  Moderate to strong winds in the few days have created touchy wind slab conditions on lee terrain in the alpine. We expect these slabs to be added to with a forecast of mod to strong SW winds and 10-20 cm tonight.

  At treeline 40-50 cm of settled storm snow sits overtop of the Feb. 14 surface hoar, up to 80 cm in the sunshine region. Even if a feature has avalanched there is likely residual hazard since we haven't seen good cleanouts in what has gone.
