EF0 tornado, (Fll)Ft Laudrdl Intl, Florida, April 10, 2018

This EF0 tornado ran 3.2 miles across Broward County on April 10, 2018, touching down at 4:25 PM EDT and reaching 40 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 MFL, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 70 mph.

What the Weather Service recorded

Increasing moist south-southwesterly flow ahead of an approaching cold front lead to scattered shower and storm development along the east coast of South Florida during the afternoon hours. Interaction with the east coast seabreeze brought several strong to severe storms across Palm Beach and Broward Counties during the early to mid afternoon hours. Strong winds, two brief tornadoes, and small hail were reported with this activity.

Survey summary: Multiple eyewitness videos show a tornado touched down along the northwestern side of Fort Lauderdale-Hollywood International Airport near I-595, leading to damage to cargo and storage containers in the FedEx facility on the north side of the airfield. The tornado then moved east-southeast along the airport's northern taxiway, causing damage to a jet bridge on the north side of the terminal. The damage path becomes diffuse as it likely crossed Perimeter Road and US 1 along the immediate east side of the airport. The tornado then moved into the extreme |southern end of Port Everglades, where multiple cargo containers were flipped and damaged, along with eyewitness reports of port-a-johns being tossed about. The tornado then likely crossed the intracoastal waterway, and moved across the barrier island within Dr. Von D. Mizell-Eula Johnson State Port before moving offshore into the Atlantic Ocean.

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.

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. The outlook in force was issued at 19:57 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.
