This layer is now moist facets and remnants of depth hoar.
The entire snowpack is moist and hopefully cooling with chilly temperatures tonight. We are on a slow moving improving trend, but it will still take some patience to get there.
This layer is now moist facets and remnants of depth hoar.
The firm mid pack will start to bridge this layer as heat escapes the snowpack. This will be a slow process. Continue to limit exposure to overhead hazard In areas that haven't avalanched,
Nothing new today.
A field trip today revealed a much wetter snowpack than first thought. We have about 35cm of settled storm snow resting on top of the Mar 28th crust. The snowpack is holding a fair bit of warmth still and only the top 10cm of the crust layer is frozen. The crust if firm enough that skis wash out on it and occasionally break through. Beneath the crust is 40-60cm of moist, dense snow. The Jan 30th interface is down a meter in places and consists of moist facets. Snow tests today had moderate failures on the Jan 30 layer and slightly better results on the deeper layers. In other words, both the Jan 30 and deep layers are unfortunately still in the game and need to be respected.
Continued flurries will give another few cm's overnight. Temperatures will drop to -12 overnight and rise to 0° by early afternoon. Winds will variable in direction, but very light. Even peak height winds will be light and variable. Expect a fair bit of solar to creep through and make things feel much warmer.
