In the latest visible shot this really is a beautiful storm. Knowing (approximately) what's going to happen over the next few days I hate appreciating it but I can't help it.

Someone on the north side of the Chesapeake area-MD/DEL/NJ coast is getting a heckuva surf day today.

 

Decent surfing conditions today along the South Shore. A 5-6 foot hurricane swell with light winds.

Wow almost 34 ft near Southern Queens, I wonder why it's less in Southern Nassau?  Was this from a track modeled into Sandy Hook of a 145 mph hurricane?  It would be interesting to see the same track modeled with different intensity hurricanes from 1-4.  Also with the new climate regime of stalling hurricanes I wonder how much worse it would be to have a Cat 3/4 stall right along the coast, similar to what the Dec 1992 noreaster or the Ash Wednesday 1962 storm or what Harvey did or what Florence might do.

I would assume the proximity to another large body of water (Jamaica Bay) would account for the extra surge in Southern Queens. For reference, this was assuming the worst-case scenario track, direction and speed in which a hypothetical hurricane would take up here. The exact factors that make up this scenario were a mid-range Cat 4 hurricane (so I assume around 145 MPH) that was racing NW at 60 MPH (very possible, aka the 1938 one) at normal high tide before making landfall in Monmouth County. I assume a stalling hurricane would enhance the surge, as long as upwelling is not a large issue and the hurricane-force wind field has a huge diameter.

One of the positives of hurricane season. There has been hurricane surf (above 3’) on 16 of the last 17 9/11s. Pretty remarkably consistent for a place that doesn’t average much surf the rest of the year. 

I’m waiting for our local buoys to start showing the mega swell associated with the captured fetch of the last couple days. Some of the buoys down south are seeing swell periods of 16 seconds now which are very rare on the east coast. It’s those very periods and the tremendous energy and speed of those wave trains that will lead to beach washovers and flooding of beach front locations when it arrives. Surf wise today was a blast, tomorrow will be at least double the size and challenging!

^^ It's amazing how much more rain I got here from Floyd than the city got, nearly 10" more! I don't remember the total from Irene but I think it was also considerably more than the 7" on that list.

Ha, I was just thinking the same thing.  I had just moved into my house a few months before.  Massive flooding here. There is a brook that runs through the property.  The runoff from Floyd completly rearranged it, ripping rocks and earth from an old dam and one bank and depositing it downstream.  It was crazy town.  Have t seen it like that since.

Chances are you won't see anything like that again for a long, long time. That was something truly amazing. The rain gauge in Fahnestock St Park recorded over 15" of rain that afternoon and most of the area along the Taconics got 14 or more. I don't remember the numbers down in Poughkeepsie but I want to say it was over 12" especially in the hills just east of town. The only other time I've seen rain anywhere near that heavy was in Cordova AK in July of 1989 when we got 11" in just a few hours in town and near 14" at the top of the mountains right above town. If I never see rainfall rates like these two again it will be ok, the devastation that much water in hilly terrain creates is overwhelming and you're absolutely powerless to do anything other than watch. Seeing 60 foot tall trees getting tossed and splintered like matchsticks and watching cars get picked up and washed into ravines is scary stuff :yikes:

Actually, I was up in vt for Irene.  That was biblical.  We were trapped in the mrv for 3 days before there was any road access into or out of the valley.  The destruction along the mad river was incredible.  We were staying at about 2000’ and so had no clue of the devastation until we ventured out the following morning.

You can still see the scars from that event all over the place. The most obvious is going up Rt 4 east out of Rutland but there are some spots where there are trees stacked like cordwood across creeks but they're 15 feet above the regular water level.
