Forecast Addendum - 12/03/2021 - 07:00am

Submitted by nmeyers on Fri, 12/03/2021 - 5:32am
Recent Observations: 

Over the last 24 hours on Mount Shasta, winds have been light, temperatures have been above 40°F peaking at 55°F with very little snow settlement. The height of snow at the Old Ski Bowl is 20.5 inches (53 cm).

October and early November precipitation brought a solid base of snow to Mount Shasta. Even with warmer temperatures, that base still lingers above treeline. Mid-week, snow depth was 14 in (35 cm) at 8,000 ft and 32 in (80 cm) at 9,000 ft.

Snow surfaces are variable. Expect areas of wind textured snow above treeline. Slide-for-life conditions exist up high. Be leery of hidden obstacles if snow becomes soft. There are plenty of visible obstacles as well.

Climbers should be prepared for falling ice and rock.

Climbers and skiers will find mostly continuous snow up Avalanche Gulch approximately 1/4 mile above Bunny Flat. Expect patchy conditions for the first bit, then better near and above treeline.

 

There is no usable snow at Sand Flat. The road above Bunny Flat is closed and bare to Panther Meadow.  Do not drive above the gate. There is no snow at Castle Lake and the lake is not frozen. In the Eddies, there is little to no snow.

Mountain Weather: 

Clear days with sunshine and cool nights will continue to host our early December weather through the weekend. Daytime highs will linger in the 40's to 50's and lows in the mid 30's for below and near treeline areas. Winds are generally light, though expect breezy conditions over ridge tops and other exposed areas above treeline. Air stagnation will be an issue in the valleys as high pressure keeps the lid on things. Our next best chance at wintry weather is early Monday morning. Hang tight!
