A Powerhouse!
Ive used Seasonality Core practically since it debuted. It offers loads of weather information in graphic format and a unique map of the entire world that includes the wind flow, fronts, highs and lows, temperatures, satellite and radar, all in one shot. The developer is working to bring full coverage to more parts of the world. The only frontiers left for expansion seem to be lightning strikes and storm tracking.
