Well, I just finished checking out the radar from Daytona, and, while I'm no meteorologist, I think I can confidently make a prediction: You can spend as much time in the bathroom as you want right now.
Which is to say, this thing ain't gettin' underway for awhile.
Best estimates from Daytona are targeting 4:30 or so for the drop of the green, but I think those estimates are wildly optimistic. The radar's showing solid green moving west to east across Florida from well out in the Gulf of Mexico. Wouldn't be surprised if this is a washout.
