Mesmerizing. I can see I'll be spending a lot of time looking at this in the winter
I used it while tracking Hurricane Matthew here. Rainfall mouseover is particularly handy.
The first time I looked, either the mouseovers weren't working or I was too distracted by everything else going on. Being partly colorblind, the mouseover is key to figuring out the freezing altitude (and thus a rough idea of where it's snowing).
