Points saillants

There was about 10cm over Saturday night- down to about 1800m and rain below that.

There could be the odd pocket of windslab about at the top of the upper elevation range, use some caution around ridgetop.

Below about 1800m expect refrozen snow, not much avalanche potential but slick nasty icy snow. Don't try anything silly, look at what the runout is and adjust your plans if it looks bad.

    Sunday was clear and calm and the snowpack has now had some time to settle. There could still be the odd snowloaded gully near ridgeline, on the slopes lee to the west at the very highest elevations. If you're in that terrain then investigate the snow or go around those features.

    In the mid elevations the steepest sunny terrain could loosen up a bit over Monday, in the terrain with rocks poking out. Go around this if anything starts sluffing.
