EF0 tornado, Bayard, Florida, January 9, 2024

This EF0 tornado ran 0.2 miles across Duval County on January 9, 2024, touching down at 4:08 PM EST and reaching 30 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

1 damage points were recorded along this path by NWS JAX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 74 mph.

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 strong pre-frontal squall line of strong to severe storms moved quickly eastward across SE GA and NE FL during the afternoon and exited off the SE GA coast into the Atlantic waters by the late afternoon and offshore of the NE FL coast by the evening. Strong dynamics with this system included a very strong low-level jet of 45-55 knots and 0-6 km shear of 50-70 knots, which along with good lapse rates aloft around 6.5 C/km and high dewpoints into the upper 60s created 500-800 J/KG of CAPE. These ingredients promoted threat of damaging wind gusts of 50-70 mph or greater, hail, and isolated tornadoes within more intense storms embedded within the Squall line.

A brief EF0 tornado with maximum winds near 80 mph produced widespread tree damage just east of Interstate 95 in the Bartram Park area of the Jacksonville Southside. The tornado touched down just west of Bartram Park around |4:08 pm, north of Arching Branch Circle, and tracked quickly |to the ENE across Woody Vine Drive and Roundleaf Drive before|dissipating across a wooded area just west of I-95 around |4:10 pm. There was some minor structure damage to gutters |and window screens, but the majority of damage included |snapped trees and large limbs blown down. There were |some trees were blown down and uprooted, indicative of a |descending rear flank downdraft.

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 19:58 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.
