NWS MARFC retweeted KYW coverage -

As a comparison - this was a pic of the same location (this is around 30th Street Station) at around 2 am (this is where the Schuylkill Expressway goes under the street level along the river) -

If the level hits the progged 19 ft. that may put the Schuylkill Express way shown above, under water.

I already did not long after midnight.  Literally out within 15 minutes when I did.

Got up at ~4:45 am. 

Being retired = being able to take a nap whenever I want during the day.

This was by far one of the wildest storms I have ever experienced. My town was an absolute disaster at the height of it.

You all looked like you had a rain band just training over that area for hours.

It was kind of like Sandy squeezed into fewer hours.

Jeez, my flooding was so bad it picked up my tractor and drove it through the garage wall into the basement (among other damage).

I saw the pics of the water pouring into the subway stations and over the moving subway cars like waterfalls.

I really don't know what one can do about that happening other than finding some way to "cover" every station stairway, which is impossible.

Saw this on reddit. Between Rt 10 and 896 over Rt 1 just outside of Oxford:

WPC preliminary precipitation totals for 9/1 - 9/2/21 -

[Chadzachadam]

The river made it to my doorstep at the intersection of Ridge and Midvale in East Falls. Stoplight on Kelly is almost fully submerged

[MJO812]

Cranford, NJ is under water

People sitting on their roofs

Ch7 is live  there

Insane flooding there

[ChescoWx]

Rain Total in East Nantmeal via VP2 was 4.60"  - of interest the Tempest was only 3.84 an hour ago and it would now appear they have adjusted it up to 5.81" - I will await the "official" CocoRahs reading when I get home

[Lady Di]

Daughter had to evacuate due to flooding.  Schwenksville PA

There will be tears for lots of folks.  Insane storm.

 

[BBasile]

Before and after of a home in Mullica Hill.  That tornado must have been close to an EF-4, if not full on.   

[Plokoon111]

Croydon PA, on vacation in ocean city md. Our basement flooded along the Neshaminy Creek. My drum set, recording equipment, guitars all ruined. Only Floyd and Irene came up high enough to get in.

Hope you are safe and thanks for checking in. I was lucky. House had no flooding and even though the power went out once and flickered a few more times overnight, I retained power. I saw Collegeville is one of the places with a lot of outages.

Was looking for something else and found this yikes!

I think the first image in the video is the waterfall on the Schuylkill near the Waterworks, the 2nd is that Schuylkill River trail, am guessing  the 3rd was done maybe from a boat going under the main bridges going over the Schuylkill downtown (e.g., Market St., Chestnut St., Walnut St., etc), not sure where the 4th was unless it was somewhere in Manyunk, and the 5th is insane - that is the Vine St. Expressway (I-676) that runs parallel to Vine St. "local", and is beneath the street level (with numbered streets going overhead, which I think are those from 21st down to 6th St - I used to use it eastbound to commute to work every day in the mornings, but never the afternoons) - that was apparently completely flooded.

[The Iceman]

Going to check out the Delaware by Trenton in a hour or so. I'll try and take some pics on top of the levy in Morrisville if they will let me go up there.

That's my photo on the bottom!! My 4 chaser friends and I were posting to Twitter and what not. This neighborhood that got destroyed isn't a trailer park, or low-end socioeconomic area. No, these are massive houses absolutely leveled. I can't describe what I saw yesterday in words, you truly have to see it to believe it. Straight out of Oklahoma

21st St pump broke.  Never seen anything like it.

I tried compressing some of the images, I'll post some of the damage photos I took from Mullica Hill here.

I just found this - the entrance to the Vine St. Expressway at 22nd St. (going eastbound) coming off of both the little ramp from the Ben Franklin Parkway and from I-76 (Schuylkill Expressway) - 

Apparently the "Logan Square" neighborhood that is adjacent to that was flooded, including the brand new Giant Supermarket near there at ~23rd and Cherry St.

You know it's always possible, but you still never think you'd see that kind of tornadic destruction around here.   Roofs torn off, cars flipped, sure....but missing houses?
