A rough, clagged-in day on Beinn Mhic-Mhonaidh: summit wind broadly 25-40 mph, with gusts 45-55 mph around midday (gale-force winds). The ground is likely to be wet after recent rain. 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 18:00.
