Weather, Terrain Hazards, and Timing
Compare multiple forecasts, note freezing levels, wind directions, and hourly changes. On route, read clouds, feel aspect-driven temperature shifts, and watch for pressure changes. If conditions diverge from the model, adapt quickly and communicate adjustments with your team.
