Ohau — Bulletin d'avalanche

27 July - Two loose wet avalanches were observed on north-facing slopes. 26 July - Several size 1 wind slabs were observed or triggered by ohau ski patrol team below ridge crest on E to SE aspects. Rain, heavy at times about the Divide, spreading elsewhere from afternoon. Snow lowering to 1200 metres.wind at topNorthwesterly 70 km/h easing to 40 km/h early evening.freezing levelLowering to 1500 metres evening. Firm snow conditions are present on west-facing slopes near ridgelines and at lower elevations where a rain crust exists. These hard surfaces may present a sliding hazard, particularly on steep terrain and may be cunningly hidden under new snow.

Approximately 15–20 cm of new snow fell between 23–24 July, accompanied by strong northwesterly winds that later shifted southwest. Since the storm, consecutive cold, clear nights have promoted near-surface faceting, preserving dry, and low-density snow. Strong northwesterly and southwesterly winds formed wind slabs on East to South aspects during the storm cycle. These slabs have continued to stabilise and have shown little to no reactivity in recent stability assessments.
