The real danger is that the Northeast hasn't seen anything more dangerous than "Super Storm" Sandy in a very long time. There is nothing like a hurricane code or one way traffic inland put into law much less practiced at night so the cops and other first responders have the for the emergency. That means even a single Category one hurricane is likely to mismanaged as badly as Puerto Rico was but with higher population density multiplying bad outcomes. The utility vehicles will already be busy in the Carolinas so getting the grid back up will be to some degree amateur hour as well. Short of hoping the models are wrong I don't see much that can go right.
