Most of the weatherboard action seems to be at http://www.storm2k.org/ with its tropical forums, but you have to be a registered member (which I am) to get to see the Tropics Talking board (where you can drown in all the data and arguments). Eastern will let guests in to view similar talk, and it is more condensed during the summertime (but during the winter WATCH OUT for the overload during storms!)
By the way, the links at the top of this thread are great and very useful.
Storm2k is good in the summer. We (easternuswx.com) just got going last yr, so we are still building a summer base. Winter is a mess, as our snow lovers outnumber hurricane watchers by a good margin. The meteorologist input on easternuswx.com is easily amongst the best on the net right now.
