Loose Wet avalanches will be possible at all elevations. Look for roller balling or a total loss of cohesion at the surface as key signs hazard is on the up!
None reported in the past 48 hours.
Cold snow remains up high and surfaces elsewhere have a crust on them. Above 1800m, Wind deposits from Saturday nights snow remain in sheltered terrain across the Easterly 1/2. In places, these are up to 30cm deep. Elsewhere, the rain crust from July 15th will still be exposed. At lower elevation bands and under the rain crust the snowpack is very well consolidated & spring like.
NW winds increasing throughout the day to severe gale by the afternoon. No precipitation of note. FAFL up to 2700m.
Crampons and an axe will be required. As some warmth and some sun impact the snowpack this hazard will cease to exist.
