EF0 tornado, Locust Grove, Georgia, February 12, 2019

This EF0 tornado ran 0.9 miles across Henry County on February 12, 2019, touching down at 2:12 PM EST and reaching 100 yards wide. It killed nobody, and did $15,000 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

20 damage points were recorded along this path by NWS FFC, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 75 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 sharp upper-level trough and associated strong cold front swept through the region resulting in numerous reports of damaging thunderstorm wind gusts and a few isolated tornadoes across parts of north and central Georgia.

A National Weather Service survey team found that an EF0 tornado with a maximum wind speed of 75 mph and a maximum path width of 100 yards touched down in the Locust Grove area of southern Henry County. The tornado snapped or uprooted trees as it moved southeast along the north side of Highway 42 between Barnes Drive and Davis Road. Just before the tornado lifted, the front and side porches of a house were lifted and then collapsed. No injuries were reported. [02/12/19: Tornado #3, County #1/1, EF-0, Henry, 2019:003].

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

Area Forecast Discussion
National Weather Service Peachtree City GA
200 PM EST Tue Feb 12 2019

.SHORT TERM /Tonight through Wednesday Night/...

A cold front is expected to exit the area tonight. A line of heavy
showers and some brief thunderstorms are associated and will move across
the rest of the forecast area this afternoon and possibly early evening
before ending. Some strong gusty winds have been associated with
the line.

A much drier airmass will move over the area during the overnight
and continue the rest of the short term.

Forecast low temperatures are running about 2-6 degrees above normal
tonight and within a few degrees of normal Wednesday night.
Forecast high temperatures are running near to about 2-4 degrees
below normal for Wednesday.

.LONG TERM /Thursday through Tuesday/...

No significant changes made in the Long-Term Forecast period at this
time. Still looks like a wet pattern setting up across the region as
the upper flow remains fairly flat but active. Please see the
previous Long-Term Forecast discussion below.

20

Previous LONG TERM Discussion /Wednesday Night through Monday/...

The long term portion begins in one of the few dry periods as
surface high resides right over the area through Thu morning. This
looks to be the coldest morning of the long term as good
radiational cooling setup allows for sub freezing conditions over
a good portion of the northern tier.

Zonal flow aloft means systems will move in quickly and often
beginning Fri. Already some differences creep into the models with
the GFS having a sharper trough and consequently more QPF. Have
used a blend for now which still yields likely pops for the
northern tier and chance for Central GA. More substantial system
in store for Sat as low pressure tracks across the Tennessee
Valley and drags a frontal boundary across the area and what looks
like a washout of a Sat for most areas.

With the zonal flow aloft not going away, we just never can really
get a clearing front through the area. Sunday looks like it could
be wet as well now, at least for Central GA with North GA possibly
clearing out early in the day. Enough instability present to
warrant inclusion of slight chance thunder for Sunday afternoon.
It should be noted that in the super long term, this pattern looks
to persist and has the chances of bringing copious amounts of
rainfall to portions of the area should models verify.

This Hazardous Weather Outlook is for portions of North and Central Georgia.

.DAY ONE...This Afternoon and Tonight...

Patchy dense fog will continue to impact portions of eastern
Georgia through the rest of the morning hours.

A line of showers with isolated embedded thunderstorms will move
through the area through this afternoon and evening. Although
widespread severe weather is not anticipated, a few of the storms
could be strong producing damaging winds and heavy rainfall. An
isolated tornado cannot be ruled out, especially across portions
of west and central Georgia later this afternoon.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday...

Isolated thunderstorms will be possible again on Sunday as a
series of storm systems move across the outlook area. In
addition, some localized flooding will be possible as the
potential for locally heavy rainfall will exist.

.SPOTTER INFORMATION STATEMENT...

Spotter activation is not requested but spotters are encouraged
to submit reports of severe weather through the web by going to
weather.gov/atlanta.

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.
