EF4 Hattiesburg tornado, Mississippi, February 10, 2013

From Oak Grove to Macedonia, this EF4 tornado ran 21.6 miles across Lamar, Forrest and Perry counties on February 10, 2013, touching down at 5:03 PM CST and reaching 1,320 yards wide. It killed nobody and injured 71, and did $39 million 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 mph

    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 mphthis tornado

    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

70 damage points were recorded along this path by NWS JAN and NWS MOB, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF3. The highest wind the damage implies is 162 mph.

  • Roof torn several brick buildings...many power poles snapped.
  • Several trees uprooted or snapped. Home on south side of circulation had roof damage.
  • trees snapped mid-trunk or topped out and with large branches broken in several trees.
  • 2 mobile homes with side panels blown off and loss of underskirting. Also adjavent wood frame home list section of siding.

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

An approaching cold front, an unusually high amount of wind shear, and sufficient instability resulted in an outbreak of severe thunderstorms across portions of the lower Deep South, including a violent tornado that moved through Hattiesburg. During the morning hours of February 10th, a line of severe thunderstorms moved into the ArkLaMiss, downing trees and powerlines over portions of southeast Arkansas, northeast Louisiana, and central Mississippi. There was also a barn destroyed near Silver City in Humphreys County. The storms continued to push eastward through the early afternoon, then began to slow down as the cold front began to stall. To the south and east of this line of storms, several supercell thunderstorms developed in the more unstable air mass over south Mississippi, with many of the storms exhibiting strong rotation on radar. Shortly after 4 pm, a tornado developed over southwest Marion County near the Pickwick community and tracked across the county into far western Lamar County before lifting. The same storm which produced this tornado continued eastward across northern Lamar County, producing a large tornado which touched down west of Oak Grove and tracked through the very populated West Hattiesburg area. The tornado continued into Forrest County, tracking through the cities of Hattiesburg and Petal before ending in northwestern Perry County. Considerable damage occurred along the path of this storm, and several people were injured. Scattered severe storms continued to affect the Pine Belt area through the remainder of the evening and into the early morning hours of the 11th, before finally moving out of the area.||In addition to severe weather, flash flooding was a major issue in several areas. From the 10th through the early morning hours of the 11th, the heaviest rainfall occurred over parts of southeast Mississippi, where 5 to 7 inches of rain fell and flash flooding was reported in the area. Rainfall amounts of up to 3 1/2 inches occurred in the Jackson metro area, leading to considerable flash flooding. Quick rises occurred on several streams in the city of Jackson.

The tornado started along Highway 589, where some limbs and small trees were blown down. It became intense rather quickly, producing significant damage as it moved through the West Lake Serene area. The tornado reached its maximum intensity in the area around and just southwest of Oak Grove High School where maximum winds were estimated at 170 mph, which is EF-4 strength. There was a brick home in a subdivision southwest of the high school, just west of old Highway 11, that was completely leveled with all interior and exterior walls down, and a fair amount of large debris was blown downstream. Additionally, very high end timber damage occurred in this location with a number of trees showing debarking and denuding. Several other homes in this subdivision also sustained EF-2 to EF-3 damage. As the tornado crossed old Highway 11, it produced extensive damage on the campus of Oak Grove High School. The field house adjoining the football stadium was destroyed, the baseball stadium and a large metal building adjoining the stadium were essentially destroyed, and several large steel/concrete light standards were snapped at both the baseball and football stadiums. A vehicle was thrown from the parking lot adjoining the baseball stadium, up a small hill and was deposited near the pitching mound in the middle of the baseball field. The main building of the high school also suffered roof damage.||The tornado then moved northeast into the heavily populated areas of Oak Grove and West Hattiesburg, including areas along Lincoln Road Extension, Weathersby Road, Oak Grove Road, and the area just south of Highway 98 along Clark, Lamar and Foxgate Avenues. Numerous homes were destroyed or suffered major damage, and a few homes showed evidence of high end EF-3 damage. Dozens of power poles were snapped and extensive tree damage occurred. Video evidence and ground survey damage appeared to indicate that the tornado was multi-vortex in nature during its Lamar County portion. Just before crossing Interstate 59, it caused significant roof damage to a number of apartment buildings just west of the interstate. In total in Lamar County, emergency management indicated that 51 homes were destroyed and 170 suffered major damage.||The tornado then moved into Forrest County just to the south of Hardy Street damaging numerous homes with the damage in the EF-2 and EF-3 category. It then crossed Hardy Street impacting the southeast corner of the University of Southern Mississippi campus. Numerous buildings were damaged in this area including several campus buildings and a large church. Numerous power poles were blown down in this area and several metal traffic lights were bent or torn off their bases. Damage in this area was also EF-2 and EF-3.||The tornado continued across Highway 49 impacting multiple neighborhoods. Numerous roofs were blown off houses and many trees fell on houses and vehicles. The tornado crossed North Main Street causing significant damage to the Red Cross building, the Girl Scouts building, and bending large metal poles at the Hattiesburg High School athletic fields. The tornado then moved across east 7th Street causing significant damage to several large brick buildings. Damage in the area between north Main Street and east 7th Avenue was in the high end EF-3 range with maximum winds around 160 mph.||The tornado continued into Petal with the most significant damage occurring to an Ace Hardware store on South Main Street. Numerous homes in the vicinity of the hardware store also had roofs torn off and exterior walls collapsed. This damage was also rated high end EF-3 with maximum winds around 160 mph.||The tornado began to weaken as it crossed the Evelyn Gandy Parkway to the northeast of Petal. Damage in this area was mainly EF-1 and EF-2 and consisted of roof damage and snapped trees. The tornado strengthened one last time as it moved through a neighborhood just off Twin Lakes Road. Numerous well built homes experienced EF-2 damage to the roofs in this neighborhood. The tornado weakened as it approached the Perry County line and dissipated a couple of miles into Perry County. Damage at the end of the track was in the EF-0 to EF-1 range.||In Forrest County, emergency management indicated that 133 homes were destroyed and 207 suffered major damage. There were 63 reported injuries.||This is the second violent tornado to impact Lamar and Forrest Counties in recorded history. The other violent tornado was the infamous Purvis tornado on April 24, 1908 that was on the ground for 155 miles and impacted many counties across Mississippi. In total, 143 people were killed by this tornado, including 60 in Lamar County and 4 in Forrest County.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON MS
422 PM CST SUN FEB 10 2013

.DISCUSSION...TONIGHT THROUGH SATURDAY...ACTIVE DAY ONGOING WITH A
FEW SEVERE THUNDERSTORM WARNINGS AND AN UPTICK IN TORNADO WARNINGS.
THE MOST SEVERE ACTIVITY IS MOSTLY SOUTH OF I-20 WHERE THE BETTER
MOISTURE...INSTABILITY AND HELICITY IS LOCATED. THIS IS ALSO SOUTH
OF THE WARM FRONT WHICH IS ROUGHLY CUTTING ACROSS THE I-59 CORRIDOR
UP THROUGH CENTRAL MISSISSIPPI. STORMS ACROSS THE PINE BELT HAVE
DEVELOPED AND CONTINUE TO MOVE INTO AIR CHARACTERIZED BY 600-800
M2/S2 HELICITY VALUES. MODERATE RAIN WITH EMBEDDED THUNDERSTORMS IS
MOSTLY FOUND NORTH OF I-20. CONDITIONS ARE IMPROVING WEST OF THE MS
RIVER AS THE BULK OF THE RAIN HAS MOVED EAST OF THERE. THE COLD
FRONT IS STILL FURTHER WEST AND JUST TO THE EAST OF SHREVEPORT. THIS
ACTIVITY IS EXPECTED TO CONTINUE TO TRACK TO THE EAST THROUGH THIS
AFTERNOON AND EVENING. MODELS REMAIN CONSISTENT IN SHOWING THAT THE
FRONT WILL STALL AROUND SOUTHERN MISSISSIPPI LATER TONIGHT. THIS
WILL HELP TO KEEP SOME CHANCE FOR SHOWERS THROUGH THE NIGHT ACROSS
THE FAR SOUTHERN PORTIONS OF THE PINE BELT REGION. CURRENT FLASH
FLOOD WATCH EXPIRES AT 00Z FOR SOME LOCATIONS. HAVE GONE AHEAD AND
LOCATED WHERE THE HEAVIEST RAIN IS FALLING NOW AND WILL CONTINUE TO
FALL THROUGH THE EVENING AND POTENTIALLY OVERNIGHT. SOME LOCATIONS
MAY GET TRIMMED THIS EVENING AS HEAVIEST RAIN SHIFTS SOUTH.
LOCATIONS SOUTH OF I-20 FROM ABOUT NATCHEZ TO PORTIONS OF THE I-59
CORRIDOR WILL REMAIN UNDER THE WATCH THROUGH 12Z WITH POTENTIAL FOR
1-2 INCHES ADDITIONAL WITH LOCALLY HIGHER.

THINKING REMAINS SIMILAR AS PREVIOUS FORECASTS IN THAT THE FRONT
WILL REMAIN STALLED ACROSS THE SOUTH THROUGH TUESDAY. A FEW
DISTURBANCES WILL MOVE ALONG THE FRONT BOTH MONDAY AND ESPECIALLY
TUESDAY. THE FIRST DISTURBANCE IS A RATHER SUBTLE SHORTWAVE BUT THIS
SHOULD BRING THE FIRST ROUND OF RAINFALL ESPECIALLY MONDAY AFTERNOON
FOR THE SOUTHERN TWO-THIRDS OF THE REGION. THE FAR NORTHERN DELTA
MAY BE THE DRIEST OF THE ENTIRE CWA FOR THE NEXT FEW DAYS. AN EVEN
STRONGER DISTURBANCE AND ASSOCIATED SFC LOW WILL TRACK ACROSS THE
REGION TUESDAY INTO TUESDAY EVENING...BRINGING THE LAST BOUT OF
RAIN(AND EVEN POTENTIAL FOR SOME THUNDERSTORMS) TO THE REGION. WITH
1.2-1.5 INCH PW VALUES STILL PRESENT ACROSS THE MAINLY I-20 AND
SOUTH...THIS SHOULD EFFICIENTLY DELIVER AN ADDITIONAL 2-4 INCHES OF
RAIN THROUGH TUESDAY NIGHT. THE BEST LOCATION TO SEE MOST OF THIS
HEAVIER RAIN WILL BE ALONG AND SOUTH OF I-20 AND AN EXTENSION TO THE
CURRENT FLASH FLOOD WATCH WILL LIKELY BE NEEDED IN THESE LOCATIONS.
THE SFC LOW WILL MOVE ALONG SOUTH MS AND TRACK UP THROUGH ALABAMA
EARLY WEDNESDAY AS THE UPPER TROUGH MOVES ACROSS WESTERN TN AND
NORTHERN MS. SOME ADDITIONAL SHOWER ACTIVITY WILL BE ASSOCIATED WITH
THIS UPPER TROUGH PASSAGE  BUT AMOUNTS SHOULD BE LIGHT ON WEDNESDAY
MORNING. THIS WILL BE FOLLOWED BY MUCH DRIER AND SLIGHTLY COOLER AIR
WED-THU. A STRONG SHORTWAVE TROUGH IN THE NORTHERN STREAM WILL DIG
SOUTHWARD THU-FRI AND SEND VERY CHILLY AIR INTO THE ARKLAMISS FOR
THE WEEKEND. SOME OF THE COLDEST TEMPERATURES OF THIS WINTER SEASON
ARE EXPECTED. /28/EC/

&&

.AVIATION...MVFR AND IFR CONDITIONS ONGOING TO THIS AFTERNOON AS
LARGE SWATCH OF SHOWERS AND THUNDERSTORMS CONTINUE TO MOVE THROUGH
THE REGION. THE MAIN AXIS OF RAIN IS NOW ALONG AND SOUTHEAST OF THE
NATCHEZ TRACE AND WILL CONTINUE TO BE IN THIS REGION THROUGH THE
EVENING AND SLOW SHIFT SOUTH. MAIN TAF SITES AFFECTED THROUGH 12Z
FROM SHRA/TSRA WILL BE KMEI/KHBG/KPIB. KJAN AND KGTR WILL BE AFFECTED
THROUGH 02Z. VIS COULD BE REDUCED TO 1/4SM IN +TSRA AND CEILINGS WILL
GO BELOW 1KFT. CLEARING OF RAIN AT KGLH/KGWO BUT CLOUDS CONTINUE TO PLAGUE THE
REGION THROUGH THE NIGHT. /28/

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.
