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.
EF065 to 85 mphthis tornado
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mph
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
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.
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.
EF4166 to 200 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
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.
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
1 damage points were recorded along this path by NWS TBW, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 70 mph.
- Carport completely removed. Half landed across the street and the other half went across the river in Paradise Mobile Home Park.

What the Weather Service recorded
A small shower moved onshore during the evening hours, producing a brief tornado over Ruskin.
A brief and narrow damage track was found by an NWS storm survey crew, with scattered debris indicating an EF-0 tornado with a peak wind speed of 70 MPH. The tornado formed west-southwest of the US Highway 41 bridge that crosses the Little Manatee River in Ruskin, FL. The tornado traveled east northeast and caused EF-0 damage to the Paradise Mobile Home Park. Wind speeds were based on mobile home and tree damage. Damage consisted of mobile home roof damage (including a collapsed car port) along with 4-5 inch snapped oak limb and fence damage. Light weight debris was thrown several hundred feet. Additionally, a shed and large construction dumpster were also moved several feet in a different direction to debris.

The warnings
No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

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.

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.
