Hurricane Ida generated a tornado outbreak as it traversed theSoutheastern,Mid-Atlantic, andNortheastern United States. Thirty-six confirmed tornadoes touched down fromMississippi toMassachusetts; one person was killed inUpper Dublin Township, Pennsylvania, and several people were injured inAlabama,New Jersey, andPennsylvania. The most active and destructive part of the outbreak occurred during the afternoon of September 1, when several strong tornadoes struckMaryland, New Jersey, and Pennsylvania, including anEF3 tornado which impactedMullica Hill, New Jersey. The same storm later dropped an EF1 tornado that prompted atornado emergency forBurlington, New Jersey andCroydon, andBristol, Pennsylvania, the first of its kind in the Northeast, as well as the first such alert associated with a tropical cyclone or its remnants.[3] This outbreak severely impactedNew Jersey and thePhiladelphia Metropolitan Area, a region which had been significantly impacted by strong tornadoes fromanother outbreak that occurred just over a month prior, as well as several weak tornadoes from the remnants ofTropical Storm Fred two weeks earlier. Overall, the 36 tornadoes killed one person and injured seven others.
Extratropical cyclone, remnant low, tropical disturbance, or monsoon depressionAt 16:55 UTC on August 29,Hurricane Ida made landfall nearPort Fourchon, Louisiana, with sustained winds of 150 mph (240 km/h) and a central pressure of 930 mbar (27 inHg).[4] Strong low-level shear, daytime boundary heating, and weak inland buoyancy led to an increasing risk for tornadoes across theSoutheastern United States. TheStorm Prediction Center (SPC) issued a slight risk for severe weather for the CentralGulf Coast for three straight days between August 29-31.[5][6][7] Numerous weak tornadoes touched down inMississippi,Louisiana, andAlabama during this time. One EF1 tornado caused considerable damage inSaraland, Alabama on August 30, injuring three people.[8] A small slight risk was also issued in theMid-Atlantic for the SouthernDelmarva Peninsula on August 31, where a confluence zone was expected to have an increasing westerly mid-level flow in response to Ida, although it was not the only influence in this area.[7] Two weak tornadoes occurred inSouthwest Virginia that afternoon.[9]
As Ida became extratropical and moved into theNortheastern United States on September 1, a strengthening low-level jet (LLJ) along and south of a warm front coupled with a very moist atmosphere and sufficient surface heating led to a more substantial risk for tornadoes betweenWashington, D.C., andNew York City and the SPC issued a tornado-driven enhanced risk for severe weather for this region. This included a 10% tornado risk with a 30% damaging wind risk added later on.[10] That afternoon, several supercells formed across theD.C. metropolitan area and quickly became tornadic as they moved northeast. An EF2 tornado struckAnnapolis, Maryland, causing significant structural and tree damage throughout the city.[11] Another EF2 tornado caused severe damage in a residential neighborhood inOxford, Pennsylvania.[12] Later, a large EF2 tornado struckUpper Dublin Township, Pennsylvania, severely damaging buildings, homes, and trees, killing one person and causing a few minor injuries.[12] An intense EF3 wedge tornado destroyed several homes and a dairy farm inMullica Hill, New Jersey as well, injuring two people.[12] An EF1 tornado produced by the same storm prompted the issuance of the first evertornado emergency the Northeast, as well as the first such alert associated with a tropical cyclone. A few other weak tornadoes also touched down later that evening and into September 2 before the remnants of Ida moved offshore, ending the outbreak.

This intense wedge tornado caused major damage as it paralleledRoute 45 to its west inGloucester County. It first touched down at 6:10 p.m. EDT (22:10 UTC), east-southeast ofHarrisonville, initially causing minor tree damage. Tree damage became more significant as it moved northeast into the eastern side of Cedar Grove, and dozens of trees were downed at EF1 intensity in the small community. The tornado became strong and destructive as it struck the Willow Oaks subdivision at the northeast edge of Cedar Grove, where multiple homes sustained significant structural damage on Marvin Lane. Roofs were ripped off, exterior walls were collapsed, vehicles were moved and damaged, and one home was left with only a few walls left standing, with the damage in this area being rated EF3. The tornado then weakened momentarily as it struck a commercial farm alongRoute 77 at the south edge ofMullica Hill, destroying barns and storage buildings at EF1 to EF2 intensity before strengthening again and moving through a subdivision in the eastern part of town.
The tornado reached its peak intensity of mid-range EF3 at this location as it moved over Salvatore Lane and Clems Run. Several two-story homes sustained total roof and exterior wall loss in this area, and cars were tossed around. One house was completely leveled, though it was not well-anchored and nearby trees did not sustain damage consistent with a tornado stronger than EF3 strength. CrossingUS 322 past Mullica Hill, the tornado maintained its strength as it destroyed barns and silos at a large dairy farm, and completely mowed down a wide swath of large trees as it moved through a wooded area. In the worst affected area, every tree in the direct path was snapped near the base. The tornado then briefly weakened to EF1 intensity before regaining EF2 intensity as it moved intoMantua Township and passed west ofBarnsboro, where many trees were downed, homes sustained roof damage, and a large commercial greenhouse was partially destroyed. Continuing to the northeast, it remained at EF2 strength as it impactedWenonah, where garages were destroyed, a fire station was damaged, and some homes had roofs and exterior walls ripped off.
The tornado then narrowed and gradually weakened, causing mostly minor damage to trees, fences, roofs and siding occurred inWoodbury Heights andDeptford before dissipating at 6:30 p.m. EDT (22:30 UTC). It traveled 12.37 miles (19.91 km) and reached a maximum path width of 400 yards (370 m). Two people were injured. This was the first F3/EF3 rated tornado in the state of New Jersey since 1990, and one of only four ever confirmed in the state.[11][51] Damages exceeded $64 million.[2][51][52]
