary

Redistributed storm snow may produce avalanches to size 2 on lee aspects and lee terrain features. Northerly aspects in the alpine have lingering deep snow instabilities that may produce larger avalanches later in the season. Warmer weather will result in loose snow avalanches from steeper terrain on warm, sunny days.

Confidence

Problems

Storm Slabs

Storm slabs may continue to build with the ongoing snow flurries in the next few days. Pay attention to windloaded pockets in steeper terrain and avoid them.

Conditions are greatly improved, but be mindful that deep instabilities are still present.

Aspects: All aspects.

Elevations: Alpine, Treeline.
