Weather Tips for Old Faithful

• Check official access notices, alerts, road or trail conditions, fire restrictions, and local forecasts before leaving.
• Turn around before exposed ridges, canyon rims, or open ground become unsafe in lightning, heat, smoke, high wind, or poor visibility.
• Carry layers, water, navigation, sun protection, and seasonal traction or flotation appropriate to the activity.
• Allow extra time for remote roads, mountain passes, wildlife, spring runoff, wildfire smoke, and limited winter daylight.
