Conditions are changing. Expect wind slabs in the alpine with the strong SW winds that are forecast for Tuesday.
Pockets of wind slab can be found in lee and cross-loaded terrain. Some of these are very dense, hard slabs. When the winds pick up, expect new slabs to form quickly.
There seems to be lots of variability with this layer. As always, thin areas transitioning to localized wind loaded pockets will be more sensitive.
Tuesday is expected to have a high of -10c with 80km/h SW winds in the alpine. Snow is forecast to start around mid-day on Tuesday and could deliver upwards of 20cm by Thursday.
Several loose dry were observed today in the Black Prince area and started in steep unskiable cliffs.
Winds are expected to increase to 80km/h on Tuesday. Expect wind slabs in the alpine, especially just behind ridge crests and lee features. One concern with this slabbing is that it will sit on top on a 1cm crust that was formed 10 days ago during the warm spell and could release on this crust. Approach the alpine with caution and take the time to dig and look at this bond. The November 5 crust is about 60cm down and is showing faceting around it.
