Eager to learn about the possible tornado near Oxford. My dad said it came within a couple of miles of the homestead. They are still without grid power but thankfully they installed a whole-house genny after Sandy and it appears to be working just fine.

Yeah I'm trying to capture their assessments - they just posted another in Bucks (still getting strength assessment) -

They did post a 5:45 pm PNS with what they have confirmed as tornadoes and the one in Oxford was confirmed as one but is still being evaluated like the Mullica Hill & Upper Makefield ones (to get the scale) -

IMO 99% chance it will be retired.

Back in my early 20's I was renting a place w/a buddy in Limerick. Forget what storm but the basement was a disaster w/flooding. Call the Fire dept and they pumped it out for free...I was surprised. So if your basement is a mess w/flooding may want to try that route. (or local fire depts) Some may do it, some may not. Nothing to lose besides them telling you to F-off....

 

 

I called last year during Isaias. The guy on the phone said they don't do that anymore, it's a liability issue. I said, "YOU'RE WHOLE F#%&IN' JOB IS A LIABILITY ISSUE!"

NWS in Mount Holly has confirmed EF-3 for the Mullica Hill tornado.

The flooded water in Philly is just flat out crappy sewage water. Not even sure how fish live in that environment?  Myself, I'd rather smell gasoline if it wasn't toxic.

I grew up/ lived in this area (PA/Del/NJ) for 50 years and the tornadic activity this year has been by far the worse...not even close.  

 

Some gasolines smell better than others, but yeah, in small doses. Sharpies are nice too.

Final rain total here was 4.1".  Enjoying the sudden fall weather!

[Hurricane Agnes]

Mt. Holly tweeted the Oxford results (full report still being done) as EF1 -

 

[mattinpa]

Now 7 confirmed tornadoes. I feel the NWS did a great job. While outbreaks like this are rare in our area, the tornado risk was talked about as much higher than normal. And they nailed the heavy rains. The emergency alerts also likely saved lives. I had 5 alerts on my phone, all flood warnings. But each time I checked in case of a tornado coming.

It's a stone cold lock it's being retired on landfall alone. Almost every high end cat 4 landfall is retired. This just put the icing on the cake.

[Newman]

I cant remember a remnant storm that caused so much devastation. Cat 4 (nearly 5) landfall with a trough interaction taking it towards a perfect track ENE into the area. A storm many from Louisiana to New England will never forget

THE TORNADO TOUCHED DOWN NEAR HARRISONVILLE, NJ DOING MOSTLY 
DAMAGE TO TREES AND LIMBS BEFORE STRENGTHENING AND MOVING 
NORTHEAST. AS IT MOVED TO THE NORTHEAST, IT CROSSED INTO THE
CEDAR GROVE AREA PRODUCING MORE SIGNIFICANT DAMAGE TO TREES WITH 
MANY TREES UPROOTED. 

THE TORNADO MOVED INTO THE WILLOW OAKS SUBDIVISION STRENGTHENING 
FURTHER AND PRODUCING SIGNIFICANT DAMAGE TO TREES, AS WELL AS 
SERIOUS STRUCTURAL DAMAGE TO A NUMBER OF HOMES. SEVERAL HOMES HAD
EXTERIOR WALLS COMPLETELY COLLAPSED, A NUMBER OF HOMES LOST ROOFS
AND UPPER STORY WALLS, AND ONE HOME HAD ONLY A FEW INTERIOR WALLS
REMAINING. VEHICLES WERE TOSSED AROUND AND MOVED, AND DAMAGE FROM
FLYING DEBRIS WAS OBSERVED IN SEVERAL SPOTS.

THE TORNADO CONTINUED TO MOVE TO THE NORTHEAST TO BRIDGETON PIKE 
WHERE MULTIPLE TREES HAD TRUNKS SNAPPED AND MOST OF THE BARNS AND
STORAGE BUILDINGS AT A LARGE COMMERCIAL FARM WERE COMPLETELY 
DESTROYED. THE TORNADO ALSO REACHED ITS MAXIMUM WIDTH AT THIS 
LOCATION AND WAS ESTIMATED TO BE AROUND 400 YARDS WIDE.

THE TORNADO THEN CONTINUED NORTHEAST THROUGH THE WOODS WITH 
MULTIPLE TREES SNAPPED BEFORE ENTERING THE SUBDIVISION AT 
SALVATORE DRIVE. HERE THE TORNADO'S MOST SIGNIFICANT DAMAGE WAS 
OBSERVED WITH ONE HOME COMPLETELY DESTROYED WITH NO INTERIOR OR 
EXTERIOR WALLS STANDING. OTHER HOMES IN THE SUBDIVISION HAD 
EXTERIOR WALLS COLLAPSED ALONG WITH GARAGE COLLAPSES AND VEHICLES
BEING TOSSED AROUND BY THE TORNADIC WINDS. 

THE TORNADO CONTINUED TO THE NORTHEAST DAMAGING TREES AND 
STRUCTURES ALONG ITS PATH BEFORE REACHING A LARGE COMMERCIAL
DAIRY FARM WHERE EXTENSIVE DAMAGE OCCURRED. BARNS WERE DESTROYED 
AND TWO LARGE GRAIN SILOS WERE TOPPLED. THE TORNADO THEN CROSSED 
JEFFERSON ROAD AND CROSSED EACHUS ROAD SNAPPING MULTIPLE TREES. 
THEREAFTER, THE TORNADO MOVED INTO THE BREAKNECK ROAD AREA 
PRODUCING COMPLETE DEFORESTATION WITH NEARLY 100 PERCENT OF THE 
TREES IN A THICKLY WOODED AREA SNAPPED. 

THE TORNADO PATH CROSSED MAIN ST, JUST SOUTH OF CHESTNUT BRANCH 
PARK IN MANTUA TOWNSHIP SNAPPING AND UPROOTING A NUMBER OF TREES 
BEFORE REACHING THE DELAWARE VALLEY FLORIST COMMERCIAL GREENHOUSE
MOSTLY DESTROYING THE STRUCTURE. THE TORNADO DAMAGE PATH THEN 
CONTINUED TO THE NORTHEAST REACHING WENONAH, SNAPPING AND 
UPROOTING A NUMBER OF TREES, A FEW HOMES LOST ROOFS AND ONE 
STRUCTURE COLLAPSED. 

LESS SEVERE TREE DAMAGE PERSISTED TO THE NORTHEAST ALONG THE 
TORNADO'S PATH TOWARD DEPTFORD WHERE THE TORNADO LIFTED. 

THE NATIONAL WEATHER SERVICE IN MOUNT HOLLY WOULD ALSO LIKE TO 
THANK LOCAL ENFORCEMENT AND EMERGENCY MANAGEMENT FOR THEIR 
ASSISTANCE IN THE STORM SURVEY.

A SEMI-DISCRETE SUPERCELL THUNDERSTORM BEGAN TO EXHIBIT ROTATION 
OVER DELAWARE COUNTY, PA AROUND 5:15 PM ON SEPTEMBER 1. THE ROTATION 
CONTINUED NORTH-NORTHEAST INTO MONTGOMERY COUNTY, AND EVENTUALLY 
STRENGTHENED ENOUGH TO PRODUCE A TORNADO. MINOR TREE DAMAGE WAS 
FIRST OBSERVED ALONG STENTON AVE IN FORT WASHINGTON IN THE AREA OF 
THE PHILADELPHIA CRICKET CLUB. A PATH OF TREE DAMAGE WAS OBSERVED 
HEADING NORTHEAST ALONG JOSHUA RD AND THROUGH FORT WASHINGTON STATE 
PARK. SOME MINOR SHINGLE AND SIDING DAMAGE TO HOUSES WAS ALSO SEEN. 

DAMAGE BECAME MORE SEVERE AFTER THE TORNADO CROSSED THE PENNSYLVANIA
TURNPIKE. AT THIS TIME THE TORNADO ALSO MOVED INTO A MORE RESIDENTIAL 
AREA. DAMAGE WAS OBSERVED ALONG MONTGOMERY AVE, SPRING AVE, AND 
PROSPECT AVE AND NUMEROUS CROSSING STREETS OF THOSE. THIS MAINLY 
CONSISTED OF NUMEROUS SNAPPED AND UPROOTED TREES WITH MINOR TO 
MODERATE ROOFING AND SIDING DAMAGE TO A NUMBER OF HOMES. THE WORST 
DAMAGE WAS OBSERVED SLIGHTLY FARTHER NORTHEAST IN THE AREA OF STUART 
CREEK IN UPPER DUBLIN. A NUMBER OF HOMES SUFFERED PARTIAL TO NEAR 
TOTAL LOSS OF ROOFING WITH MANY DAMAGED TO THE POINT OF BEING
UNINHABITABLE. AT LEAST ONE HOME EXPERIENCED PARTIAL COLLAPSE OF 
EXTERIOR WALLS CONSISTENT WITH EF2 TORNADO DAMAGE. NEARLY ALL TREES 
WERE SNAPPED OR HEAVILY DAMAGED IN THIS AREA AS WELL. 

DAMAGE CONTINUED ALONG ROUTE 309 TO THE AREA OF UPPER DUBLIN HIGH 
SCHOOL. THE HIGH SCHOOL ITSELF SUFFERED ROOFING DAMAGE, AND 
SIGNIFICANT ROOFING LOSS OCCURRED TO AN UPPER DUBLIN TOWNSHIP 
BUILDING ADJACENT TO THE HIGH SCHOOL. A NUMBER OF RESIDENCES ALONG 
LOCH ALSH AVE AND SEVERAL SURROUNDING STREETS WERE ALSO DAMAGED. A 
WOMAN WAS KILLED WHEN A TREE FELL ON HER HOME ON KENYON DR, THE ONLY
KNOWN TORNADO-RELATED FATALITY FROM THIS TORNADO OR ANY TORNADO DURING 
THIS REGIONAL OUTBREAK.

FURTHER NORTHEAST, DAMAGE OCCURRED ON AND AROUND THE TEMPLE 
UNIVERSITY AMBLER CAMPUS, AGAIN CONSISTING OF CONSIDERABLE TREE 
DAMAGE AND PARTIAL ROOFING LOSS ON A NUMBER OF HOMES AND UNIVERSITY 
BUILDINGS. THE TORNADO THEN MOVED INTO MAPLE GLEN, CROSSING A 
HEAVILY DEVELOPED AREA NEAR NORRISTOWN RD AT LIMERICK PIKE. SNAPPED 
TREES AND MOSTLY MINOR ROOFING AND SIDING DAMAGE TO SEVERAL 
COMMERCIAL BUILDINGS WAS OBSERVED IN THIS AREA. THE TORNADO REMAINED 
CONTINUOUS BUT DID BEGIN TO LOSE SOME INTENSITY AS IT MOVED INTO 
HORSHAM TWP, TRAVELING EAST OF LIMERICK PIKE. A NUMBER OF TREES WERE 
SNAPPED ALONG BABYLON RD. NEAR HORSHAM RD, ROOFING DAMAGE OCCURRED 
TO A VETERINARY HOSPITAL, ALONG WITH ADDITIONAL LARGE TREES SNAPPED.
DAMAGE APPEARED TO END NOT LONG AFTER THAT POINT. THE TORNADO CROSSED 
HORSHAM RD, BUT LITTLE TO NO DAMAGE WAS OBSERVED IN A COUPLE OF PARKS
ACROSS THE ROAD, APPROACHING THE BUCKS COUNTY LINE. THE TORNADO IS 
BELIEVED TO HAVE LIFTED IN THAT AREA.

THE NATIONAL WEATHER SERVICE IN MOUNT HOLLY WOULD LIKE TO THANK THE 
MONTGOMERY COUNTY DEPARTMENT OF PUBLIC SAFETY AND THE UPPER DUBLIN 
TOWNSHIP POLICE AND FIRE DEPARTMENTS FOR THEIR ASSISTANCE IN THIS 
SURVEY.

THE STORM WHICH PRODUCED A STRONG TORNADO IN MONTGOMERY COUNTY, PA, 
CYCLED AND PRODUCED ANOTHER TORNADO IN BUCKS COUNTY, PA. DAMAGE 
BEGAN NEAR IN THE AREA OF NESHAMINY CREEK BETWEEN VALLEY RD AND 
PEBBLE HILL RD IN DOYLESTOWN. THE TORNADO TRACKED NORTH-NORTHEAST 
FROM THERE, PRODUCING A CONSISTENT PATH OF DAMAGE. DAMAGE WAS MAINLY 
CONFINED TO TREES AND WAS FAIRLY EXTENSIVE AT TIMES, WITH MUCH OF 
THE PATH LENGTH BEING HEAVILY WOODED. NUMEROUS HARDWOOD AND SOFTWOOD 
TREES WERE SNAPPED AND UPROOTED ALONG THE PATH. DAMAGE WAS STRONGLY 
SUGGESTIVE OF TORNADIC WINDS, AND A TORNADO DEBRIS SIGNATURE WAS 
ALSO EVIDENT ON RADAR. THE HEAVIEST DAMAGE OCCURRED NEAR AND ALONG A 
STRETCH OF EDISON-FURLONG RD. EXTENSIVE TREE DAMAGE OCCURRED ALONG 
THAT ROAD AND A NUMBER OF ITS CROSS STREETS. SEVERAL UTILITY POLES 
WERE SNAPPED IN THIS AREA. TREE DAMAGE ALONG NEARBY SWAMP RD WAS 
ALSO SIGNIFICANT. THE TORNADO CONTINUED BUT BEGAN TO LOSE INTENSITY 
AS IT APPROACHED ROUTE 202, WITH SPORADIC TREE DAMAGE OBSERVED ON 
MILL RD. GRADUAL WEAKENING CONTINUED AND THE TORNADO APPEARED TO 
LIFT ENTIRELY IN THE AREA OF BURNT HOUSE HILL RD. THE EXTENT OF TREE 
DAMAGE SUGGESTED MAXIMUM WINDS OF AROUND 100 MPH. NO INJURIES WERE 
REPORTED AS A RESULT OF THIS TORNADO.

A TORNADO EMBEDDED WITHIN A SQUALL LINE DEVELOPED SEVERAL MILES 
SOUTHEAST OF THE STORM WHICH PRODUCED A TORNADO IN BUCKINGHAM 
TOWNSHIP. TORNADIC DAMAGE WAS FIRST OBSERVED IN THE VICINITY OF 
STONEYBROOK RD AT EAGLE RD, NEAR JERICHO CREEK. THE TORNADO TRACKED 
NORTHEASTWARD FROM THERE. IT PASSED OVER THE JERICHO NATIONAL GOLF 
CLUB, AND SPORADIC TREE DAMAGE MAINLY CONSISTING OF UPROOTS AND 
LARGE LIMBS SNAPPED WAS OBSERVED IN A PATH THROUGHOUT THE GOLF 
COURSE. IT THEN MOVED OVER THE ADJACENT BROWNSBURG PARK, WHERE 
ADDITIONAL TREE DAMAGE WAS OBSERVED AND SEVERAL SOCCER GOALS WERE 
OBSERVED FLIPPED IN VARIOUS DIRECTIONS. THE TORNADO THEN BEGAN TO 
APPROACH THE DELAWARE RIVER. SOME MINOR TREE DAMAGE WAS OBSERVED 
ALONG RIVER RD. HOWEVER, THE TORNADO APPEARED TO LIFT JUST SLIGHTLY 
BEFORE REACHING THE DELAWARE RIVER, WITH NO APPARENT DAMAGE ON 
PEBBLETOWN RD JUST PRIOR TO THE RIVER. THROUGHOUT ITS PATH, THE TREE 
DAMAGE PRODUCED BY THIS TORNADO WAS FAIRLY SPORADIC, AND IT MAY HAVE 
BEEN DISCONTINUOUS. NOTICEABLE WIND DAMAGE WAS ALSO OBSERVED FOR AT 
LEAST A MILE EAST OF THE TORNADO TRACK, ESPECIALLY NEAR ITS ENDPOINT 
CLOSE TO THE DELAWARE RIVER. THIS IS BELIEVED TO BE STRAIGHT LINE 
WIND DAMAGE, WHICH IS CORROBORATED BY RADAR DATA, OCCURRING AROUND 
THE REAR FLANK DOWNDRAFT REGION OF THE TORNADIC CIRCULATION. 
HOWEVER, THE EXACT LENGTH AND WIDTH OF THE TORNADIC CIRCULATION IS 
SOMEWHAT UNCERTAIN DUE TO THE SURROUNDING AREAS OF STRAIGHT LINE 
WIND DAMAGE.

Ida sparked memories of Camille, a more intense but smaller hurricane, and the only other one that I can recall that caused significant fatalities both in a GOM landfall and in the Northeast (if one allows VA to be "Northeast").  Both at landfall and especially in the Northeast, Ida's heavy impact was many times greater in area than that of Camille.

I saw this tweet with a video of the 3 days/nights journey of Ida -

Well my namesake Hurricane Agnes did some major flooding damage and has been referenced a lot in comparison to Ida -

It also came up through the GOM but then exited into the Atlantic, regenerated itself, and pivoted around and slammed right into NY.  It was a big rainmaker and a bare Cat 1 at initial landfall and never regained hurricane strength.  It ended up reportedly with 128 fatalities throughout much of its land track (I think PA having the bulk of them).

Similar area of huge RA though SW by 100+ miles, so a solid resemblance in the Northeast, but without the Gulf hit and IIRC Agnes never got beyond Cat 1 (like most June 'canes).

It did hit Florida from the GOM side with its first landfall - and pummeled it with tornadoes, but was definitely much weaker than Ida in terms of winds (bare Cat 1 at initial landfall vs Ida's Cat 4 at landfall).

 

There's a recent article a few months ago looking back at Agnes - https://www.pottsmerc.com/news/local/hurricane-agnes-first-storm-of-1972-packed-a-punch/article_77186288-d531-11eb-bc1c-b300b24bd5f9.html

I used to have a co-worker who was born and raised and lived up in the Wilkes-Barre, PA area and after Agnes hit there, he said his parents' home was completely destroyed and he and they ended up moving down here to Philly.  His parents eventually retired and became snowbirds, getting into a camper and heading down to Florida every October and returning every April (my co-worker would share the driving of them down there and fly back home ).

I just found someone's Super 8 video of the aftermath of Agnes in the Wilkes-Barre area -

It did hit Florida from the GOM side with its first landfall - and pummeled it with tornadoes, but was definitely much weaker than Ida in terms of winds (bare Cat 1 at initial landfall vs Ida's Cat 4 at landfall).

 

There's a recent article a few months ago looking back at Agnes - https://www.pottsmerc.com/news/local/hurricane-agnes-first-storm-of-1972-packed-a-punch/article_77186288-d531-11eb-bc1c-b300b24bd5f9.html

I used to have a co-worker who was born and raised and lived up in the Wilkes-Barre, PA area and after Agnes hit there, he said his parents' home was completely destroyed and he and they ended up moving down here to Philly.  His parents eventually retired and became snowbirds, getting into a camper and heading down to Florida every October and returning every April (my co-worker would share the driving of them down there and fly back home ).

I just found someone's Super 8 video of the aftermath of Agnes in the Wilkes-Barre area -

 

I'd long forgotten Agnes had made landfall in the FL panhandle.  What I do recall is that NNJ had dire forecasts for heavy rain feeding already bankfull rivers but we were sort of the hole in the donut, got less than 2" but had low-end trop storm gusts.  The heavier rain was north, south, and especially west of us.

That was a truly bizarre storm because it was pretty much left for dead and then regenerated itself as it exited into the Atlantic and then did a left turn right back onto land.  But being where it was out in the Atlantic it pushed water into the coast and pumped moisture inland,  swamping everything - essentially like a nor'easter that inevitably causes the rivers to flood. Once that happened, it was game over for so many communities, especially since PA is full of rivers and creeks. 

Thankfully there has been quite a lot of work done over the years to bolster the various watersheds to better handle the water.
