|Avalanche Advisory published on May 31, 2014:||Issued by Nick Meyers at 10:53am|
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.
|danger scale:||1. Low||2. Moderate||3. Considerable||4. High||5. Extreme|
Spring sun with warm daytime highs and above freezing overnight temperatures can allow for loose wet snow instabilities like roller balls, pinwheels, and loose wet snow sluffs to occur during the spring time on Mt Shasta. While most of these loose wet avalanches should remain too small to bury a person, they could still push a person into an area with undesireable consequences or where terrain traps exist. Larger wet loose avalanches are unlikely most of the time; however, they are not impossible. Loose wet snow avalanches can start small and entrain more snow as they move down the hill and potentially gain size. Expect wet loose activity during the mid-day hours and/or warmest portions of they day on E - SE - S -SW facing slopes. Pay attention to who is above and below you, whether you're skiing or climbing.
SPRING STATEMENT: The Mt Shasta Avalanche Center has shut it's doors for the season. Thanks for all your support. Be sure to check the Climbing Advisory also!
The primary avalanche probem for our spring snowpack will be loose snow instabilities. This type of instability is most often in the form of roller balls and pinwheels which usually don't pose a threat. However, larger wet loose avalanches can and do occur on Mt Shasta during warm spring conditions and are of more concern. Typically, these types of slides will start small and entrain more snow as they move down the hill. They will generally move much slower than a dry slab avalanche, however can still easily bury a person, especially when terrain traps are involved. Expect wet loose activity during the mid-day hours or warmest portions of the day on E - SE - S -SW facing slopes. It's not often we see climbers trigger wet loose slides, however we do see skiers trigger them. Be mindful of people all around you. Look above and below you and have keen situational awareness. We can all play together out there and be safe, if you pay attention.
Spring time brings us the possibility of corn snow, powder or rain. Remember it is possible for spring storms to dump impressive amounts of snow and/or rain. Most of the avalanche activity associated with these spring storms occurs during or shortly after the storm event. Timing is critical when playing in avalanche terrain.
If during the warmer parts of the day you see signs that the surface snow is getting warm, such as snowballs rolling down the slope or you find the snow is sloppy enough that you sink in to your boot tops, it would probably be a good idea to play it cool and find another slope to play on or under, or call it a day. If this does happen, avalanches can be triggered. If the snow only freezes at night, an early start will be imperative. The snow does soften quickly and will become increasingly unstable throughout the day as it is warmed by solar radiation. If the snow is soft early in the morning due to a lack of freezing overnight, it is probably a good idea to play another day.
Terrain: Remember most of the terrain that we like to play on is greater than 30 degrees. Avalanches are possible on anything steeper than 30 degrees. Avoid cornices, rock bands, terrain traps and runout zones of avalanche paths.
The Five Red Flags of Avalanche Danger any time of year include: 1) Recent/current avalanche activity 2) Whumpfing sounds or shooting cracks 3) Recent/current heavy snowfall 4) Strong winds transporting snow 5) Rapid warming or rain on snow.

THIS SEASON: 4-14-14 Since September 1st , we have received 13.79 inches of water, normal is 37.93 inches, putting us at 36% of normal. For the year of 2014, Mt Shasta has received 10.97 inches of water with normal being 22.05 inches which puts us at 49% of normal. And lastly, for April we sit at 31% of normal, receiving .56 inches of water, normal is 1.80 inches.
Always check the weather before you attempt to climb Mt Shasta. Further, monitor the weather as you climb. Becoming caught on the mountain in any type of weather can compromise life and limb. It is not uncommon for late season storms to arrive and create winter conditions on Shasta. Be prepared.
