 | | Trend |
|
New wind slabs will be easily triggered today, and have the chance to avalanche naturally. A lull in the weather this afternoon and tonight will provide a chance for the snowpack to adjust to the new load.
In the Backcountry
New snow yesterday and last night combined with strong gusty winds has created wind slabs on many slopes near and above treeline. Expect to find these slabs easily triggered as they are resting on a variety of weak layers and good sliding surfaces. On shadier aspects surface hoar and surface facets will inhibit bonding of the new snow. On sunnier slopes sun crusts will allow new slabs to slide off easily.
Travel Advisory
Be aware of areas with deep new snow and dense wind slabs. Take the time to quickly check the bonding with the new and old snow. Windslabs can carry propagation far, creating wide avalanches, even if they are relatively shallow.
