Abstract: A weather forecasting system and method. The system includes a mobile computing device that may request, from a server, real-time weather data at an exact time for a location. The real-time weather data include weather data from up to sixty minutes prior to the exact time. The system can predict future weather data for up to sixty minutes after the exact time. Weather maps of real-time and future weather data can be layered over each other and on selectable background maps such as terrain, roads, etc.

Abstract: Navigation based on a weather forecasting system and method. A weather-based system and method for navigating or routing from an initial destination to a final destination. Routing may involve driving, air travel or the like. The system receives via a mobile computing device, a starting and destination location information and uses recent sequence of periodic real-time weather data for the starting, destination and in-between areas information to determine expected weather movement for the near future for respective areas. Based, in part, on the expected weather movement for the near future, the system determines optimal routing directions from the start to final destination.
