Weather Forecast

A typical diurnal pattern is expected for the rest of the season with variable and increasingly higher freezing levels occurring daily. Forecasted Spring storms are expected and could easily produce heavy snowfall, poor visibility and hide exposed hazards like rocks and stumps. Get after your objectives early.

Snowpack Summary

A seasonally typical melt freeze cycle. This building crust will continue to bridge a weak, isothermal snowpack on most tree-line and alpine slopes. This crust will break down over the day and become increasingly hazardous for triggering with rising temperatures, solar input or rain. Dry snow can be found at the highest elevations along the divide.

Avalanche Summary

Spring afternoon cycle can be expected daily as the season closes.
