Recent winds and snow will increase wind slab development in the Alpine.
The storm forecast for Saturday day will now arrive Saturday evening. 10-15cm of new snow with light winds. If the sun comes out on Sunday, watch for stability deteriorating on solar aspects due to the solar radiation. Dry snow still being found on high north aspects but widespread crusts in most other locations.
Recent winds and snow will increase wind slab development in the Alpine.
Watch for sheltered northern areas where this layer may still exist.
Loose dry avalanches running on a crust may travel surprisingly far if snow amounts are as forecast.
Nothing new observed in the past 24hrs.
Expect windslabs along ridgelines on all aspects. Where the new windslabs are overlying a temperature crust from last week be sure to carefully evaluable to the bond with the underlying layers. On northern aspects the interface will be more of a storm snow interface down 20-40cm. With the new snow arriving Saturday evening be sure to evaluate the bond with the underlying snow surface. Where the new snow is overlying a thick MFC it will likely be more reactive so keep this in the forefront of your mind. Windslabs developed during this week will also be harder to locate so ensure you are feeling/evaluating these weakness as you travel.
The storm forecat for today has been pushed back to tonight with 10-15cm forecast with light winds. By 9am Sunday the storm will be wrapping up with skies clearing, and temps around -3. The freezing level is forecast to be around 1800m.
