Bottom Line
Avalanche danger is LOW. The snowpack is thin and hazards exist above and below the surface. Tread lightly. High pressure will keep conditions dry and clear throughout the week. Thank you to our donors who helped us raise over $10,000 during Giving Tuesday!

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
A winter storm beginning on November 17th brought close to 20 inches of snow to the Old Ski Bowl. About 14 inches of this remains in areas unaffected by wind. Ridges have lost much of their coverage.
The snowpack is right side up. A few crusts are intermingled throughout. Snow surfaces are variable. If you are getting out to enjoy the early season snow, beware of the many obstacles that exist above and below the surface.
There is no usable snowpack at Castle Lake and temperatures have been staying mostly above freezing.
Weather and Current Conditions
Weather Summary
High pressure will continue to dominate our weather pattern throughout the week keeping things clear and dry. The outlook for the next couple of weeks does not look good for precipitation. You can check out the California Weather Blog for more details:
This, of course, is bad news for those itching to ski. The good news is the mountain bike trails are in premo shape for riding.
