As we know, a center over land is not conducive to intensification, and it typically results in weakening. It stands to reason, then, that more time over land will result in more weakening that previously anticipated. We don't really know that much about how quickly storms can/do weaken over land, and it's not THAT far from the water now, so I wouldn't expect it to fall apart completely. Once it gets off the NJ coast, it will no longer have much access to very warm, hurricane-supporting water temperatures; current buoy measurements show water temperatures <25 C from NJ northward.
In addition, I suspect that part of the reason why the response now is different from the response from Gloria is because (a) there are hungry lawyers around, (b) there are other politicians and political groups just waiting to jump on any public official who makes any mistake that results in unnecessary injury, destruction, or death, (c) just because a response happened in the past doesn't mean that it was the best course of action and that it should be repeated exactly next time when a similar-but-different situation occurs. In the realm of public safety, it's almost always better to be safe than sorry. I saw "almost always" because there are times when over-warning or exaggeration of threats can leads to increased complacency and inaction the next time a similar forecast is made if the original event did not live up to expectations (think of the "cry wolf" situation). We hear about over-warning and personal irresponsibility a lot in the more hurricane-prone areas when it comes to the excuses people give for not following safety protocol ("We get these all the time, and it's never this bad. Come emergency rescue me now!").
Definitely can't say this was unexpected. Well within the track uncertainty. Also, Irene is currently tracking over an area over which is shouldn't weaken terribly much due to land interaction. In addition to the sound water, the land in this area is quite swampy. Not ideal, but probably good enough for a Cat 1 to last a little longer than usual. Storms have actually developed in this area (i.e. 1997 Danny).
