A meaningful thunderstorm risk is indicated from early morning into the evening. Avoid committing to exposed ridges if storms begin to build. High spate risk based on forecast rainfall. Burns and unbridged crossings may become difficult or impassable. Most likely from around 00:00 until around 00:00 the following day. Cloud base around 400–700 m in the morning, then around 600–900 m around midday and 400–700 m by late afternoon. Expect the top to stay in cloud for most or all of daylight, with no dependable break. A persistently wet day is possible, with around 10-20 mm indicated; local totals could vary considerably. Cloud base is the least certain part of this - the models are only moderately agreed, so it could sit a couple of hundred metres either way.

Forecast confidence: Summit wind could be roughly 23-58 mph, which changes how difficult exposed walking may feel.

A rough, clagged-in day on Beinn Dearg Mòr: summit wind broadly 10-35 mph, with gusts 40-50 mph during the evening (gale-force winds). The ground is likely to be saturated after recent rain. Expect boggy paths and rapid runoff if more rain arrives. There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Most likely from around 08:00 until around 23:00. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base mostly around 400–700 m through daylight. Expect the top to stay in cloud for most or all of daylight, with no dependable break. Cloud is likely to hang lowest on southwestern slopes; the northeastern side should see somewhat higher bases and better breaks. A persistently wet day is possible, with around 10-20 mm indicated; local totals could vary considerably. Low confidence (Summit wind could be roughly 23-58 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 23 to 58 mph; check again nearer the time.
