In sintesi

A good freeze is forecast for most areas Sunday morning. We should see sunny breaks, light Northerly winds, and slight afternoon convection with trace amounts of snow. Local hazard depends on how much of a crust forms overnight. SH

    Wind slabs up to 30cm thick sit on sun crusts on solar asp. or temperature crusts on shady asp. These wind slabs were less reactive today as the bond to the sliding surface improves, but be cautious of steep unsupported terrain near ridge crests.

    The sun will poke out tomorrow in some areas, and with it will come afternoon rising hazard on solar aspects. The rate of this will depend on the overnight freeze and amount of solar input locally.

    Activity on the deep, basal depth hoar has tapered off, and we haven't seen a slide occurring on the Valentines surface hoar in quite some time. These layers could be awoken from thin spots, or from a large trigger such as a cornice failure.
