Avalanche danger is low. Use normal caution as you travel. Though sunny skies, warmer temperatures, and light winds may allow snow surfaces to soften, be prepared for firm, icy conditions and breakable crusts. Bring an ice axe, crampons, and helmet if ascending steep terrain. Expect slide-for-life conditions.

Generally safe avalanche conditions. Watch for unstable snow on isolated terrain features.

Northeast winds have been strong to gale force in the last 24 hours above treeline. Gusts at Bunny Flat could knock you off your feet. I thought there was no more snow to transport, but some was indeed blowing over the Trinity Chutes and the West Face -- probably mostly sublimating.

Snow surfaces are hardened by wind and melt-freeze cycles.Be prepared for teeth chattering skiing and slide-for-life conditions.

This is what Mount Shasta looks like at the moment:

Weather and Current Conditions

Weather Summary

If you are looking for spring skiing conditions in January, today and tomorrow may be the days to venture out. Sunny skies, warm temperatures, and light winds may allow the boilerplate snowpack to warm up enough to give you a thin, soft surface to slide on. Temperatures will peak around 1 p.m.

We'll get a skiff of snow late Thursday night. That cursed, never-ending, high pressure blob that lurks out in the Pacific may actually break down for a bit next week allowing cold temps and moisture to swing in from the far north. Don't jinx it with snow dancing.
