The rating scale
Tracks are drawn in the color of the rating. The Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.
F040 to 72 mph
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
F173 to 112 mph
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
F2113 to 157 mphthis tornado
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.
F3158 to 206 mph
Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.
F4207 to 260 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
F5261 to 318 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.
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.

What the Weather Service recorded
A strong tornado (F2 on the Fujita Scale) struck extreme northern Manalapan and extreme southwest Marlboro Townships. Four houses had severe roof damage and about a dozen others suffered minor damage. A construction trailer was tossed and two vehicles were overturned. Between 150 and 200 trees were either uprooted or damaged. Tree damage was so extensive that Hawkins Road Park was closed. The area was littered with broken pieces of wood, shingles, gutters and parts of roofs. The tornado's path length was about 1.5 miles and its path width was around 200 feet. No injuries were reported. This was the first strong tornado in New Jersey since August 20, 1999 and the first strong tornado in Monmouth County since October 16, 1955.The tornado first touched down near Arbach Lane in Manalapan Township. It initially was relatively weak (F0) on the Fujita Scale, but intensified into an F1 tornado before it reached Kentucky Court. One property on Kentucky Court lost dozens of trees. The tornado also downed trees on Ivanhoe and Rowena Roads. The tornado reached its maximum strength (F2) as it passed through Debracy Court where the worst damage occurred. Four homes suffered severe roof damage. The roof and second floor of one home had to be completely repaired. The windows of another house all burst. A restored Thunderbird was damaged by flying debris that penetrated the garage door. The house apparently shifted as doors no longer closed. A third home on the block had a picnic table blown into its sunroom along with a piece of the neighbor's fence. Patio furniture was splintered throughout the block. A minivan parked in one driveway, was rolled about 40 feet. The tornado weakened to an F1 after it left Debracy Court. Nevertheless, it tore shingles from a home on Eastwood Boulevard and downed a tree onto a car. A construction trailer on Hawkins Corner Road was blown 50 feet across the street and crushed like an aluminum can. As the tornado crossed into Marlboro Township, it knocked down dozens of trees in Hawkins Road Park. The part was closed because of the uprooted trees. As the tornado exited the park, it weakened to an F0. It still knocked a tree onto a house on MacLeisch Drive and ripped shingles and gutters from homes on Guest and MacLeisch Drives. The tornado lifted as it approached Barclay Brook.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.
The forecast that day
The Storm Prediction Center had this point in a General Thunderstorms Risk. The outlook in force was issued at 19:30 UTC.

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.
