EF1 tornado, Louisa to Cuckoo, Virginia, May 27, 2022

From Louisa to Cuckoo, this EF1 tornado ran 2.6 miles across Louisa County on May 27, 2022, touching down at 7:51 PM EDT and reaching 450 yards wide. It killed nobody, and did $100,000 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 mphthis tornado

    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

26 damage points were recorded along this path by NWS AKQ, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 95 mph.

  • Hardwood trees uprooted and snapped. Path width roughly 250 yards
  • Numerous large trees uprooted and some snapped. Several outbuildings damaged and destroyed by uprooted and falling trees. The main residence avoided the main impact of the tornado, but did have shingle damage.
  • Large tree uprooted in front of vacant residence. Numerous other trees snapped and uprooted on property.
  • Clear damage path continued south of a residence with hardwood trees uprooted and snapped.

What the Weather Service recorded

Scattered severe thunderstorms in advance of a cold front produced damaging winds and two tornadoes across portions of central Virginia.

The National Weather Service in Wakefield surveyed the storm damage in central Louisa County and found it to be consistent with low-end EF1 damage with peak wind speeds of 90 to 95 mph. The tornado touched down in an open area southwest of Yanceyville Road near Bend of River. Sparse trees were snapped in the area. The tornado then entered a wooded area northeast of Yanceyville Road with a clear path of snapped and uprooted hardwood trees. The path at this point was over 200 yards wide with likely low-end EF1 damage. Next, the tornado moved through an inaccessible area before impacting a home at the end of a long lane. This home had shingle damage, a window broken, a backdoor ripped off, and damage to the chimney. There was also peripheral damage from snapped and uprooted trees, with a clear and consistent path observed through the trees. The tornado continued through the woods and eventually emerged onto Mount Airy Road and the Hunters Landing subdivision. Numerous large hardwood trees were snapped and uprooted. The fallen trees exhibited a clear circulation pattern in this area as the tornado became quite wide, at least 450 yards. This is where the most concentrated damage occurred and was likely low-end EF1. In addition to tree damage, several homes had shingles ripped off, siding removed, awnings and gutters damaged, and broken windows. Additionally, peripheral damage from fallen trees was observed. From this point, the tornado entered a rural area where the forest had been cleared, with no visible damage indicators. The tornado lifted and dissipated in this area before reaching US-33/Jefferson Highway.

The forecast that day

The Storm Prediction Center had this point in a Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 19:44 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.
