Burns and unbridged crossings on the approach may rise quickly. Allow for changing water levels.
A grey, cloudy day on Sgùrr Dubh Mòr: summit wind broadly 20-35 mph, with gusts 35-45 mph early in the morning (gale-force winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base 500-800 m - expect clag for much of the day, though a brief clearance is possible early in the morning. Cloud will be lowest on the W slopes, down to about 500-800 m; the E side should be clearer, lifting to around 700-1000 m. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. Cold on top: air temperature broadly 2 to 6°C, feeling around -4 to 0°C in the wind - wrap up. Confidence moderate - the forecast models differ somewhat (the forecast models show a moderate spread), so treat the numbers as a guide.
