Wow, go away for a day and miss everything, lol. Only quickly skimmed the thread and thought I'd add one important point. While there hasn't been a major (cat 3/4/5) hurricane making landfall in the US, while it was still a major hurricane, since 2005, that doesn't mean there haven't been destructive storms during that period.
The most obvious is Sandy, which was the 2nd most powerful tropical system in the modern era (usually defined as the late 60s with the advent of satellites), as measured by integrated kinetic energy, which calculates the cumulative energy of a cyclone across its entire area of impact.
It certainly didn't have anywhere near the strongest winds, but it was friggin' huge, having tropical storm force winds extending nearly 500 miles from its center, which is unheard of. Those winds over a large area over a fairly long period, as it approached the NJ/NY coasts were what made for such an incredible impact, especially with regard to storm surge and inland damage to trees (and the power impact). The graphic, below, shows it well.
One other point: while Sandy was declared to be an extra-tropical system before landfall around AC (having merged to a certain degree with a powerful frontal system, leading to the storm acquiring some "cold core" characteristics, i.e., deriving its energy from temperature gradients across large areas, instead of purely from evaporation of warm ocean waters), that was purely semantics.
Sandy did have cat 1 hurricane force winds at landfall and the NHC never should've allowed those semantics to stop it from issuing hurricane warnings (those rules changed after Sandy, as we saw with Hermine, where TS watches/warnings were still kept in place after it had largely transitioned to being an extratropical system).
By the way, Irene was a Cat 3 major hurricane in the Bahamas, but it weakened to a strong TS by the time it made landfall in Little Egg, NJ and then NYC.
