As it moved northward, Ida began transitioning to a strong mid-latitude cyclone with pronounced frontal features, but with continued tropical moisture. On a regional level, the remnants of Ida became one of the most severe natural disasters in US history, due to a combination of several tornadoes, some of them strong, as well as catastrophic flooding over a large and densely populated area. The severe weather threat unfolded as the system's developing warm front lifted northward from the Delmarva region into Pennsylvania and New Jersey. South of the warm front, partial clearing and moderate to strong instability developed. Meanwhile, very strong shear and forcing, along with tropical moisture, were present within the warm sector. The result was widespread convection in the form of both supercell and quasi-linear thunderstorms. A number of storms became severe across the region, producing several tornadoes and other instances of wind damage. This continued an exceptionally active stretch of high end severe weather in the region, coming barely a month after the tornado outbreak of July 29. The remnants of Hurricane Ida impacted the mid-Atlantic on September 1, 2021. Event Narrative: 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 spotter in Florence reported a funnel cloud over the Delaware River. The tornado which began in Burlington County, New Jersey crossed the Burlington-Bristol Bridge and moved into Bucks County, Pennsylvania. As the tornado passed through a wooded floodplain along |the banks of the Delaware River, no visible damage was noted |either. The tornado then lifted just before reaching downtown |Bristol, PA, with several trees being snapped along the Bristol |Wharf. 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 Limekiln |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 Limekiln 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.
