Summary

Weather Forecast

Mixed sun and cloud forecast for Tuesday with freezing levels rising to 2200m. Upper elevation winds will increase to the mod to strong range by the afternoon.

Snowpack Summary

Surface crusts or "dust on crust" exist on all aspects to 2000m. In the alpine 10-25 cm of recent snow overlies crusts on solar aspects and dry snow on northerly aspects. Good freezes overnight make for solid crusts in the morning that become soft or corn-like in the afternoon (depending on aspect).
