Recent strong winds have built stiff wind slabs at treeline and above.
The stable weather pattern will keep the avalanche hazard in the moderate to low range. Travel conditions are good, ski quality....not so much.
Recent strong winds have built stiff wind slabs at treeline and above.
Thin areas are locations where it is more likely to trigger this weakness.
No new avalanches were observed or reported.
Surface hoar has been growing over the past few days with the cooler nights. Otherwise not much is changing, and backcountry users can expect a thin melt freeze crust on all aspects up to 2300m, and higher and thicker on solar aspects. Wind slabs are common at treeline and above from the strong winds over this past week with some areas stripped down to rock. A buried surface hoar layer is also being found down 50cm up to 2100m that has been producing results in the hard range.
The November crust is deeply buried in the snowpack down 120-200cm. Recent field tests on this layer have produced no results. There is still some concern for triggering this layer from thin snowpack areas.
The high pressure system persists bringing sunny skies and no precip. Daytime highs should reach -7C at treeline, with ridgetop winds in the moderate to strong range from the NW. No real snowfalls in the forecast for at least another week.
