re: What's the end game for hurricane tracking/projections?

I'm certainly no weather expert but from just reading the threads here and watching the news it seems like every time a storm deviates from it's projection they can say why after the fact (dry air, warm water, etc). At some point I'd think we'd have enough data/experience/computing power to predict these things at a much higher rate. Or do we just have that little understanding of how all these work together?
