Watch for a warming trend with possible inversion conditions on Thursday. Combined with clear skies, this may produce a cycle on Solar Aspects.
Weather Forecast
Discussions indicate steady temperatures and minimal precip through Wed evening with North winds. Thurs morning may be the start of a warming trend as winds shift back to the West. There is potential for inversion conditions that may cause a spike in avalanche activity and affect surface conditions treeline and above.
Snowpack Summary
2cm of HN sits above a thin suncrust on S aspects. 5cm to 10cm of recent HST now hides thin windslabs found in open lee areas treeline and above produced by moderate SW winds. S and W slopes are predominantly scoured with crossloaded features. Up to 350cm in loaded areas at treeline with 200cm being the average.
Avalanche Summary
Avalanche activity in loaded lee alpine features over the past 48hrs. Likely triggered with light loads, probably sluffs from steep terrain above. Depth 0.5-1m but not steeping down to Nov 6 mfc. Aspects ranging from E to NW.
Confidence
Timing, track, or intensity of incoming weather system is uncertain on Thursday
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
