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.

  1. F040 to 72 mph

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

  2. F173 to 112 mphthis tornado

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

  3. F2113 to 157 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. 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.

  5. F4207 to 260 mph

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

  6. 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.

  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.

What the Weather Service recorded

Thunderstorms developed along an occluded frontal bounday by midday June 16. Their intensity was aided by a large cold pocket of air aloft combined with the strong June midday sunshine. As the storms approached the Hudson Valley of eastern New York, some of them became severe. Most of the reports were of hail damage. However, there two confirmed tornado touchdowns as well as one non-tornadic destructive wind report. The first of two tornados in eastern New York touched intermittenly down in the town of Florida, Montgomery County between Klapmeyer and Hartley Roads, to the southwest of Amsterdam. The path of this tornado varied between 50 and 100 yards and was approximately 3 miles long. Numerous trees were downed and there was minor damage to several houses as well as one barns. The tornado vortex then lifted back off the ground but was still visible as a funnel cloud. The vortex touched down again briefly in the town of Amsterdam, near Mcquade Road. This second path was only a quarter mile long and about 50 yards wide. Approximately 10 trees were knocked down and minor damage was reported to two homes. The top wind gusts were estimated to be around 70 mph with this tornado. A second twister, ranked as an F1 with top winds estimated around 100 mph, touched down near Pawling in Dutchess County, very close to the place a tornado had struck just two weeks before. The path of this tornado was 125 yards wide and a mile long. Damage was mostly confined to many downed and twisted trees. One tree did fall onto a garage thereby damaging it. Thunderstorm winds blew two trees down on Ravena Road in the town of Coeyamns, Albany County. Golf ball size hail (1.75 inches in diameter) was reported in Chatham while ping pong size hail (1.5 inches in diameter) was reported in the town of Stockport, Columbia County. One inch hail fell at Hopewell Junction, Dutchess County. There were additional reports of dime size hail in Schenectady, Rennselaer and Greene Counties.

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 16:30 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.
