Route Planning
If the forecast does not appear accurate, first verify the route’s Departure Time is correct (shown near the top-left of the chart). Weather data along the route are based on when you’re expected to be at that area (Departure Time + Drive time + Layovers you’ve set). If the forecast does not appear accurate, please contact us so we can look into it further: map’s More icon > Contact Support (on Mac, the Help menu).
