Mountain Conditions
General Conditions:
Saturday 1st August 2020, 07:28hrs: Warm conditions continue; rainfall, so far, has been a non-event, with only light drizzle, cloudiness, and galeforce NW winds for past few days. It would appear a similar weather pattern is likely for the next 5 days - lowest forecast snow is 1600m on Monday. Snowpack is softening in the unseasonally warm temperatures, though surface ice has been reported on northern aspects.

28/07/2020 17:34hrs: Incoming drizzle/rain for several days (variable intensities; greater quantity on Sunday/Monday ), with exceptionally high freezing levels; expect snowpack to slowly load up with moisture, high level snow (1700m+) may find its way downhill in wet sluffs by Monday. There is a impenetrable buried crust in the pack on many aspects reported by several climbers, so slope failures are conceivable later in this storm-cycle.

24/07/2020 07:13hrs: The storm-cycle has past; about 30 - 50cm of fresh snow has fallen at 1800m (10 - 20cm @ 1500m), with wind deposits being much deeper. This fresh, unconsolidated snow is sitting upon icy melt-freeze crusts and could be poorly bonded. Preexisting snowpack was quite variable but hovered around 50 - 100cm at 1800m on the Main Range. Windslab has also formed on lee to northern half aspects. Weather is fine today, however cloud is forecast to thicken from tomorrow (Saturday) about the Alps, fine on Monday, and rain/snow return on Tuesday.

21/07/2020 17:27hrs: After about 40-50mm of rainfall, snowfall levels are now dropping below tree-line (1400m); it has been snowing fairly heavily above 1900m from the beginning of this storm-cycle. Over next two days snow is expected to lower to 400m or less.

19/07/2020 07:25hrs: Warming temperatures today after a week of sub-zeros; cloud, wind, rain (heavy Monday night/Tuesday) and lowering snowfall levels (100m eventually) takes us out to Thursday this week. The snow-pack has been consolidating over the past week with the freeze/thaw cycles; most snow-pack is 1500m+, though shadowed alpine valleys are holding snow at 1100m+.
