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 mphthis tornado
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 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.
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
Tropical Storm Charley moved northeast across the Coastal Plains of Eastern North Carolina during the afternoon hours on August 14th. Onslow county received the most damage, with estimates over 5 million dollars, as winds gusted to near hurricane force toppling trees and power lines with structural damage to homes and businesses. Winds gusted from 60-70 mph across Inland areas near the center of the storm resulting in wind damage to structures, and damage to crops reaching into the millions. Winds gusted from 40 to 50 mph across locations across Eastern North Carolina with minor wind damage reported. Storm surge values were highest along the Onslow County coastline where a 2 to 3 foot surge was estimated, and 8 foot waves caused minor beach erosion along the south facing beaches. Water levels rose up to 2 feet across the lower reaches of the Neuse and the Pamlico Rivers, and across the Outer Banks. Storm total rainfall, estimated between 4 to 6 inches, occurred across a large part of the area resulting in freshwater flooding in 7 counties across the Coastal Plains. Five weak tornadoes were reported across the area associated with Charley with damage reported. The most significant damage related to a tornado occurred along the Outer Banks in Nags Head.
Law enforcement reported several waterspouts, one of which moved onshore as a weak tornado.

The warnings
13 minutes of warning. NWS MHX issued a tornado warning for this county at 19:27 UTC, 13 minutes before the tornado touched down, in force until 20:00 UTC.

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 Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 16:30 UTC.
SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

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.
