There were several human triggered Dry Loose avalanches observed in Hatcher Pass.
|Signal Word||Size (D scale)||Simple Descriptor|
|Small||1||Unlikely to bury a person|
|Large||2||Can bury a person|
|Very Large||3||Can destroy a house|
|Historic||4 & 5||Can destroy part or all of a village|
3 inches of new snow fell last night and an additional 5-6 inches is expected by the end of the day today. This new snow and old low density snow have created conditions capable of producing Loose Dry avalanches. These avalanches will be small in size and will be found in steep terrain 40° or steeper.
Even small avalanches can have high consequences when traveling in steep terrain. Cliffs, rocks and gullies are all things that can increase consequences. Be aware of what is below you and practice good slough management when traveling in steeper terrain.
8-9 inches of new snow will have accumulated by mid morning today. Winds capable of transporting snow are not anticipated with this storm. This new snow will be sitting on old, sugary, weak snow. This combination of low density new and old snow could create a storm snow problem later today. These avalanches will be small and similar in size to the Loose Dry problem. Use small tests slopes, hand pits and other traveling tests to help identify this avalanche problem. Shooting cracks and whumphing are red flags.
While glide cracks can still be found throughout Hatcher Pass, cold temps have helped increase stability for this avalanche problem. It’s still a good idea to avoid spending time underneath any “brown frowns”. Any new snow that has fallen will make identifying glide cracks difficult.
