There’s no end of information around here these days, just a weary librarian trying to pull the best bits out of the pile for you…
Here’s NASA’s great site, with images and animations galore. Latest Storm Images and Maps from NASA.
And, in a nice example of my tax dollars at work, the Virginia Department of Emergency Management has a good set of Gustav-related links here, in their “Situation Reports Archive“. The page is worth a bookmark.
Finally, Google has pulled together a “meta-page” on Gustav, with links to news and Google Earth Weather. Also, all the affected states’ Hurricane Centers or Emergency Management links are listed here.
