Representing geospatial information
There are a lot of things one could do with that information.

Lat. and long. are the most precise data one can get on location, but that data itself may not say much about anything, really.

When I read this:


  predict the location of a storm at a given time


the first things that come into my mind are: what would define each coordinate point? You could get terrain height, closeness to some geographic accident... Things that would actually impact on the weather, more precisely, storms.

This is all intuitive. I'm not sure this can help in any way, but hopefully, it will at least help to think of something actually useful.
