EF0 tornado, Lake Monroe Lake to Enterprise, Florida, June 6, 2020

From Lake Monroe Lake to Enterprise, this EF0 tornado ran 2.0 miles across Volusia County on June 6, 2020, touching down at 8:27 PM EDT and reaching 200 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

2 damage points were recorded along this path by NWS MLB, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 50 mph.

What the Weather Service recorded

Conditions became favorable for severe weather in central Florida due to enhanced winds aloft on the far eastern periphery of Tropical Storm Cristobal which was moving north over the central Gulf of Mexico. Scattered to numerous severe thunderstorms developed across Lake, Orange and Volusia counties producing areas of damaging winds and several tornadoes and waterspouts over inland lakes.

Numerous eyewitness reports, photographs and video were received from trained spotters and the public of a large waterspout that developed on Lake Monroe, which then came onshore briefly along the north shore of the lake as a rapidly weakening tornado. The waterspout developed on Lake Monroe at approximately 1927 LST and quickly became large, reaching an estimated maximum width of approximately 200 yards. The slow-moving waterspout then reached the north side of the lake near the 860th block of Lakeshore Drive in Enterprise at approximately 1934 LST as a rapidly weakening EF-0 tornado. The tornado dissipated between Lakeshore Drive and Jacob Brock Avenue, just east of the Florida United Methodist Children's Home and west of Broadway Street. An eyewitness near the point of dissipation, initially observed the waterspout over the lake, then described a complete lull of wind, followed by a increase of winds from the opposite direction, suddenly becoming very strong. Based on this report, along with only minor damage to trees near the lakefront, peak winds were estimated between 45 and 55 mph.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

The warnings

26 minutes of warning. NWS MLB issued a tornado warning for this county at 00:01 UTC, 26 minutes before the tornado touched down, in force until 00:30 UTC.

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.
