There is currently a live chat on weather.com to discuss the new layout. It says discuss the "sneak preview" though, so does this mean the site is not permanent yet? From the looks of the posts on the chat, a lot of users do not like the "vertical" layout of the Hourly, 5-Day, and 10-Day forecasts (which I can't blame them for). I, as well as a few others, also miss the "Right Now" page having the current conditions AND the 36-hour forecast. According to TWC, supposedly they are working on a new design for the 10-Day that will bring back the horizontal view.
Oh, and one more thing, why does TWC ALWAYS neglect to re-design the "Monthly" page??? I mean, I guess it's alright that they don't, but I can't even begin to tell you how old that design is.
