Not gonna let you have it but helpt you understand more...

- It has essentially made landfall

Somewhat. Landfall's don't really matter when dealing with non-pure tropical systems as those systems tend to have their strongest surface winds wrapped tightly around the center of ciruclation which is indeed why landfall is important. Read my next answer for this to make sense...

- It's no longer a 'hybrid storm'. It's more like a regular hurricane which has made landfall

It was still fairly semi-tropical with unique interactions with the vorticity max associated with the upper level jet. It was just now in the past 3 hours underoing that "transition" that had been widely recognized as "the hybrid" storm the models indicated. It didn't change as rapidly as we thought... however once it did it was quickly advanced westward and as it did it's inner core is nearly ripped out of a closed circulation as it merges with the vort max associated with the jet. Thus, the storm as we speak and as it makes "the landfall" is underoing that transition that we've heard so much about. With that said now your going to see (all of us) a new interaction of a strenghtening hurricane rapidly transitioning into a extra-tropical type of storm (somehow with a warmcore that will surely be dismantled).

- When hurricanes make landfall, they weaken

True story. However tropical cyclones do not surive the conditions that Sandy did for as long as she did given the conditions in the atmosphere and SST's. Her "Hybrid" characteristics were because she was feeding off of baroclinic energy fed from the upper level jet interaction. Now that it's quickly transitioning we may see some intensification of winds from a different direction and or magnitude as this system reorganizes. Storm surge could be amplified into tonight due to increased mixing of winds down to the surface from SE. Extra-tropical storms do not need oceans to feed off of, however this cummulated energy will make for an interesting evolution of this system over the night and through tomorrow depending on how quickly the system becomes vertically stacked and thus shut's it self down. however storm surge, bad winds the whole thing is not over. We now have a rapidly transitioning system... will be a learning expeirence for sure.

- The eye of the storm is, what, 75 miles away?

I actually don't have answer for this one, lol. Who knows. The eye was being dismantled as it was speeding towards land as it was making that "extra-tropical transition) . Doesn't matter. It's not anywhere near over. Don't be confused :)

Hope that helps.

This was in the Philly obs thread, shared by Quakertown needs Snow from Twitter... another friend of mine says it was taken from the Flagship Resort, Atlantic Ave. and South New Hampshire Ave in Atlantic City.

WOW...that is INSANE

I'm in Bayville on the North Shore if Long Island and the winds have been hustings higher in the past 30 minutes or so then they have all day.

The LI sound looks like an ocean and there was flooding with the high tide this morning. The bridge out/into town has been shut down since then.

We lost power around 2 and got it back around 5.

Sorry for the lack of scientific measurements!
