EF0 tornado, (Fll)Ft Laudrdl Intl to Pembroke Pines, Florida, April 12, 2023

From (Fll)Ft Laudrdl Intl to Pembroke Pines, this EF0 tornado ran 1.7 miles across Broward County on April 12, 2023, touching down at 9:40 PM EDT and reaching 50 yards wide. It killed nobody, and did $50,000 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

17 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 85 mph.

  • Limited damage indicators. May have been at tree level.
  • Carport lifted. Small part of roof peeled back
  • Siding torn off on west side of home. Greater than 50% roof loss
  • Significant uplift of roof.

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 nearly stationary front began to move slowly northward across South Florida on April 12th, focusing deep moisture over the region. An mid to upper level low pressure over the NW Gulf of Mexico and an upper level jet stream over the eastern Gulf of Mexico contributed to providing the necessary atmospheric forcing for areas of persistent heavy rain and strong thunderstorms across most of SE Florida.

A small tornado began in Dania Beach on NE 6th Court just south of Ft. Lauderdale/Hollywood International Airport, causing mainly fence and tree damage to the surrounding neighborhood. The tornado skipped as the parent storm moved WNW across Federal Highway, with the next area of tornado damage noted at a church on NW 5th Avenue and 3rd Terrace where the west edge of the roof peeled and blew off to the east, and the front door facing north was blown in. Extensive tree damage was noted westward along Old Griffin Road next to the Dania Cut-Off Canal, then damaged at least half a dozen mobile homes in the Ocean Waterway community west of Bryan Road and east of I-95. The mobile home damage was in the form of peeled roofs, metal siding torn off, and damaged power poles. ||The tornado was rated on the high end of the EF-0 scale based primarily on damage in the mobile home park. A tornadic debris signature (TDS) was also noted on radar with this tornado. Damage totals are estimates.

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 General Thunderstorms Risk. The outlook in force was issued at 00:52 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.
