EF0 tornado, Luttrell to Northpoint, Tennessee, May 30, 2025

From Luttrell to Northpoint, this EF0 tornado ran 2.5 miles across Loudon and Monroe counties on May 30, 2025, touching down at 8:36 AM EDT and reaching 200 yards wide. It killed nobody and injured 5, and did $150,000 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 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

6 damage points were recorded along this path by NWS MRX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 85 mph.

  • Trees and large branches snapped
  • A couple of trees /branches broken. Minor damage to barn garage door nearby.
  • Injury occurred here in the camper. Other barn roof damage at this aid farm.
  • Tree damage (2 different rows). Likely RFD winds leading into tornadogenesis.

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

What the Weather Service recorded

A shortwave trough pushing a weak cold front through the area served as the forcing for this event. The only severe weather observed was a brief EF-0 tornado accompanied by severe rear-flank downdraft winds that injured several residents. This event was unusual: while effective shear was strong at 40 to 50 knots, CAPE was very limited at less than 500J total, and lapse rates were really weak below 6C from the surface upwards. The parent thunderstorm was only broadly and very weakly rotating at time of tornadogenesis.

An EF0 tornado touched down in southern Loudon County in the early morning hours with max winds of 85 mph. Tornado was in Loudon County for roughly 1 mile before exiting into northern Monroe County east of Holt Road. Several injuries occurred when either the tornado itself or the rear flank downdraft winds rolled a camper RV several times up and over a wooden service post. In addition to the RV on the south side of the damage swath, several trees suffered damage, there was roof damage to small structures and a barn, and the tornado left cycloidal markings in the field beyond the RV and houses. When the tornado reached the tree line at the edge of Loudon, several trees had large branches broken off.

An EF0 tornado entered Monroe County from Loudon County and remained on the ground for approximately another mile through northern portions of Monroe County, inflicting minor roof damage to several farm buildings, minor tree damage, and causing additional injuries upon rolling a second RV camper vehicle. The tornado eventually crossed New Hope Road and dissipated shortly thereafter.

The warnings

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

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 Marginal Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 06:00 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.
