You can see on the radar how this setup works-the smaller cells firing up over the ocean and heading NW, then exploding into the firehose when they reach the inverted trough. 

You can also see the flow from the SW into the trough from central NJ.  Very interesting event that is unfolding here.

Water quality in the ocean is going to be terrible the next few days from any junk floating away in the floodwaters. I remember after both Henri and Ida seeing the beaches in NJ littered with trash, clumped up toilet paper and wet wipes, as well as pharmaceuticals too. Not a good time as fishing/surfing is getting good again.

5 towns area/Atlantic Beach getting destroyed. There’ll definitely be 6-8” rain totals in that area. Long Beach to Rockville Centre next up. 

Edit-probably conservative on the rain totals. Already 6” in some of those places.

Been trying to look at that as well.  Let me know if you figure it out first.

I went back in Pivotal wx to 12z Tue PW 1.6" which definitely sagged south and then acquired more PW east of the Carolinas and has since bulged north to LI as of 06z/29 EC op.  EPS ens do not have PW on National scale. 

Reflux works for me  but without the detail needed to confirm via soundings, trajectories. I don't want to upset anyone about this, but points well taken earlier.

 

Looking ahead...I won't reflux what happens Oct 5-8.

As the rainfall graphic below shows, the amount of rain east of the Hudson in NYC/SENY and just off the NJ coast (except some very heavy rains at the immediate coast and just into NJ across from the Hudson) has been incredible, with the following highlights from the story linked below. There will likely be parts of that area that get 7-9" of rain, which is 2 months worth in one day.  

https://www.cnn.com/2023/09/29/weather/new-york-city-northeast-rain-flood-forecast-climate-friday/index.html

• In Brooklyn: A month’s worth of rain, up to 4.5 inches, fell in only 3 hours on Friday morning, according to National Weather Service data. This three-hour rainfall total is only expected about once every 100 years in Brooklyn, according to NOAA estimates.
• In Manhattan: Nearly 2 inches of rain fell in one hour in Central Park, the second-wettest hour there in 80 years. More than 5 inches of rain have fallen there so far.
• In Queens: It’s a top-10 wettest day at John F. Kennedy International Airport, where more than 4 inches of rain has fallen since midnight.

The main firehose band looks to be pivoting east very slowly. Nassau might be screwed pretty soon and my area needs to keep an eye on it too. Already 3-5” in western Nassau. 

I wonder what the 5 towns area looks like.  Holy crap. 

[Cerinthe Major]

Some roads along the shore are closed in Port Washington, and our backyard is completely flooded (luckily it's all still downhill from the house). I'm a bit surprised they haven't canceled afterschool activities. Not looking forward to figuring out a route to pick my kid up!

This is insane and the radar from JFK to Mid nassau is exploding now...

This is the worst freshwater flooding I've ever seen at the beach   this is Wesley Lake in Asbury Park

A friend of mine lives in Woodmere and says his entire neighborhood has 2-3 feet of standing water.

If only it was January.....

Firehose is making some headway east. I might be in for it near the Nassau border.

10.6 for the month as of 9am. Could get to a foot

That certainly would break the September record for rainfall. Current record is 11.85" of rain for the month.

[Allsnow]

Worst of the line moving east out of queens. Unfortunately, central LI will be under the heavy rain

No I believe it's 16"

[Brian5671]

Euro has another 2-3 inches mainly city and east

[Sportybx]

When is this suppose to be officially over ?!? 

[Superstorm93]

Extremely impressive ARI numbers showing up south of JFK

Same areas are 300-400x their FFG at this point

Flooding at New Rochelle High School.

 

 

They got hit pretty bad in Ida too. Was closed for weeks

[Picard]

With all the damn flooding of late, here and elsewhere, I feel like this is going to start taking a tool on the supply of reliable vehicles, as well as vehicle insurance premiums.

[donsutherland1]

JFK Airport has reached 7.26” rainfall today (2nd highest daily rainfall) and 7.88” storm total rainfall (highest two-day rainfall on record).

[uofmiami]

3.08" in Syosset & 2.90" in Muttontown

[jm1220]

This definitely has to be the south shore's Ida, since that area escaped the worst of it then. S Nassau just getting annihilated, and JFK with nearly 8" total.

[Brian5671]

that band over western LI was well modeled yesterday by the long range HRRR
