Avalanche danger is low and normal caution is advised for another day of sunny skies and warm temperatures. West/northwest wind will check back in on the mountain.
Watch for falling rime ice below ice crusted cliffs. Any climbers on steeper terrain may also encounter firm, slide-for-life snow conditions.

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

Overall avalanche danger is low. Backcountry hazards will be limited to challenging, knee wrenching ski conditions, slide for life climbing conditions and over head hazard due to ice caked cliff bands. Oh yeah, we wouldn't want those exposed rocks and trees feeling left out, they are also part of the show.

Recent Observations

The powder hounds are bummed, but the corn snow lovers have their nose to the air, sniffing about. Tuesday's storm capped off the snowpack with a widespread rain and wet snow crust, up to an inch thick. Smooth, firm and icy conditions on the upper mountain are likely and slide for life conditions may exist. Rime ice is a hazard for anyone venturing below ice plastered cliffs. Wear a helmet or just avoid these areas. You couldn't buy an avalanche at this time and snow surfaces are challenging: icy and firm, breakable crust to sticky and gloppy during the heat of the day. All trees have shed their snow. Temperatures soared to 63° F in town yesterday, 50° at the Mt. Shasta Ski Park at 1400 hours. Winds were calm.

Weather and Current Conditions

Weather Summary

There is nothing but sunshine in the box for the foreseeable future. Temperatures are down right balmy this morning. While the general trend is for things to cool off into next week, today will be another warmer one with highs in the mid to upper 40°s F. Tonight's low is right around freezing. Near and above treeline, expect those pesky west/northwest winds to blow. Next best chance at precipitation is later next week.
