Updated 8 min ago

☁ Summit in cloud: the cloud base is forecast below 799 m for 5 of the next 12 hours, from 08:00. Expect poor visibility on the tops.

Summit conditions at 799 m. Wind is much stronger and it feels far colder than at sea level. Gusts above 40 mph make walking difficult on exposed ridges and above 50 mph dangerous.
