Forecast Discussion

You need a Mount Shasta summit pass if traveling above 10,000 feet. A wilderness permit and human waste packout bag are also required. All of these items are available for self-issue at the Bunny Flat trailhead or Mount Shasta Ranger Station. Annual passes are available at the ranger station during business hours (Mon-Fri, 8 a.m - 4:30 p.m.).

On Mount Shasta, near treeline temperatures remained above freezing in the last 24 hours peaking out at 51 degrees F. Winds were calm to light.

Overall, the snowpack is stable, firm, and shallow and is disappearing below 5,000 ft. Many rocks are scattered across the snow, fallen from exposed patches above. Snow surfaces are variable and, in places, covered with wind-blown cinders and sand.

Wind protected, sun-exposed aspects have been softening up during the early to mid-afternoon hours.

Weather and Current Conditions

Weather Summary

High pressure will bring another spring day - sunny weather, light to moderate winds, and temperatures in the high 40s.

The high will begin to erode tomorrow setting us up for a blast of cold air from the north on Friday night. Snow levels could drop to as low as 2,000 ft. By Saturday night, we could see up to 6 inches of snow.
