They stupidly built Armstrong Stadiums with openings on the side. When you have wind driven rain it can rain inside. 

 

I worry about the fans getting in their cars and trying to get home...if they don't cancel the remaining matches..they will be there for 2 or 3 more hours.

November 89 I was in a plane and it’s why I became a meteorologist.  Diverted to ISP after they closed.  I can’t think of any case similar to this here honestly.  Both those events were basically frontal squall lines  

November 1989 was my very first experience with tornado watches and what looked like funnel clouds in the area.  The winds were unbelievable in that event.

NYC CP 1.44" as of 812PM.  G34 kt there too.  3.43" Wantage NJ so we're on the lower side with the max axis developing se of Wantage. Not often that you see virtually all the I95 corridor under FFW's. 815P.

Rainfall thru 815PM... note the 5's in NJ. 

I’m in the 4” bracket in Sullivan, rain intensity (which was never really high all day) is beginning to lighten up a tad, with the back edge quite possibly making it here within the next 6 hours.

[Rjay]

The flooding in NJ is insane.  The flooding prone areas near rivers are going to be a huge problem. 

[gravitylover]

Just passed 2" a little while ago. The rain is now the hardest it has been all day so that number ought to go up pretty quickly. The wind is starting to worry me.

[SleetStormNJ]

This is going to be bad for C/N NJ.

That outbreak produced an f4 in connecticut I believe. I think it also produced the strongest ever tornado on record on long island which was an f2

edit: actually that was July 1989 I was thinking a totally different outbreak that same year

[SnoSki14]

Yeah we'll bust low. It's gonna get ugly.

Ground is completely saturated, water has nowhere else to go.

[Rjay]

Still off and on downpours here 

[Rmine1]

Starting to breathe a little easier here in SW Suffolk.

The warm front's going to pass north of us. Plenty of heavy rain to come but the heaviest will definitely be west/north of us near where the front gets stuck.

Follow HRRR.  You and I are basically done around midnight-2A.  I am thankful it is soon to lessen here. 3.54" climbing. 

[lee59]

Just passed an inch of rain here.

[wdrag]

From Mt Holly... the official unofficial sensor amounts through the 8PM ob, past 24 hours in NJ/PA. 

[RippleEffect]

It’s been a while to see this type of rain!

[nycsnow]

I’m in a severe t storm warning now

[winterwx21]

Haven't seen flooding like this since Floyd.

Theres a line of thunderstorms that look pretty serious in the eastern part of Delaware that look like they’re heading right to our area. Probably a good 4 hours away at least.

Simply unprecedented severe storms/tornadoes and not quite unprecedented rainfall, but looking like as much as Floyd, Irene and what we saw for Henri in spots.  Long night - we have some water entering into our basement through our window well windows (the usual path for us in the worst storms), so not posting much - so far, nothing the French drain can't handle, but if it gets much worse, might need to use the portable sump pump.  Be careful out there.  No more current tornado warnings, which is good - the rain is bad enough...
