I used to really like Navmonster and used it all the time. It was great for having all the weather information in one place. I remember missing it when it went away.
Now, though, having gone without it for several years (how many?), I've adopted other routines, and indeed the whole weather information/availability scene has dramatically changed. Lots of places now offer the same level of detail. So now that it's back, I'm having a hard time figuring out what it offers that lots of other places don't.
