EF3 tornado, Woodard to Windsor, North Carolina, August 3, 2020

From Woodard to Windsor, this EF3 tornado ran 10.0 miles across Bertie County on August 3, 2020, touching down at 1:15 AM EDT and reaching 600 yards wide. It killed 2 people and injured 14, and did $1.0 million of property damage.

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 mph

    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 mphthis tornado

    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.

What the Weather Service recorded

The center of Tropical Storm Isaias tracked north just inland of the Middle Atlantic Coast from late Monday night, August 3rd through Tuesday morning, August 4th. Outer bands north and east of the Tropical Storm produced three tornadoes across portions of northeast North Carolina.

A damage survey conducted by the NWS Wakefield office found a path of storm damage consistent with an EF3 tornado. The tornado touched down near the intersection of Knowles Lane and Middle Track Road. It then tracked to the north northwest and reached its strongest point just south of the town of Woodard as it crossed Morning Road, where its width increased to just over one third of a mile and it reached EF3 intensity. The tornado completely destroyed several mobile homes and stick built houses in this area. It flattened seven single-wide and double-wide mobile homes, leaving unrecognizable bits of debris. The fatalities and injuries occurred in the vicinity of Morning Road. The tornado weakened to EF1 intensity as it approached the west side of the town of Windsor, but it did damage a farm on Highway 306. The tornado then lifted just before reaching Governors Road about 2 miles northwest of Windsor.

2 direct deaths are recorded for this tornado, each with what Storm Data knows of it.

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 00:59 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.
