The water.noaa.gov redesign (the last 2-3 years) is considerably less usable on mobile. The old site was old, sure, but they were too interested in making it look and feel new, that they didn't prioritize the basic functionality.
I'm sure the team is well-intentioned, but it should have been done more thoughtfully.
I’d used it some and liked it, though I hadn’t used it extensively. At the very least, some of the parts that had already come out of it to the main site (like the interactive radar) were very useful and good upgrades.
New doesn't always mean better.
