EF1 tornado, Jax Herlong Arpt to Cambon, Florida, June 6, 2016

From Jax Herlong Arpt to Cambon, this EF1 tornado ran 3.9 miles across Duval County on June 6, 2016, touching down at 3:25 PM EDT and reaching 180 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 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. EF186 to 110 mphthis tornado

    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

65 damage points were recorded along this path by NWS JAX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 100 mph.

  • Fence blown down, possible early stages of mesocyclone

What the Weather Service recorded

Tropical Storm Colin moved onshore the Florida Big Bend area late Monday June 6th and then tracked quickly over the local area that night. A band of heavy rainfall and strong thunderstorms moved across NE Florida on the east side of Colin during the afternoon of June 6th which produced strong tropical storm force wind gusts and subsequent wind damage including downed trees, power lines and some structural damage mainly along and east of the Highway 301 corridor in NE Florida. There was also one confirmed EF1 tornado touchdown within this squall that impacted the Westside of Jacksonville near Normandy and the Crystal Springs area. Tropical storm force wind gusts outside of thunderstorm activity started after midnight Tue morning (June 7th) across coastal locations with gusts generally between 40 and 50 mph. The heaviest rainfall amounts were observed Monday afternoon June 6th and range from 4 to 8 inches across much of NE Florida. SE Ga experienced less impacts.

The tornado touched down near Normandy Blvd and Blair Road around 3:25 pm local time. Damage in this area was minor EF0 damage with some fencing blown down and trees damaged. The vortex continued along Blair Road maintaining the same intensity until it reached Wood Dove Way. From there to Interstate 10, EF1 damage was observed. The funnel then moved across the Publix Distribution Center flipping empty trucks and then NNE to Arbee Road. As the Westside-Crystal Springs tornado dissipated, the thunderstorm rear flank downdraft moved through a neighborhood northeast of the dissipating funnel. The tornado dissipated around 3:35 pm. The rear flank downdraft contacted the ground near West Beaver Street and moved northeast through the Watershed Drive, Maple Ave, and Orme Road areas. The predominant damage was to trees with some roof damage on Maple Street. There were reports of damage to residences, businesses, and trees along the tornado path. Some homes had parts of roofs partially torn off or damaged. Maximum wind speed 100 mph.

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 Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 16:28 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.
