The rating scale

Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. EF065 to 85 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. EF186 to 110 mphthis tornado

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. EF2111 to 135 mph

    Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

  4. EF3136 to 165 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. EF4166 to 200 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. EF5over 200 mph

    Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

  7. Unrated

    The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

The damage survey

14 damage points were recorded along this path by NWS PHI, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 87 mph.

  • Tree uprooted and fallen on house
  • shed was blown apart into neighboors yard

What the Weather Service recorded

Multiple clusters of showers and thunderstorms tracked through the mid-Atlantic during the night of June 8 into the early morning of June 9. A warm front was located over the region, with a warm and moist environment present along and south of the front. Moderate wind shear was present, locally enhanced near the frontal boundary. Despite the unfavorable diurnal timing, the shear combined with a small amount of instability allowed for some strong to severe storms developed. These storms produced localized wind damage over New Jersey, along with a brief tornado, as well as heavy rainfall. Storms moved offshore within a couple hours after dawn, and much quieter weather followed behind them.

The tornado touched down near Erial Road just on the other side |of the Marksmen Landscaping company. The tornado traveled |northeast towards the Deer Park Subdivision where several large |limbs were snapped off of both softwood and hardwood trees, with |at least 3 trees uprooted. In particular, damage began on the|southwest side of Deer Park Circle where several tree limbs were |noted snapped off of hardwood trees just on the other side of the |property line. The tornado then moved northeast, almost parallel |to Deer Park Circle where a hardwood tree was uprooted and fell |on the fence line. Multiple large tree limbs were then snapped at |multiple properties up towards the northeast extent of Deer Park |Circle. Debris was also noted on either side of the road in both |directions. One home had soffit removed from the side facing |northeast. At a single family residence at the end of Deer Park |Circle, two large soft wood trees were uprooted with one tree |having to be removed off of a single family residence. ||The tornado then continued northeast towards high tension |powerlines were it began to quickly dissipate. Several branches |were noted just on the other side of the power lines with PSE&G |Utility trucks removing debris from the clearing. The survey team |then looked on Hidden Drive for any more damage, but only debris |made up of large sticks and leaves was noted. No additional damage|was noted on Hidden Dr or any areas north and east of Hidden Drive |Given that several large trees were uprooted, the estimated peak |wind speed was set at 90 MPH, with the tornado being rated at an |EF-1.

What this means

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
