Overall, LOW avalanche danger exists for all aspects on upper elevations of Mt Shasta. Lower and mid elevation snow has now melted.

Normal caution is advised.

Watch out for rockfall and always wear a helment when climbing Mt Shasta.

SPRING STATEMENT: Overall, LOW avalanche danger exists for all aspects and elevations on Mt Shasta. Wet loose instabilities such as roller balls and pinwheels and potentially larger wet loose slides should be of concern on warm days with above freezing overnight temperatures on E - SE - S - SW facing slopes.

Normal caution is advised.

Carry a beacon, shovel and probe and know how to use them!

Overall, LOW avalanche danger exists for all aspects and elevations on Mt Shasta. The avalanche danger will rise to MODERATE for small to medium size human triggered loose wet avalanches  on E - SE - S - SW slopes during the warmest portions of the day. Natural avalanche activity is unlikely.

Carry a beacon, shovel and probe and know how to use them!

Overall, LOW avalanche danger exists for all aspects and elevations on Mt Shasta. The avalanche danger will rise to MODERATE for all elevations on  E - SE - S - SW aspects in response to above freezing overnight temperatures and warm daytime highs. Small to medium size human triggered loose wet avalanches are possible during the warmest portions of the day. Natural avalanche activity is unlikely but not impossible.

Carry a beacon, shovel and probe and know how to use them!

MODERATE avalanche danger may form on sun exposed E-SE-S-SW-W aspects during the warmest portions of the day, especially above treeline. Loose wet snow avalanches will be possible on slopes steeper than 35 degrees. Larger slab avalanches remain unlikely, however small to medium wind slab avalanches triggered by a skier/climber will be possible today.
Overall, LOW avalanche danger exists for all other areas.

Carry a beacon, shovel and probe and know how to use them!

The avalanche danger for all aspects and elevations is LOW. Isolated pockets of MODERATE wind slab and loose snow avalanche danger exists, especially in complex or extreme terrain on N - NE - E - SE aspects.

Normal caution is advised.

Carry a beacon, shovel and probe and know how to use them!

The avalanche danger for all aspects and elevations is LOW. Isolated areas of MODERATE wind slab instability may exist, especially in complex or extreme terrain on N - NE - E - SE aspects.

Normal caution is advised.

Carry a beacon, shovel and probe and know how to use them!

The avalanche danger is MODERATE with pockets of CONSIDERABLE for near and above treeline wind and storm slabs (>8,000 ft) on all slopes, steeper than 30 degrees.

Below treeline, all aspects, the avalanche danger is LOW.

The avalanche danger is CONSIDERABLE for above treeline areas (>8,000ft),

MODERATE near treeline, and

LOW for below treeline areas, all aspects and slopes steeper than 35 degrees.

Today, the avalanche danger is LOW for below treeline areas, all aspects.

Near and above treeline, MODERATE avalanche danger exists on NE-E-SE slopes.

Use caution on mid to upper elevation NE-E-SE, wind loaded slopes, steeper than 35 degrees. The avalanche danger will increase as more snow is added to the snowpack from the current storm and wind loading.

The avalanche danger is LOW for all elevations and aspects. Normal caution is advised.

Carry an avalanche beacon, shovel, and probe and know how to use them when traveling in the winter backcountry.

Snow conditions on Mt Shasta are smooth and firm in the AM hours. This poses risk for a long slide for life should one slip and fall. Ice axe, crampons and self-arrest skills are required for a safe climb...and ALWAYS wear a helmet!

Today, the avalanche danger is LOW for all elevations and aspects. Normal caution is advised.

LOW avalanche danger means that natural and human triggered avalanches are unlikely, but not impossible.

Below and near treeline areas on Mt Shasta, all aspects, the avalanche danger is LOW.

Above treeline, isolated areas may host small to medium size wind slabs with MODERATE avalanche danger on NE-E-SE-S-SW-W aspects.

Moderate avalanche danger means that natural avalanches are unlikely; human triggered avalanches are possible.

The avalanche danger is MODERATE for above treeline areas. Wind and storm slab avalanche danger will increase through the day on all aspects, above the rain/snow level. Near and below treeline areas will host LOW avalanche danger and likely receive rain on snow.

Today, overall MODERATE avalanche danger will form on sun affected slopes, E-SE-S-SW-W aspects, 35 degrees and steeper. Above freezing temperatures last night and warm daytime highs today will cater towards loose wet avalanches on said aspects. Loose wet avalanche instabilities will increase as the day warms.

March 7, 2014 at 7:06 am

A thick crust due to rain on snow has created LOW avalanche danger for below and near treeline areas. Above treeline, for elevations > 9,000 feet, MODERATE avalanche danger exists for wind slab avalanches near ridgetops and bowls.
