Burns and unbridged crossings may rise quickly. Assess them at the water and turn back if unsure.

Cloud-free timing: Around 0% early, improving to around 20% later.

A rough, clagged-in day on Three Pikes: summit wind broadly 10-25 mph, with gusts 25-35 mph during the evening (fresh and blowy). A meaningful thunderstorm risk is indicated from around midday into the evening. Avoid committing to exposed ridges if storms begin to build. There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Most likely from around 00:00 until around 23:00. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base mostly around 500–800 m through daylight. Expect clag for much of the day, though a brief clearance is possible during the evening. Cloud is likely to hang lowest on northwestern slopes; the southeastern 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. Confidence moderate (Summit wind could be roughly 14-25 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 14-25 mph, so treat the headline as mid-range.
