If the website is updated regularly it is a good tool, especially for you in Canada, because you are able to see the canadian GEM forecast model, that is more likely to be more acurate in Canada than the other global models like the ECMWF or GFS. First, the developer needs to make a single button which brings you back to the current time and location. Ventusky is so close to perfect, but there are two small areas for development. Satellite images often show details of tornado damage, especially from high resolution POES images as seen below. Once a tornado is detected, both radars and satellites are used to track the storm.
