Avalanche danger is LOW. There is still snow out there available for transport, though winds today are unlikely to be blowing it. Nonetheless, continue to pay attention to steep, leeward slopes and blowing snow. There may be some small, isolated wind slabs out there. If you find them, they'll be lens shaped, at the top of start zones, and will crack under your feet. Test for them on rollovers above areas of no consequence.
Recent Observations
In the last 24 hours, about an inch of snow fell near treeline on Mount Shasta. Winds were variable and light, peaking at 9 mph. Temperatures ranged from 10 to 26 degrees.
On Mount Shasta, about 3-6 inches of low density snow exists as you transition from below to above treeline. There is some light wind affect above treeline but no notable signs of wind slab formation. There is still snow available for transport.
Weather and Current Conditions
Weather Summary
Colder temperatures should stick around for the next couple of days. Snow levels will remain near 3,000 ft, though no snow is expected. Low clouds this morning should break into a clear, sunny day by 10 a.m.
Showery conditions return Friday night. Near 0.3 inches of precipitable water and 4,000 ft snow levels should give us another refresh to our struggling snowpack.
