I just saw my first advisory scroll on the IS2, a fire weather watch.
The text is much smaller than on any SD Star, but, since it's high definition, it's still easily readable.
The one thing I don't like is that it doesn't replace the LDL, but simply sits on top of it and cuts off the bottom section. (I can see clouds in the extended forecast but I don't know if there's any precipitation falling from them.) As much as I liked the larger LDL from 2 years ago, my one major complaint with it was that advisory scrolls cut off the bottom of those, too.
