Mountain Safety First
Weather in the mountains can change rapidly. WeatherQuick helps you make informed decisions, but always prioritize safety.
The 30/30 Rule
If thunder follows lightning by 30 seconds or less, seek shelter. Stay sheltered for 30 minutes after the last thunder.
Summit by Noon
In summer, aim to be off exposed ridges by noon when afternoon thunderstorms typically develop.
Check Before You Go
Weather can change rapidly in the mountains. Check forecasts morning of, not just the night before.
Know When to Turn Back
If conditions deteriorate, turn around. The mountain will be there another day.
