Overall avalanche danger is LOW. Exercise normal caution. Get back into the avalanche awareness mindset. Use safe travel techniques and bring your shovel, probe, and transceiver. Practice using them. Even the most experienced avalanche professionals need to review their skills.

Recent Observations

Submit Avalanche Observations

A winter storm beginning on November 17th brought close to 20 inches of snow to the Old Ski Bowl. About 15 inches of this still remains. The snowpack is right side up and at least fist hard. A few crusts are intermingled throughout.

Downhill skiers will find the snowpack barely usable, though it may provide uphill and Nordic skiers with a pleasant workout. Snowmobilers are still enjoying it. Tread lightly if leaving the road to the Old Ski Bowl - the snowpack is shallow and many hazards lurk above and below the surface. Boondocking with your new turbo kit is not recommended.

Weather and Current Conditions

Weather Summary

A high pressure ridge off the coast is sending our wintry weather to the far north, a trend that will continue throughout this week, and most likely through the second week of December. Expect dry, clear weather for the foreseeable future.

Our three month weather outlook puts us in a narrow band of normal which could be be a good thing. A normal Shasta winter is a good winter.
