The recent new snow that fell in sept has created a 93 cm Wind slab on all lee slopes (NE Aspects). This wind slab is bonding to a layer of Facets with no CT results. NO signs of instability were seen on the lee slopes.
We have indicated that the layer of concern is the 93cm of wind slab sitting on the Facets. If this bond release there would be a very large avalanche. |

The recent new snow that fell in the last week has created a 55cm Wind slab on all lee slopes (NE Aspects). This wind slab is bonding to a layer of Poly Crystals with no CT results at this layer which we see as the layer of concern.
Moderate CT results were seen at 10cm and 100cm. |

20cm of Strom Slab has fallen this week.This has fallen on a Melt / Freeze layer and is showing no signs of instability.
We are seeing Hard CT results @70cm and this is our layer of concern. Also seeing Moderate CT results were seen at 45cm. If the layer at 70cm releases it will create a large avalanche. Use caution if skiing lee slopes. |

The recent new snow that fell in sept has created a 12cm Wind slab on all lee slopes (NE Aspects). This wind slab is bonding to a melt / freeze layer with no CT results. NO signs of instability were seen on the lee slopes.
We have indicated that the layer of concern is the 12cm of wind slab sitting on the melt / freeze layer @ 12cm. We saw a sudden collapse while performing an ECT which failed at ground level. |

The recent new snow that fell in the last week has created a 20cm Wind slab on all lee slopes (NE Aspects). This wind slab is bonding poorly with a layer of buried surface hoar @20cm.
Moderate(13) CT results were seen at at this interface and this is our layer of concerm Easy CT (2) results we seen at buried surface hoar which formed mid storm cycle in that last snow event (17cm of new snow). |

42cm of Strom Slab has fallen this week.This has fallen on Surface hoar and is bonding poorly. We were seeing easy CT (3) results on this and got ECT n non propagating results on the 5th tap.
our layer of concern is the Layer of Surface hoar at 42cm. Be aware of the lower buried surface hoar @ 57cm. Use conservative terrain choices when skiing early this season as skiier triggered avalanches are likely. |
