EF0 tornado, Gold Hill, North Carolina, February 6, 2020

This EF0 tornado ran 1.5 miles across Rowan County on February 6, 2020, touching down at 11:55 AM EST and reaching 50 yards wide. It killed nobody.

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 mphthis tornado

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

  2. EF186 to 110 mph

    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

36 damage points were recorded along this path by NWS GSP and NWS RAH, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF2. The highest wind the damage implies is 125 mph.

What the Weather Service recorded

Unusually high levels of moisture for early February combined with a slow-moving frontal system to produce an extended period of moderate to heavy rainfall across western North Carolina from the morning of the 5th until the early morning hours of the 7th. Intense rain rates associated with bands of heavy rain showers and embedded thunderstorms developing along the front during the morning and afternoon of the 7th resulted in rather widespread flash flooding. Isolated tornadoes also developed during this time across the Piedmont. Total rainfall of 3 to 6 inches resulted in flooding persisting along some main stem rivers and larger streams well into the 7th.

NWS storm survey found a weak tornado damage path that began near the intersection of Old Beatty Ford Rd and St Stephens Church Rd south of Gold Hill. A small barn was damaged at this location, which was the most significant damage along the track. Some some trees were snapped and uprooted here as well. The tornado snapped and uprooted trees as it moved east along and near Old Beatty Ford Rd before ending near Old Highway 80.

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 Enhanced Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 16:10 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.
