Tropical Depression Isaac:

Thu Aug 30, 2012 12:06 pm

Well, goodbye, Isaac! You have been one trouble storm to follow and I'm sure not only gave myself, but many other headaches along the way. It was good to see so many members and guest on this forum as Isaac approached the Gulf states and glad that so many are able to come to this forum for information with our wonderful pro mets and other great members we have on this board that bring vital information to us all.
I think I am ready to say goodbye to Hurricane Season 2012 and bring on Winter 2012/2013 ...of course, the "peak" of Hurricane season this year hasn't even came by.

Time to get back in college mode. Take care everyone!

I slept sooo good lastnight! Even went to be early for a change since not staying up just about 24/7 watching Isaac! Few more storms out there now, but I think I'll wait till the CONUS is possibly threatend....This was a fun CRAZY storm! .....Praying for LA. Continuosly checking on my family too in Slidell....they have lost their home to all the flooding!
