Austin's right with the pressure dropping, and winds have stayed steady from the last update. I'm not expecting further strengthening over the short term, primary because it looks like the center of circulation is just about to come ashore. It just looks like a mid-latitude cyclone because of the dry air it is sucking in. Looks like further weakening is the name of the game from here on out. Not to mention excessive rainfall totals.
EDIT: Doppler estimates 8.75 inches of rain have fallen in downtown New Orleans so far. A closer radar located at the airport, I think, puts rain estimates exactly 5 inches higher.
