In sintesi

We will see some flurries through the weekend with easing winds and freezing levels to 1700m. Conditions are slowly improving as bridging strength increases, but consequences will be high if you trigger a slide on the Valentines surface hoar. SH

    The Valentines surface hoar layer has been less active over the last few days. The lack of activity may give some false security, but as it is now buried 70-100cm deep, any slope which gets triggered will produce large avalanches.

    10-30cm of storm snow has created slabs 20-40cm thick. These will be susceptible to human triggering in the short term, especially in steeper terrain. Warm temperatures have promoted settlement and bonding of these slabs to the surfaces below.
