-
Wind: Strong winds can make climbing dangerous, especially at higher elevations.
To mitigate weather-related risks, climbers should:
-
Check weather forecasts regularly
-
Be prepared to turn back if conditions deteriorate
-
Carry appropriate gear for various weather scenarios
-
Allow for flexibility in climbing schedules when possible
