1. A computer implemented method for generating a map for ground navigation comprising a weather forecast, the method comprising:

  • receiving, at a navigation device, a map request indicating a departure location and a destination location;

    in response to receiving said map request, obtaining map data associated with a route between the departure location and the destination location;

    obtaining a plurality of precipitation forecasts, each precipitation forecast indicating a probability of a different one of a plurality of precipitation types occurring at a point along the route at an estimated time of arrival (ETA) associated with the point;

    obtaining a plurality of rate forecasts, each rate forecast indicating a probability of a different one of a plurality of precipitation rates occurring at the point at the ETA;

    combining the plurality of precipitation forecasts and the plurality of rate forecasts to generate a probability distribution indicating probabilities that each of the plurality of precipitation types will occur at each of the plurality of precipitation rates at the point at the ETA; and

    displaying, on a display device of the navigation device, a map of the route and a visual indicator of at least one probability in the distribution.
