New snow and wind loading have formed reactive storm slabs.
Make conservative choices and be very wary of exposure to overhead hazards, especially while the sun is out.
Up to 40 cm of new snow may be forming reactive new slabs at all elevations, but will be particularly be prone to triggering on wind-loaded soples near ridgetops.
New storm snow is expected to become reactive with solar warming. Watch for natural wet loose avalanches, particularly on sun-exposed slopes.
On Sunday, the region saw natural and human-triggered avalanches up to size 1.5.
Natural and human-triggered avalanches remain likely on Tuesday.
Up to 40 cm of new snow has blanketed the region. Strong southerly ridgetop winds have likely formed thicker and more reactive slabs on leeward slopes. The new snow sits over a variety of old snow surfaces, including surface hoar, crusts and facets. Expect the potential for a poor bond at the storm snow interface.
Up to 100 cm is currently sitting over the early February crust that is thin and breakable on northerly aspects to 2300 m and thick on southerly aspects.
A widespread crust and facet layer from late January is buried around 100+ cm deep.
