Hurricane Ida tornado outbreak

At 16:55 UTC on August 29, Hurricane Ida made landfall near Port 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 the Southeastern United States.

[8] A small slight risk was also issued in the Mid-Atlantic for the Southern Delmarva 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.

[12] Later, a large EF2 tornado struck Upper Dublin Township, Pennsylvania, severely damaging buildings, homes, and trees, killing one person and causing a few minor injuries.

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.

The tornado then weakened momentarily as it struck a commercial farm along Route 77 at the south edge of Mullica 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.

Continuing to the northeast, it remained at EF2 strength as it impacted Wenonah, 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 in Woodbury Heights and Deptford before dissipating at 6:30 p.m. EDT (22:30 UTC).
