Yahoo has just released a beautiful weather app for the iPhone (no iPad yet) that blends location based Flickr photos with a clean interface.
I have always been a big weather junkie and probably have way too many apps related to weather. I tend to prefer information over design when it comes to weather apps (sat24 is the one I check first) but I may be clicking on this more.
My only real grip so far is the icon used as it does not do the app justice. But I suppose this is inline with the rest of the yahoo apps in their suite.
