My guess is an ef3

 That’s My guess too by looking at the video footage with the extent of home damages there.

It will be interesting too see what EF rating will be given after being inspected by NWS.

Saw speculation last night of high end EF3 or low end EF4.

Amazing, plus a wedge tornado.

I assume these will be more frequent around here. 

Still that's incredible to see in NJ of all places.

traffic was a nightmare this morning leaving work what should be a 5-10 minute drive home, took me over an hour and 30 mins to get home.

imagine if this hit full force at 3pm yesterday--would have been gridlock and 10x the amount of abandoned/flooded cars

Just took a drive through my town and there are abandoned cars all over the place, roads washed out, and debris all over the place.

All the alerts probably confused some people. Tornado warning, go to the basement...Flash Flood warning, get to higher ground...

That is a great point.  We just don't have experience with these situations around here esp. tornados.

Have there been F4 in CT and MA? I wonder how they occurred so far north?

Yes the flash flood warning and the emergency is very confusing to most people

Here's what confuses me.....the differences between the old Fujita and scale and the new "enhanced" Fujita scale.  And from the mets I have talked to they either don't understand my question or don't understand why it was done this way either.

Here's the basic question....

Instead of making an entirely new scale, why didn't they just adjust the mph ranges of the original scale?  Why have old tornadoes on an outdated scale and new tornadoes on a different scale?  If the original scale was modified with the new ranges wouldn't it be much better namely have all tornadoes, new and old, on the same scale?

I still cannot get over the tornado in Gloucester County, NJ. Yes, we know that we can get tornadoes in NJ and NY but they are never this violent, this long tracked or as wide. 

Ironic for the SNJ branch of our family.  They lived in "real" tornado country (Decatur, IL) for 5 years before moving to Gloucester County in 2015, about 6 miles from the tornado.  They had a baby spinner a few miles from the DEC house, but now an EF3 (my guess) far closer than any major tornados to their old place.

Edit: It was 5 miles away or a bit less.

In 1953 Worcester was hit by an F5 tornado

I don't believe it was ever an official F-5. I think it was high end F-4. I think there has been debate and it was considered and reevaluated but was left as a high end F-4. 

 

Unbelievable what NYC has been going through. Breaking the 1 hour rainfall record at Central Park, and then shortly after shattering the new record. Damn!

[Stormlover74]

Not the Mullica hill tornado

Thanks, apparently there was a strong case to be made that F5 damage occurred around the Assumption College area.

Wow.  My folks are about 5 miles from there.   An area about 20 miles east of there was hit by the late July outbreak too.

I think this would be the second EF3 of the summer (the first one was also in the Philly area.)

Was that the one that caused the first EF3 of the summer?  It ripped up a Home Depot and mall.

yep-I was down there last month-it was near the turnpike and hit a car dealership and some other buildings.   More of a commercial area.  Not sure if there was a Home depot/mall

all the abandoned cars i'm seeing means lots of people went out driving despite the warnings

You can't reason with some people.  I don't understand why you would even want to be out in such miserable conditions.  I left work and arrived home before things went downhill but if I had stayed late, I probably would have just sucked it up and stayed there for the night.  I always keep snacks in my desk and I could have just fooled around on the internet or my phone to pass the time.  Better than venturing into a storm after dark.

The EF4 decision was based on the assumption (no pun intended) that the houses on Uncatena Avenue were of substandard construction.  It looked like classic "5" destruction there - slab foundations swept clean and debris so scattered and reduced as to make it impossible to know from which houses it came, or if it even came from houses rather than a lumber yard.  The massive masonry walls of a large building on that college campus were crushed in by the wind, and I've not seen such damage elsewhere from anything less than a 5.

1953 Worcester tornado was rated F4 under the old rating system.

Either way, it was a hugely anomalous event. The only EF5 tornado ever recorded in the Northeast was the 1985 Wheatland - Hermitage tornado in far western PA. No EF-4 has ever been recorded in the vicinity of Philadelphia.

The July EF-3 hit the Trevose section of Bensalem Township. The F3 damage occurred at a car dealership & neighboring mobile home park. This is the strongest tornado on record to hit Bucks County.

Yesterday Bristol was hit by confirmed tornado that originated in S. Jersey.
